Is Apache OpenOffice Safe for my MacBook Pro I am a first time Apple User.

I am coming from a PC with over 27 years experience and most recently windows 8 I had to return 2 new notebooks with windows 8 with nothing but problems so I really had it with microsoft and I am a brand new apple user of only 2 weeks so I went out and purchased a MacBook pro and what a difference. I worry way to much and was concerned about downloading Apache OpenOffice for my new MacBook Pro. Is it a safe program to put on my Macbook and is it stable or can I expect problems. I would greatly appreciate any help the community can offer me. Thank you very much for your help...Would I be better off downloading Apple's version of a spreadsheet & word processor I believe they are around $20.00 each Thanks again. 

Open Office is a suite of applications similar to Office 2007 for Windows. It is not 100% compatible with Office, but it is close. However, I would suggest using Libre Office. It is much like Open Office because they both come from the same original source code. But Libre Office seems to be better supported.

    Yes, just be sure you download it directly from the developer website: http://unity3d.com/webplayer. A fair number of file download sites bundle adware or other unwanted content with legitimate applications/plugins.

  • Is Fan Control Safe for your MacBook Pro?

    does anyone here have an experience using it?

    smcFanControl works fine. It won't hurt anything. You can't slow the fans down below the factory default setting.

  • Is it normal and safe for my macbook pro to be at this temp

    So I installed Starcraft 2 onto my 2010 Macbook Pro 15" i7 and I also installed Fan Control. When I play starcraft 2 i noticed that the fans get louder and some parts of the computer are hot. I checked the fan control to see the temps and they reach 60-65 degrees. Is this ok? What would be the threshold of the computer?

    If the CPU temperature of your machine rises into the high 90s (C.) and stays there even with the fans running at or near 6000RPM, then you may have a problem of some kind that requires attention. If the CPU temperature ever reaches 105°C, the MBP will shut down for its own protection. That is the upper limit of the CPU's safe operating range, according to Intel's specifications.

  • Is it safe for my MacBook pro retina plugged in while it's off?

    Hello Everyone, so I have read that putting your MacBook pro in sleep while plugged in all the time is safe as long as you run the battery once in awhile, but what about if I want to shut down my MacBook pro Retina off without unplugging the charger and just leave it on for the rest of the night and then just turn my macbook pro back on still without unplugging the charger? Is it safe, no KABOOM!!? Lol ok I'm going to sleep now and I will turn off my Mac and unplug it for now until further instruction. Thanks in advance and good night!

    you can leave it plugged in - when fully charged - charging stops to avoid overcharing your battery.
    do not fully discharge your battery to 0% constantly, doing so will shorten your battery life.
    good luck

  • Is time capsule the only wireless backup for a macbook pro that will work with Time Machine?

    I just got a macbook pro (mid 2012) and I was going to back it up, but the time capsule is very expensive so I was wondering if any other backups worked wirelessly with time me

    Any external hard drive can be used for a Time Machine backup, but for network backup I doubt you will find much if anything at a lesser price than a Time Capsule. Plus, the Time Capsule is also a network router.

  • IMac or wait for new MacBook Pro 2013 or 2014?

    I have a mid 2007 iMac model, and my PC laptop recently died- I am debating right now as to whether I should buy the iMac 2013 since it was recently updated or just wait for the MacBook Pro update said to be released sometime this month. I'm in need of a new computer for sure and can last for a bit on my iMac (it's staring to get really slow). I personally would want a MacBook Pro so I could bring it to school/classes but also going to partition it play some PC Games (they're not that graphic hungry, just TERA, MMO's).
    I was considering to get the 2013 iMac now and wait until next year for the rumored Sharp IGZO MacBook Pro coming out early 2014 sometime during the summer before next school semester starts. That being said, I don't want to risk the 2014 pro not releasing until AFTER the school semester.
    My second option (the safer route) is to wait for the new 2013 MacBook Pro to release this month (hopefully) and that would be the end of it.
    I just want to get the most out of my money as well as the reassurance that it would be energy efficient, durable to last for the rest of my college years. Thanks!

