Does this program include virus and web protection?
I was about to install McAfee to my desktop and forgot I had put Firfox Home on my computer. Will these conflict? Am I already secure? I have Pop up blocker with Verizon Yahoo on the desktop. Please advise how to proceed with McAfee download or not. Thanks
Firefox is not an anti-virus program, you will still need to install an anti-virus program.
There is no need to pay for one, there are free alternatives available such as [http://www.avira.com/en/avira-free-antivirus Avira AntiVir Personal] and [http://www.microsoft.com/security_essentials/default.aspx Microsoft Security Essentials].

When I try to open up this program, Pacifist, I receive this error message. Here's a screenshot. http://i.imgur.com/v717w.jpg What does this error message mean and how do I solve it?
It sounds like some of the Unix Executable commands were removed (or the permissions to those were modified) out of the /usr/bin/ folder. You can try opening disk utility and repairing permissions on Macintosh HD or you can reboot your computer and holding down option-r when it comes back up to reinstall Lion again. This will not delete your personal information or applications you have installed but it would be best to back it up to Time Machine before you do. The article on how to do this is here. (http://www.apple.com/macosx/recovery/) I have had to do this before and it works like a charm. It should fix your issue but grab a cup of coffee because its going to take about 35 - 40 minutes depending on how fast your computer is.

I believe songs purchased in iTunes can be downloaded to a max of 5 devices. Does this count include the unregistered devices. ie. If I have already registered and downloaded music on 5 devices and now If I unregister one of the older device, can I go ahead and download songs in a new device ?
You can have a maximum of 5 computers authorized to play DRM-restricted content purchased from the iTunes Store. You can have a maximum of 10 devices (computers and iOS) associated to your Apple ID.
However, since all music sold on the iTunes Store has been DRM-free since late 2009 there is no longer a number of devices restriction for music. It is possible to sync, via USB or Wi Fi, an unlimited number of iOS devices. -
TS2570 Does this also include the scenario where the grey screen has a picture of 2 disk drives?
Does this also include the scenario where the grey screen has a picture of 2 disk drives?
One is labelled Macintosh HD and the other is Recovery HD.
The computer doesn't always start up like this but it has a few times now.This screen shows up if your holding the option/alt key down or perhaps if it's stuck or damaged.
It's called Startup Manager and shows your bootable options.
Another possible cause is your PRAM is not remmebering the System Preferences > Startup Disk selection.
Do a #2 Reset PRAM and head to System Preferences > Startup Disk and set it and hopefully that should resolve the issue.

It has been doing this for a week and the music is faint while the static is louder than it. I try plugging it in to my iTunes and when I un-plug it, it still makes the loud static noise. I have also tried tapping my knuckle on the back of my ipod nano. This has not damaged it at all nor caused this to my ipod. There is no water damage to the ipod. Only a few scratches from a couple drops. The drops have been on concrete but not at a very high distance. How to I stop this? Do I need to replace my ipod instead?
Have you tried a different pair of earbuds/headphones to rule out a pair of damaged/faulty ones? You might also want to make sure the headphones are securely and firmly seated in Nano's headphone jack. Lastly, check the headphone jack for any signs of debris or damage. You may need to have the headphone jack replaced either by Apple or a third party repair company.
I assume this static is present on any track you listen to versus only particular ones?

iPad--third generation shuts off antenna/hotspot after a few minutes of non-use.
Happens in 3G and LTE VZ environment.
Turning hotspot off and on getsw things working again.
Does Apple have antenna on a timer so it shuts off after a few minutes?
Does this happen on Mini and Retina as well?
FLAGSTAFFLARFixed!
Two things together have restored connectivity.
1. I changed the name under Settings > General > About > Name from My Name's iPad to iPad of My Name. I read somewhere that iOS 7.0.1 or 7.0.2 (I forget which) sometimes had issues with apostrophes here. Easy enough to test.
2. I then reset (again) the APN settings under Settings > Cellular Data > APN Settings > Personal Hotspot and reentered our provider's info (APN, Username, Password) there.
I don't know WHY it worked, but the personal hotspot is now happily sharing (again) internet connectivity with my MacBook Pro. -

