Some files won't open, HELP!!!

I just used AVG anti virus to get rid of a whole lot of viruses and everything seemed to be fine but now some of the things on my desk top such as Winamp and my MSN won't open. A message comes up and it says windows cannot find the program file and then it tells me to make sure I typed the name correctly and try again. I tried right clicking on it and then selecting the Run as... and the it opens. I'm a little worried that I deleted something important when I got rid of all the viruses. I'm not very good at this whole computer thing and I would appreciate any help or suggestions that you have. It's driving me nuts!!! P.S. Sorry this post is so long. THANKS!!!

Hello compgirlie!

You can start by seeing if the programs will start by going to Start > Programs. If you can click on the icon and start the software then great! Delete the desktop icon and create a new one. If it still can't open, go into C\program files, then into the folder of the software that you want to open. Look for the program's .exe file and doubleclick it and see if it will start that way.

And don't about the post being too long! The more information you give, the better!

 

I tried your suggestions and still no luck, thanks for the tips though, if you can think of any other things to try please let me know, thanks a bunch!!

 

And what operating system are you running, please?

If this is XP, download http://www.dougknox.com/xp/fileassoc/xp_exe_fix.zip

Unzip, and doubleclick the file.

It will repair your file association for exefiles.
Subsequently reboot, and see whether that helps.
