i got 5 viruses in my c drive and it showed in avast software.
i deleted that viruses with the help of avast so does it mean that the files i got in my c drive where virus got infected, that file also get deleted
or
only virus get deleted?
because i installed avast yesterday in my pc and from yesterday my pc getting problem like some of my files are removed from cdrive so they can operate some functions like it cannot delete any softwares or cannot copy and paste the folder etc
If a infection is dedected…
-first option should be repair (avast tries: to repair the file/to remove the virus from the file)
-second option: put files to chest (infections can do no harm there and files can be restored, if needed)
-only delete files, if you are sure they are not related to the OS! You could run into troubles…
As it already happend to you, do you have a cd/dvd of your OS for repairing?

Considering this info: http://www.threatexpert.com/files/runudp.exe.html
you could leave the file in the chest, there it cannot do any harm,
after some time, a fortnight or so, you can safely delete it from there,
Leave it in chest, as polonus said.
Is your system up and running again?
For security you should download and run Mbam: http://www.malwarebytes.org/mbam.php

I think all your questions are already answered in this thread.
If you need further guidance on a specific virus you would have to post more info. (like what has been dedected, which files are affected)
