Explorer problem

hey, I'm having a problem with my explorer, I cant access any of the folders in "My Computer" without getting an error message from Windows and then the screen shutting down and going back to the desk-top. Everything is still there as I can view the files through different programs. Ive read other forums and there is talk about photo editors but I dont use any.
Any help appreciated

 

It would help if you could give us your System info as well as more specific info about the error message.With vague info like you have given us,noone can help you.

 

sorry, i got infected with adware a few days ago but got rid of it using ad-aware, Im running McAfee but it hasent found any viruses. This the error signature I get on the error report:

AppName: explorer.exe AppVer: 6.0.2900.2180 ModName: msvcrt.dll
ModVer: 7.0.2600.2180 Offset: 00037fd4s

Im on a Satellite a60 laptop, 2.8ghz, with 512ram, and am on the LAN in my college.
