oopuhnpkpjv.sys help!

I'm trying to fix my buddy's computer here. The problem is that it has got to the point where I can't even boot up the computer. If I boot in safe mode it gets hung up on this file (oopuhnpkpjv.sys) which is in the system/drivers directory. How do I go about removing this if I can't even boot to windows.
It's a dell inpiron 350.
Is there a way to boot to dos?

Thanks in advance

 

I tried a boot disk for dos and it wouldn't recognize my boot device for some reason. I will try though....downloading as I type.
Thanks.

 

No boot device available. Although the CD drive is recognized in the bios.

 

OK, I've figured out that I can boot the computer with a USB stick. Can I somehow set up the avira program to run off of the stick? Which file from the link above do I use and how do I set it up?

Thanks,

 

OK, I've ran aviva off of my USB stick, found and renamed/deleted a bunch of files (mostly downloaded music files). It still won't boot past this OOPUHNPKPJV.SYS file. Any other suggestions?

 

Got it figured. I ended up finding a partition on there that I did a clean install of windows on. Hooked up a second HDD and moved everything they wanted to keep on to it (scanned the files first). Then formatted the original HD and did another clean install of XP onto it. Should work good. Thanks for the help

 

which scans would you recommend?
