i think my macbook has a virus

[m00et01e]

hi i think my macbook has virus. every so often a bubble pops up at the front of the screen with the shut down/restart/sleep buttons. the shut down one is highlighted & if you do nothing or dont press cancel it automatically shuts down. it can pop up 15-20 times & i have to press cancel quickly or it shuts down. i think it pops up when i move the cursor. i tried antivirus scanning my mac but nothing showed up

my Computer OS is Mac OS X & my Browser is Firefox
I tried the start button & it doesnt seem to be stuck.
The antivirus i have is Intego File Guard X5
my version of Mac OS X 10.4.11
i also tried Resetting PRAM and NVRAM

There are no known viruses for Mac OS X, but malware and trojans, which could exploit your computer. But they are few and hard to get, if you don't install anything the porn site of your choice recommends you or use illegal copies of iWork or Photoshop.

Have you actually waited til the countdown was over and the computer shut down?
Have installed any haxies, to quickly shut down or restart your computer?

Are you running Firefox 3.5? Did you visit any naughty websites under Firefox 3.5? There was a known bug in Firefox 3.5 where if you visit a bad website, an attacker can take control of your computer. When you open Firefox, go to Help (in the taskbar) then click on check for updates. It will update your current version of Firefox.

maybe you have a faulty board, you should check that at your local apple store

if you have a lil time to spare u can try a reinstall that usually fixes mostly everything but if that doesn't do the trick yea take to apple if it still has warranty
