Is it an evil virus

[34erd]

OK I have been having major problems with my pc, like messages saying IRQL not less or equal, and Chkdsk running everytime I boot up windows. I think this is either a virus or a deleted window file, only problem is that I just deleted all the files in the recycle bin (for disk cleanup yes I know that was stupid). So it may be a virus. I havent ran my antivirus yet, but I ran it before the problems started oucouring. Is there a virus that can shut down my antivirus program, and delete windows files? Also I may have installed the wrong chipset update, could that be cousing problems? I may just reinstall windows, but will that solve my problems? Also will that delete my vidiocard drivers, and will I need to partition and reformat my drive? Any help apreciated I'm running my antivirus program as soon as I defrag my hard drive I'll let you know how it goes

Help

There are viruses that can do all those things, start with the steps in the Sticky, then post the Hijackthis log.

QUESTIONS 101
IRQ_EQUAL_TO_OR_LESS_THAN BSoD's are usually dealing with the HDD and/or drivers of windows (even though the IRQ is used for hardware settings). Does it show the BSoD EVERYTIME you turn on the comp?

The last IRQ_EQUAL_TO_OR_LESS_THAN i ran into was bad memory.

I suggest you run a scan on your memory AND your hardrive. below are a couple links..

http://www.memtest86.com/ <--this one for memory testing (it makes a cd for you)
http://www.hgst.com/hdd/support/download.htm#DFT <--this one for HD testing(makes a cd or floppy)

Ah right-o forgot about that. (I've only encountered it through a bad HDD/win install).

right, either or. A computer i diagnosed 2 days ago with that bsod, memtest brought up 7511 memory errors in the first 5 minutes! But i also see more bad hardrives than i see bad memory. I think you may be right on this one..(especially since chkdsk keeps on wanting to run...)
