I have searched the forums for a situation like mine with no success, so here's my first "help me!" post. : )
I'm running Windows XP and have been infected with Virusbursters, and maybe other bad stuff. The problem is that I can't open most of my programs: clicking on a desktop icon for Adaware or AVG Free or other antivirus software, or most other programs (games, Adobe Reader, the Calculator) has no effect at all: no windows open, no error messages, nothing. I can open folders OK, just not the programs inside.
One exception is MS Word, for some reason. Word documents open just fine. Also, Internet Explorer and Netscape will open from their desktop icons.
If I rightclick on the Windows Security Center icon on the taskbar, and click Open Security Center, a window comes up saying:
Windows cannot open this file:
To open this file, Windows needs to know what program created it. Windows can go online to look it up automatically, or you can manually select from a list of programs on your computer.
What do you want to do?
[radio button] Use the Web service to find the appropriate program
[radio button] Select the program from a list
If I select Firefox from the list, I can open Firefox (though Firefox won't open from its desktop icon), but after the browser comes up, the Security Center doesn't open at all. Rather, another window appears saying:
"[title: Opening rundll32.exe]
You have chosen to open
which is a: Application
Would you like to save this file?
[Save file] [Cancel]"
and if I save it to the desktop, rundll32.exe sits there and clicking on it does nothing. I think this is a useful system file, right, not virus-related? or could it be virus-related?
If I try to run a program from the CD drive (Sims 2), the drive hums and whirs like normal, but then nothing opens.
I also can't open Add or Remove Programs.
I can open My Computer and rightclick on Properties for the C: or D: drives, but if I hit "disk cleanup" a window comes up saying:
"Windows cannot locate the Disk Cleanup program. The program file may be corrupted or may have been deleted from your computer. To reinstall Disk Cleanup, run Windows Setup again."
Also, if I right-click on any file so far, I have the option to run an AVG Free scan on it. I'm doing that now on the C: drive.
We've been running AVG a lot in the last few days because it said we had threats, & have been "healing" them. It's only since yesterday (Nov 25 2006 ~10pm PST) that most of the programs have not been opening.
Since yesterday, upon restarting the C:\WINDOWS\system32 folder opens up automatically. I don't know why, and I've been closing it. I've tried restarting a few times & no change in anything mentioned above.
I have no idea what to do because except for waiting for this AVG scan to finish (20 minutes in and 0 threats found), I can't open any other antivirus software or tinker with the settings to access Safe Mode.
Thanks x 1,000,000 for any advice!
