I'm completely inept when it comes to computers. I happened to be visiting my parents this past weekend and from the other room heard the sound of an error. When I went inside to look, there were a bunch of error messages on the screen. The first one was telling me that kjoria.exe has crashed- whatever that is. Then I got two errors for a program called dwm.exe. Then I started getting errors about my hard drive needing a defrag, then memory errors, and some peculiar scan started on my screen. Right away I shut it off, and rebooted in safemode.

I immediately assumed this was a virus, and started a virus scan. A few minutes into it, I happened to notice a folder in one of the hard drives that my parents had never seen before- full of numbers and a file cal
led something like mrstub, or mrtstub. After doing some research on that, I found that it was was something that placed itself in my system32 file, and was a virus. After deleting it from system32, and the other file it was in, I waited for the virus scan to finish. When it did over 75 objects which were infected were quarantined, but when I went to remove it told me some couldn't be removed. The ones that couldn't be removed were things that started with HKEY... and something else that i can not remember. After I removed, malware (my antivirus) told me to restart to make the changes permanent, and I haven't been able to start it up since (safe-mode or otherwise).

It will load up until the windows xp screen starts, and then just starts all over again. I wish I could include some of the specific numbers and letters involved in the memory errors, but when the weird scan started, I turned the computer off immediately before i could actually write anything down. Like I said I'm not really good with computers, but my parents are older and would be lost without their lottery numbers and bejeweled.

Any suggestions? Again- no one had been near this computer in over an hour when all hell broke loose.

Thanks to anyone who can help me.
