After bootscan erased one virus some applications doesn't start!

Hello,

I installed avast home edition to one of my friend’s computer.
After installation it asked me if I want to schedule a scan on boot (or something like it).I clicked yes.And later the computer asked to restart I clicked yes again. When it restarted bootscan appeared and it started to scan the files in the computer.

Later it found a virus like “win32.xxx?”. It asked me what to do. I choosed “erase”. The program erased it and continued to search. After it finished searching I saw the indication that program is preparing for normal start and starting windows.But this screen freezed and did nothing for more than 5 minutes. After that I closed the computer from the main button. When I started it again I could see my old desktop but when I clicked the shortcuts on it a warning appeared saying that these programs like iexplore.exe can not be started. I tried for other programs but they were not starting also. I could open the other files but could not start the “exe. files”. I thought this roblem maybe because the wrong installation of avast. I tried to uninstall it but “program add and remove” application was not working too.

I opened my computer in safety mode and managed to uninstall avast but the problem was still there. I thoughed to make a “system restore” and hardly managed to restore it to a previously recorded time. But the problem still there. I can not still reach any other applications like “msconfig” or “regedit” from run command. :-[

My friend says he also has no rescue disk to reinstall the OS.
Can I solve this problem without reinstall the os?
What could be the reason for this? The file I erased or shutting down the computer unproperly?
And how can I solve this problem?

Thanks.

You could be still infected. But you can’t restore files you’ve deleted. The safer is send to Chest (Quarantine) for further analysis or even restore.
He need an OS CD to repair (overinstall) or restore system files (sfc command) or install again.
At least, do you know the exactly virus name and the infected file name/path?

Unfortunately I don’t remember the virus name or the file path :-[
As I understood from your post it maybe because I erased an important file with the virus which causes my new problem :

But my friend has no os cd >:(
Can I restore the system files as you said? (cfc command ) you said .
How it works?(In a computer which says “it doesn’t start” to all applications"
Maybe in safe mode?

Thanks…

Not if he does not have the CD.
