Ok, here's the story: I just got a friends pc and when I click on any of the desktop icons, i get this message:

"Windows cannot find [insert the name of the file that I try to open here]. You may have typed the name incorrectly in the run dialog, or another open program cannot find a system file. To search for a file, click the start button, and then click Search."

First thing that I thought about was a virus. So I took out the hard drive and slaved it to my pc and ran a virus check. I found two viruses: w32.annoying.worm and w32.yaha.f@mm.
I've sinced deleted the files infected with these viruses through the NAV wizard.

I put the hard drive back into the original pc, and I'm still getting the same message. I hit CTRL-ALT-DEL and noticed that only the explorer program is running, and the systray.exe is not open. How do I get this file back? There are no backups for this pc, so I'm kinda stumped on what to do.

Oh yeah, I've used the ME boot disk that I made for another pc a few months back, and still no luck. I hope i gave enough details, thanks.