  • I've been using firefox for my macbook pro for the last three years but lately when it starts up, I hear a strange piano chord play. Have others experienced it?

    Only recently has Firefox for my macbook pro been acting strange when starting up. I will hear a piano chord play only once when the tabs are loading. Over the past two-three weeks on daily usage, this has happened three times. I'm just concerned my macbook has a virus/bug or if this can be resolved with changing a preference/setting in Firefox. I don't believe this is a problem with my computer itself and I have checked the notification alert sounds and none are the piano chords I'm hearing. I am currently using two add-ons: Tabs-mix plus and FVD Speed Dial if that helps.

    Does it happen when you start up in Safe Mode?
    '''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).

  • Virus protection for my macbook pro

    Does anybody know of a good Virus protection for my macbook pro? Some people say i dont need one is that true? I was hoping to get a cheap/reasonable priced protection for a lil extra help. Im worried about my laptop getting a virus.

    Thomas A Reed wrote:
    sigh. Discussions about anti-virus software here are a hot-button topic, and often cause virtual fistfights. Not your fault, of course, but now there's a lot of confusing information being thrown back and forth here. Let me try to clear the air a bit.
    First, regarding ClamXav, Kappy's link is fine, but I would refer you straight to the official ClamXav site rather than the MacUpdate page:
    http://www.clamxav.com
    There is another ClamXav site, ending in .org, that is fake. It's not related to the actual ClamXav. Don't go there. I'd love nothing better than to get that site taken down, but alas, that is not within my power.
    I have mixed feelings about ClamXav. I like the guy who develops it, and I like the way it works... but it's not always on top of things with regard to malware definitions.
    Regarding Avast, it is certainly not "the worst of the whole wretched lot" of anti-virus software. Neither is it something I would recommend highly. It has a tendency towards false positives, in my experience. Beyond that, I have not used it for a lengthy period of time, and cannot say more.
    Go to my Mac Malware Guide and get the information you need to learn how to protect yourself, and then make your own educated decision about anti-virus software, based on your needs and behaviors. I have some recommendations there, and you can also take a look at the results of my testing of Mac anti-virus software. (Be sure to read the whole thing, and don't just skip straight to the results, as the results are meaningless without understanding what they mean and what they don't mean.)
    With respect to your site and your basic research on the matter and limited time spent with these engines running, you have to see this from my side as well.  I have over 20+ client networks that run nothing but the full licensed version of Avast with just the AV filters turned on (none of the Firewalling built into it of any kind).  2 of those clients are full Mac networks with 15+ Macs on them and they run the Mac version without issue.  Their systems run at the same speed as they did without anything else on them.  I also run the software myself daily an my system has no issues with slowness or anything.  I have run Avast for the past 6+ years without problems with false positives or system corruptions of any kind, the same cannot be said for other platforms like McAfee and Norton who's bad signature updates have crippled entire networks.  I have looked at numerous options from ESET to AVG Free and none of them have as small a footprint on the system as Avast in my professional opinion (one backed by over 15 years in the IT industry).  While as of late I'll agree that the PC version of the software has had some additions to it that I don't agree with (like the newly added features of 8.0), the Mac version is still pretty basic in contrast.  As such, even the PC side isn't bad, you just have to do a custom install and just exclude the additional options you don't want.  Ultimately, they're adding it in there to try and protect idiot users more, but there's only so much you can do to keep people safe without piling on the security layers.
    Anyway, as Thomas said... discussions about AV on Mac forums can go on for hours, but the fact remains that you run a risk with and without something on your system.  Utimately it's your call to make, just be open minded and do your research instead of just taking the word of some home user of Macs with lot of points who've used these systems for over 10 years and are more proficient at protecting themselves than you are as a novice user.  That is the best suggestion I can give you.

  • Looking for a Hard Drive RAID System for 17" MacBook Pro, any Suggestions?

