What is the OS level strategy for ST03(work load analysis)

I mean Is there is any possibility to observe the things from OS level that we generally monitor from ST03

ST03(N) is a transactions that accumulates data from table MONI and various other tables. If you want to "look" at that data from OS level you need to either export the table MONI and write your own program to display that data or write a program, that does an RFC call into the system and gets that data for you (basically external monitoring tools such as Tivoli, HP Openview etc. do it like this).
If you would be precise, what you want to do, I could give a precise answer.
If your question is: Can I see the data from OS level that I see in ST03(N) the answer is no.

What is the best SLD strategy for CE?

We have some options like a single centralized SLD or a local SLD or something between them, e.g. an SLD for dev systems, etc.
Could you share your opinion -- what is a good SLD strategy for CE? Thanks!

Hi,
It wud depend on the landscape u have and requirement stategy.............
If you have a productive version...............obviously centralised SLD wud be preferred.....
Either case......juz to touch-base features of CE 7.1 i.e for exploration and R&D purpose..........lacal SLD and developer edition wud do.......

What is the Highest Level of MAC OS X level for iMAC G4?

What is the Highest Level of MAC OS X level for iMAC G4?
Right now, I'm running MAC OS X version 10.3.9.
Can I run Aperture iMAC G4?

OK,
I am now officially an certified idiot. I have 10.5.8 running, and was told that 10.4 makes a G4 run smoother. I did notice that, however I blamed it on firefox, safari and mail. Also I noticed that pages and word take quite some time to start up.
My apologies for all the confusion. But before I consider reinstalling 10.4, I thought I'd pop the question on this forum.
Do you think it will make a difference, and what are your thoughts on security risks if it is true that with 10.4 you can't run the latest versions of Safari and Firefox?
Thanks bluebird

1) What are the Master Data need to be check. They are Using the Strategy 20.
2) They have confirmed sales order for few customers. Forecast sales orders for few customers.How to map it in sap.
3) Where will i get Gross Requirement in SAP. Because MRP run will generates the net requirements.
4) Is there any report in SAP displays the Forecast values for the selected material.
Please help me on the above points.
Thanks

What is the new sap note for Ptax slabs of FY 2011-12.

Dear Experts,
we are currently using ECC 6.0, release 604, patch level 0035 and support package SAPKE60435. professional tax slabs not updated in table V_T7INP4.
what is the new sap note for Ptax slabs of FY 2011-12.

Hi,
The Profession Tax tables T7INP3 & T7INP4 are customizing tables in which the entries are to be modified. SAP provides the initial entries and, if there is any change in slab rates, then you would need to update these slabs manually.
Please delimit the slab code in table T7INP3 and then create a new slab code entry from the date of delimition for the new rates in table T7INP4.

HT4664 What is the best graphics card for FCPX?

In the nonstop anti-FCPX propaganda is an article of interest — posted 7/9/12 — comparing the benchmarks of FCPX and PP6.
http://www.streamingmedia.com/Producer/Articles/ReadArticle.aspx?ArticleID=83582 &PageNum=1
The system used was a 2 x 2.93 GHz Quad-Core Mac Pro from early 2009 running MacOS X version 10.7.4 with 12 GB of RAM and an NVIDIA Quadro FX 4800 graphics card with 1.5 GB of onboard RAM.
In most cases PP6 outperformed FCPX with this configuration. However, in the comments Ben Balser pointed out that FCP X's A/VFoundation engine wasn't ideal on the NVIDA card:
"Quadro is actually not the best card for FCP X's A/VFoundation engine, but great for CS6's Mercury engine, so the test is amazingly flawed right there. Try both on a 5780 card and watch things drastically change. I've done that test myself. Exporting to Compressor uses a MUCH more sophisticated encoding engine meant for higher level, professional transcoding, not simple outputs, which are faster using Export Media…"
Apple lists this card on its support page: http://support.apple.com/kb/HT4664
So,
What is the best graphics card for FCPX?

