Lately when I boot up my computer I get a message that igxtray.exe has done an illeagal action. I have the choice to either ignore or close. If I click either, Task manager and Norton will only stay open for a second or less and then close. It also closes the game I play on my pc. Any help is GREATLY appreciated. Thank you.

There is a good chance that this is a virus/trojan issue.

Please follow the instructions HERE & then post your log in a new thread in the Spyware, Adware, Viruses and HijackThis Logs section.

If your log is clear then post back to this thread and we can take it from there.

Hijack this won't open, I tried using it already before making the post. It may open for .3 seconds but closes instantlyjust as Task Manager and Norton do, along with other random apllications.

I also checked devices and I seem to be missing a driver, that I know I had 2 weeks ago. Media Audio COntroller is the one that is deemed missing. Any advice you can offer for this?

Try HijackThis in Safe Mode. Definitly sounds like a virus/worm/trojan.

Alright I'll reply in a few days. At someones elses house without my pc. Thanks for following up quickly.
