I need help!!
Windows 7 user here.
Earlier today I removed a virus flagged by Avast and deleted it instead of repairing. A few hours later most of my applications stopped working, I click on the .exe file and the blue circle comes up momentarily, and then disappears as if nothing had happened. Upon restarting I saw that my startup programs are not starting either. I've tried system restore both from within Windows as well as from a repair disc and no change. I've tried a registry fix to re-associate .exe files but this has not worked (besides, some .exe's such as calculator work just fine). Internet explorer works too.
I really hope I can fix this without having to format and reinstall as I have a great amount of work on there (I work in music) and it would mean having to invest in an external hard drive to backup my projects etc
All help much appreciated!