Ben,
Thanks for chiming in on that article. It would be good to have a benchmark comparison with the two systems each with a preferred card.
I'm hoping to see some other comparisons on this thread. Also, some links to other articles about best practices and configurations.

What is the maximum level that a role can be resolved to?

hi folks
can anyone tell me what is the maximum level at which expand role works. for example if i have a role which is then having 3 roles, each role has 2-3 users. will expand role work in this scenario?
Also plz tell me why expand role does not work properly with adhoc-roles i.e if 3-4 roles are bind to an adhoc role, then each user of the ROLE (roles bound to adhoc role) recieves the notification but if any one user of that ROLE closes the notification, the notification is closed for all the users of that particular ROLE;
This suggests that half of the job is done that is resolution to users, but the other half of this functionality is malfunctioning

What is the best virus protection for a Mac?

What is the best virus protection for a Mac?

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. 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 victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
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, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; 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.
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 actually been tested by Apple (unless it comes from the Mac App Store), 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. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
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 find some other way to evade Apple's controls.
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 presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. Beyond XProtect, Gatekeeper, and MRT, there’s no evidence of any benefit from other automated protection against malware. The first and best line of defense is always 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 malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source. How do you know whether a source is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
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, Java on the Web is 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. In Safari, this is done by unchecking the box marked Enable Java in the Security tab of the preferences dialog.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a specific task, enable Java only when needed for the task and disable it immediately when done. Close all other browser windows and tabs, and don't visit any other sites while Java is active. Never enable Java on a public web page that carries third-party advertising. Use it, when necessary, 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.
Follow the above guidelines, 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 from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their 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, the 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 itself may create weaknesses that could be exploited by malware attackers.
8. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. 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.
ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
9. The greatest harm done by security software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but they get a false sense of security from it, and then they may behave in ways that expose them to higher risk. Nothing can lessen the need for safe computing practices.
10. 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.

What is the cost and process for factory refurbish of a tx2-1375dx with a blown system board?cc=us

What is the cost and process for factory refurbish of a tx2-1375dx with a blown system board?
How would one go about arranging for such service?
Why is it impossible to contact a real human for support, either via online chat or phone?

Last I checked I am a real human, it is just that I do not work for HP and can't speak for them. HP would not be the place I would go for a "refurbish" job. They charge an arm and a leg for out of warranty service. You simply need to find someone to replace the system board (motherboard). It is also very likely on that model that you could have your system board repaired. There are many services on ebay that will repair the motherboard at the component level. The cost would be at or under $100 or so. I have more advice to give but many times I write a detailed response only to have the user never come back. I do check my posts so if you want more ideas just please respond. The tx2-1000 was one of the models affected by the nVidia issue that caused so many HP laptops made in the 2007-2009 era to fail prematurely.

What is the best external battery for iphone 4s

what is the best external battery for iphone 4s

I bought the Mophie juice pack™ powerstation from the Apple store for $80. It has more then enough power to quickly boost the charge on my iPhone4S to an acceptable level. It requires the standard 30pin/USB Apple cord to plug into it.
But unless you need to charge your phone from 5-100%, this battery is overkill. It's a real hassle having the Apple cord connected to your phone whilst there's a battery in your pocket and you end up looking quite strange with your "corded" smartphone.
I might recommend a battery case (Mophie has these), but they don't offer the protection that I need (I use a LifeProof case). Instead I would buy a smaller Mophie juice pack™ reserve (keychain, direct plug) to get out of a bind and then charge up your iPhone in the car, wall, airplane, etc.
My only concern with the above (direct plug batteries) is that the slightest bump and the battery becomes a lever that could break the 30 pin plug on your phone, just like that warily flimsy feeling when you put an iPhone in a dock.
Hope that helps, at least in the Mophie department!

What is the best security package for an imac using Yosimity

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 take control of 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 taken far too long to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. Those lapses 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, not machine behavior, and no technological fix alone is 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 Internet criminals. If you're better informed 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 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. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Rogue websites such as Softonic, Soft32, 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. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
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 padlock icon in the address bar 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 every email 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 can be 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.