    I purchased my 17" MacBook Pro in Nov. 09 and it does have an ExpressCard/34 slot. What I am looking to do, is purchase a 4TB Caldigit VR External Hard Drive and put it on RAID 0. I Love the performance fact, but I don't feel too safe, because if that drives go down, there goes my data. So what I want to do is use Carbon Copy Cloner and find another External Hard Drive that will backup my Caldigit VR, since it will be RAID 0. Any Suggestions would help out very much! I am using this RAID System to store my HD Video using Final Cut Pro Studio. I know I can set up the Caldigit VR as a RAID 1, but I would rather set it up as a RAID 0 and have another hard drive back the data up. Let me know if you have set up a RAID System for your MacBook Pro and what you did. Also what express cards do you recommend?
    Thank you,
    Chad

    There is a difference technically between this iStorage unit and the Cal Digit stuff. Cal Digit includes a hardware raid controller, and removable drives. The iStorage Pro unit relies on your computer's CPU to control the raid... so will tax things like render times... plus just to play a software raid can take as much as 30% of your CPU's cycles to do it...
    That said, it may not matter if you're working in lower resolution files, or lower data rate stuff, either company makes great gear though. Both are intended for use with video systems. But ya do get something for the extra money on the CalDigit gear.
    But if all you want to use it for is backup of data... anybody's drives would do this... doesn't have to be a raid either. Single FW drives will certainly hold the data as backup even if they won't play it without dropping frames.

  • HT4110 What is the best battery setting for the MacBook Pro 13 Retina display?

    I want to know the best setting for the battery for the MacBook Pro 13 Retina display.

    To add just a little
    Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
    And best "tip" is if its near a socket,...plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)", however again, not plugged in all or most of the time.
    http://www.apple.com/batteries/notebooks.html
    "Apple does not recommend leaving your portable plugged in all the time."
    General rule to remember of Lithium batteries is:
    Never drain them LOW  & dont always/often store them HIGH
    While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
    *A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge. 
    DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count.  *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                              (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
    *Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
    *However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
    Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                        This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
    LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
    A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
    Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
    The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
    Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
    Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
    From Apple on batteries:
    http://support.apple.com/kb/HT1446
    http://www.apple.com/batteries/
    Storing your MacBook
    If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
    Considerations:
    Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
    In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
    Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
    Ultimately counting charge cycles is of little importance.  Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery. 
    Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
    Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
    Peace

  • I am looking for a (free, ideally) virus scan/check for my MacBook Pro -- any suggestions?

    I am looking for a (free, ideally) virus scan/check for my MacBook Pro -- any suggestions?

    Mac users often ask whether they should install "anti-virus" software. The answer usually given on ASC is "no." The answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There  is a threat, and you need to educate yourself about it.
    1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to log in to it remotely. That threat is in a different category, and there's no easy way to defend against it.
    The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
    OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
    2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
    The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
    The following caveats apply to XProtect:
    ☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
    ☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
    As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
    3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
    Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
    ☞ It can easily be disabled or overridden by the user.
    ☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
    ☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
    Apple has so far failed to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. These failures don't involve App Store products, however.
    For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
    4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
    5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, and a technological fix is not going to solve it. Trusting software to protect you will only make you more vulnerable.
    The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the scam artists. If you're smarter than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
    Software from an untrustworthy source
    ☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
    ☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software.
    ☞ Rogue websites such as Softonic and CNET Download distribute free applications that have been packaged in a superfluous "installer."
    ☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
    Software that is plainly illegal or does something illegal
    ☞ High-priced commercial software such as Photoshop is "cracked" or "free."
    ☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission.
    Conditional or unsolicited offers from strangers
    ☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
    ☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
    ☞ You win a prize in a contest you never entered.
    ☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
    ☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
    ☞ Anything online that you would expect to pay for is "free."
    Unexpected events
    ☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
    ☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
    ☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
    ☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
    I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
    6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
    Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
    Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
    Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
    Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
    7. Never install any commercial "anti-virus" (AV) or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
    Why shouldn't you use commercial AV products?
    ☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
    ☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
    ☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
    ☞ Most importantly, a false sense of security is dangerous.
    8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
    An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
    Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
    London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
    You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in everyemail attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
    The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
    9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
    10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It's as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.
