I was unable to run ESET scanner this time in Internet Explorer (it was re-directed to an ad site). So I tried going into "Safe Mode with Networking" and got a blue screen with the following message:

"A problem has been detected and windows has been shut down to prevent damage to your computer.

A process or thread crucial to your system operation has unexpectedly exited or been terminated.

If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.

If problems continue disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use safe mode to remove or disable components, restart your computer, press F8 to select advanced start up options and then select Safe Mode.

Technical information:

***Stop: 0x000000F4 (0x00000003, 0x871F68C8, 0x871F6A3C, 0x805FB02E)

Beginning dump of physical memory.
Physical memory dump complete.
Contact your system administrator or technical support group for further assistance."

So I restarted and booted Windows XP like normal, and decided to install Chrome and try to run ESET there. But after installing, every time I try to launch Chrome, I get the blue screen with the same message as above.

So that doesn't look good. Should I still try running Malwarebytes' Anti-Malware?

Thanks,
Matt