Virus And Malware Protection for my iMac Yosemite 10.10.1
Hi,
My iMac starting opening random websites and I installed a free copy of Avast to take of it but I want to buy the best one. I'm looking for Virus and Malware protection for the lastest Yosemite.
Thanks!You installed adware along with something else you installed.
Download and run Adware Medic.
Avoid purchasing any type of AV software. All such software only slows down Macs (and PCs), and for the most part, are utterly useless. -
How does this program group and cluster these button values into an array?
In the attached program, there are 6 buttons in a cluster and 1 individual button. These buttons control a bunch of different relays to control power to different components of a single device. Right now the program works in that I can control the 6 buttons, the LED turns on in the board and the power is being transmitted. What I do not understand is how it is doing this. I ran the program with the highlight execution on and at the start of the read from array component, if say I pressed button 6 and hit ok, it reads #6, where did these get defined and labled? and if i wanted to add another button/relay how do i do this? If someone could explain step by step how this is grouping the relays on the board into an array and then controling them I would really appreciate it. Thanks.
Solved!
Go to Solution.
Attachments:
Cluster to Array.vi 85 KBThe #6 your seeing is the number of elements in the array not a value for the array.
Now for some deeper explainations. From the code it appears that exactly 1 of 6 valves may be used and an additional valve may be in one of two possible states.
When the program is run the cluster of buttons is initiallized to all False. and we enter the outer while loop where a sequence structure starts. In the first frame of the sequence we initiallize a shift register to hold the current value of "Buttons." and this loop runs unthrottled (Add a wait for next ms multiple to this loop to prevent using 100% of the CPU!)
For each iteration the buttons are read and if a change has occured to any value buttons that were previously True are reset to False to prevent opening more than one valve.
When the user presses OK or stop- the current "Buttons" value is passed to the next frame. This frame convertsthe 7 boolean values to a integer where each valve is controlled by a seperate bit of the integer (Isolation is bit 6 and bits 0-5 each control a mixing valve)
Now I'd strongly recommend reworking the DAQmx calls- it is pointless to initiallize the task each time you want to use it- Create the task in the initialzation case and wait until the user exits to destroy the task. And well a sequence structures are frowned on- (there are better ways to do this)
As far as adding a relay- right now the relays are associated to the hardware by their index position in the cluster (element 1 = bit 0 etc....) to add a new valve you would need to decide what bit you would use to drive it and code in that bits' value to write a 0 in that bit. (hint the 40 constant is realy 0x40 right-click>visable items>show radix )
Let me know if you need further elaboration

Best virus and hacker protection for mac book pro?
What is the best protection for my back book pro against hackers and virus?
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. -
I notice many of us seem to have the same problem, does anyone ever answer our questions online?
We paid to use this program, we would not have bought the program unless we had a use for it. I thought this would be much faster than OCR, but I am finding that it is worthless unless it works and so far that isn't happening.Hi itsjudyj,
Can you please tell me a bit more about the files that you're converting? How large are they (there's a 100MB file-size limit), and are they text, images, or both? File size or complexity can cause the ExportPDF service to time out before it can process the files.
Other things to check:
Clear the browser cache and try again.
Make sure that you're using a supported web browser (http://www.adobe.com/acom/systemreqs/)
Try a different browser
Please let us know how it goes.
Best,

I rather regret avoiding the OP's earlier post asking how to combine two classes. I looked at the two classes posted and realized the best thing to do was actually to break them into more classes. But I also realized it was going to be a big job explaining why and how, and I just don't have the patience for that sort of thing.
So now we have a Big Ball Of Tar™ and I feel partly responsible. -
Does this program actually print or export?
Man, I have been sitting here for ages trying to get Ap to export or print something. I've asked it to just do a little 5X7 and the epson didn't even light up.
I have a 350 mb film image. Just one. I want to know that this program will print 24" images before I buy it.
It's been exporting for 20 minutes.Very simply, I have done the edits upon the image that I'd like to save. Once I have finished them, I click on export so that it will save to my desktop. I just want to generate a version of an image that I can print and use.
Instead of a super-high resolution film shot, I have opted for a simple digital shot. These files are generally under 50 megs from photoshop.
I clicked "export" from file, then "version" from the drop-down menu.
I am going on 6 minutes now and still, no file on my desktop. The little spinning progress wheel is still doing its thing at the bottom of the screen. -
Why does this program not stop when not highlighted.
When I highlight the execution of this program it runs through and stops. However when I take off the highlight then the program does not quit running. I have encountered this problem on other programs as well. What causes it?

isotonic.vi 180 KBHello,
Thank you for contacting National Instruments.
I took a look at your VI. I think the problem may be that you are using a Continue if True loop condition in your first While Loop. If you press the stop button wired to this condition or if an error is generated in your VI, that first loop will continue to run indefinitely. Try right clicking the loop conditional and changing it to Stop if True. You may then need to change your Less? function to a Greater? function within that same loop to preserve the intended behavior of your program
I hope this solves your problem. If not, let me know.
