Help: weird computer problem

[drims]

I have a weird problem I need help with.

Ok it starts when I try to play yahoo chess. I get on , and about 5 minutes of playing chess i get this pop up msg,
"a script in this movie is causin adobe 9 flash player to run slowly, if you proceed your computer may become unresponsive, do you wish to continue with the script"
and if i click yes my comp becomes unresponsive and i have to restart , if I press no and close it, then afterwards my firefox wont open. Instead I get a msg pop up saying'
"firefox is already running but unresponsive, to open a new window you must close this one or restart your computer."
But the weird part is fire fox is closed... Any recommendations?

There's some firefox related process still running, and the system registers it as firefox. If you launch the task manager, you will see it (firefox) still among the processes. You can shut it down there (end process). That should sort the firefox not launching problem. Won't help with the chess, though...

It definately sounds like some program has gone crazy and started using up all your resources.

One idea is to run through add/remove programs off the Windows control panel and uninstall any/all applications that you do not want or recognise that you would ever use again.Uninstall all browser plug ins while your there, it might be time to download their latest versions anyway. Reboot your computer after, and use it again, see if your system slows down.

The next step I would attempt is to boot into "Safe Mode" and try spybot/adaware/antivirus programs again. Some viruses/malware/spyware disable detection from these programs (even with their latest updates). Otherwise off a normal boot you could try "Root Kit Revealer" if the virus/spyware is sophisticated enough to avoid detection.

As a last resort consider re-installing Windows. A pain I know but if you backup/move your documents & save games to a safe location in the end it's like getting a new computer.

Cheers & Good Luck!
