How I know if my computer have a virus?

My computer is slow and the itunes show up by his self? is a virus?

It's almost certainly not malware. See my Mac Malware Guide for more information on that topic. (Note that my pages contain links to other pages that promote my services, and this should not be taken as an endorsement of my services by Apple.)
For troubleshooting speed problems, see the Mac OS X Speed FAQ. As for iTunes starting by itself, there are a number of ways to trigger that, such as accidental button presses on an Apple Remote, pressing F7, F8 or F9, connecting an iOS devices, etc.

How to know if this computer can handle a certain monitor's resolution?

I am looking to buy a new monitor, but I am at a loss as to how to know whether my computer can handle the monitor's resolution, will be compatible with it. I used to run two NEC Multisync FE991SB (CRT) monitors side by side, and one of them died. Their native resolution seems to be 1280x1024 per monitor. I am considering buying a DoubleSight DS-263N (LCD) monitor, which has a native resolution of 1920 x 1200, and running it alongside the NEC Multisync FE991SB that has not died.

Any advice on how i can learn about compatibility? And on what card i need to buy, if i do need to buy one? Thanks.

Dear Discussion Folks,
Thank you all so much for your help. I think I understand now, as a result of your comments and this reply from NVIDIA customer support:
"I understand from your mail that you would like to know if GeForce FX 5200 Ultra supports your monitor that has a recommended digital resolution of 1920 x 1200.Please be informed that as per the NVIDIA records, the maximum digital resolution supported by this graphics card is 1600 x 1200 and the maximum analog resolution supported by this graphics card is 2048 x 1536. Since you have mentioned in your e-mail that the Apple's specs page says that the maximum digital resolution supported by this graphics card is 1920 x 1200, in this case, I request you to contact Apple Support over phone and get confirmed on this. The reason why I am requesting you to contact Apple is because, we at NVIDIA, manufacture only the basic chipsets for the graphics cards and sell them to Apple Computers. The Apple Computers produce the graphics cards using the NVIDIA chipsets."
This reassured me that there's no reason to worry about the appearance of a contradiction between the Apple tech sheet and the NVIDIA tech sheet. I went ahead and ordered this monitor today: the DoubleSIght DS- 265W.
(by the way, sorry about typing 1900x1200 when I meant 1920x1200).
After it arrives in a week or two, I'll update this thread to confirm that its resolution is supported by the GeForce FX 5200 Ultra card.
Thanks again,
Mark

# Question
My computer keeps freezing on me every 15 min do i have a virus I was told when you have mozilla firefox you don't need virus protection is that true and how can I scan if I have a virus and now do i get rid of it? edit

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
* [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
There are other things that need attention:
Your above posted system details show outdated plugin(s) with known security and stability risks that you should update.

How do I know if my computer has a virus?

Hello,
When I am on netflix and click on certain buttons more windows open on my computer. It didn't used to happen so I am worried that my computer has been attacked by a virus. How do I know if it is a real virus?
Thanks!

You may have installed one of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it.
Back up all data before making any changes.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates
if it's not already checked.

Your profile says you are using OS X Mountain Lion, so if that's true then you have all of Apple's anti-virus protection and if Software Update says you are fully up-to-date on all your Security, Java, etc. updates, then you are fully protected against all currently known malware that can impact OS X and Apple apps.
Keep Java (not JavaScript) disabled in all your browsers unless you must visit a site that requires it, and turn it back off as soon as you are finished to make certain you aren't one of the first to discover the next Java threat that will most certainly show up one day soon.

How to know when all callbacks have arrived

I use code like
for(a thousand times){
org.xbill.dns.SimpleResolver.sendAsync()//query my nameserver
public void receiveMessage(Object id,Message msg){
resolutionsvector.add(msg)
public void handleException(Object id,Exception e){
how do i detect when all callbacks are received?
i tried counting but sometimes the queries match the resolutions while there are still new queries to be created (do not know why thread creation/use is slow sometimes) and sometimes the program fails to detect it has finished.
thought of creating a resolution class for the resolutionsvector saving the state of all queries and using an additional thead to test if all are processed once every second.
is that a way to do it or is there a design pattern for 'joining' the threads without being able to do exactly that (the threads are controled by a resolver class i would like to use without changing it) i should apply (if applies: where do i find documentation?)
best regards

Two methods I can quickly think of that will help you,
I am sure that there is better ways of doing it just to lazy to check for and do them.
method 1): Interface
method 2): Runnable - run()--------------------
publc interface MyThreadListener{
public void threadGroupStarted();
public void threadGroupFinnished();
pubilc class GUI extends JFrame implements MyThreadListener{
private MyOtherThread mot = null;
public GUI(){
    init();
    mot = new MyOtherThread(this);
public void threadGroupStarted(){
    System.out.println("Threads Started");
public void threadGroupFinnished()
    System.out.println("Threads Finnished");
public static void main(String[] args){
    new GUI();
public class MyOtherThread{
private MyThreadListener mtl = null;
public MyOtherThread(MyThreadListener mtl){
    this.mtl = mtl;
public void startNewParallelThread(.....){
//Create a new thread in this class that will do the for(....) join().
//Add the following code:
mtl.threadStarted();
for (Thread t : collectionOfThreads){
    t.join();
mtl.threadFinnished();Creating a listener will enable you the have the second thread tell the first that it has finnished processing.
pubilc class GUI extends JFrame implements Runnable{//better to create a Runnable Object that implement

My macbook is slow how can I tell if I have a virus?

My MacBook is slow starting up and slow when I am on internet going to sites. I read somewhere that there is a adobe flash that is actually some sort of virus? I beleive I had the pop up and hit install. How do I fix if this is the problem?

Adobe Flash is not a virus but Flash content is very resource-hungry. Flash developers don't know or care about your hardware or bandwidth, both of which have limitations. Buying a new computer simply so that you can look at Flash-based advertisements makes little sense to me. Just avoid sites that use Flash.
There are no viruses for Mac OS X. Keep it updated with software from Apple using Software Update. Without a more specific description of your hardware, the amount of memory you have installed, what third party system modifications you may have made, and what version of Mac OS X you are using, it is difficult to provide more specific guidance than that.
Read the following to determine if something may apply to your concern:
Do not download or install any product claiming to magically "clean up" or "speed up" or "optimize" your Mac. Without exception, they will do the opposite. If you already did, you found the problem. Fix it.
If you're experiencing general slowdowns or "freezes" unrelated to Internet activity, the problem may be related to your computer or the software you installed and is something you may be able to fix, or at least improve. Aside from hardware failures and software that you install, including OS upgrades, there is no reason that your computer should not work precisely the same as it did when it was new.

How can you tell if you have a virus on your phone?

I was told there was a virus roaming around in Facebook. I got a junk message on my wall from a riend (who's account has been deactivated for months) about earning money online. She says she didn't send it. And for some reason suddenly I am unable to view my "status comment" notifications that I received in my message bin. I click on them and I get the option to open them but nothing happens. When the notifications come and I can see some wording of the message in the notification I can open them, but if it says "status comment" I cannot. I have removed and redownloaded FB hoping it will fix it but no luck. And suddenly it's messing with my ringers as well. I get strange notifications even though I have turned them off. My phone is less than 2 months old and FB is the one and only app that I have on my phone. Verizon doesn't seem to know anything about apps and hasn't been able to help me. What if I DID get a virus? I have insurance on my phone. Facebook isn't whats important to me, simply that I want to know who I can ask for help about a general question like a Virus on my brand new phone! Can anyone help?!!?!

There is some issue going on with multiple people related to the Facebook for BlackBerry notifications. You're not alone in that respect.
Not sure if the issue is with Facebook or the application, but I'm leaning towards Facebook since it's pretty much sucked on my PC the last several days, too.

How do you no if you have a virus or been hacked and how do you get rid of it

A couple of time now I have found my found on randon web pages or message is it possible i have been hacked or got a virus

Finding a strange site open in Safari isn't a conclusive sign that someone has hacked your iCloud account. You could simply be seeing redirects or "pop-ups" from some page you had loaded. This could easily cause tabs that you didn't realize were there to be noticed later.
Similarly, finding that you have received strange messages in the Messages app isn't suspicious. That just means someone is text-spamming you. You can block the individual doing this if you're running iOS 7.
However, if you are finding that your phone appears to be sending messages that you haven't sent, and has opened pages when all tabs in Safari were closed, then the iCloud account has been hacked.
If your iCloud account is also your Apple ID, and you think you have been hacked, you will need to immediately log in to appleid.apple.com and change your Apple ID password. While you are there, you should also enable two-factor authentication on your Apple ID, to prevent hackers from taking control of it, and potentially locking you out of your iOS devices permanently.

How can I determine if I have a virus. I think a may as my Yahoo account spammed my contacts Wednesday night.

If you're using Mac OS X, then you do NOT have a virus (I"ll even bet money on this).
There may be an exception here if you're running on Bootcamp or using a VM.
