I know that I have a virus because I can get online in safe mode but not while in regular mode. But I can’t even open Avast because I get the error in the following screen shot…
I am sorry to hear that you are currently having a problem; have you just downloaded/installed avast and then immediately got this error?
The “side-by-side” component is associated with the Vista Windows Resource Protection (WRP). You may have a corrupted the component
Please install Microsoft Visual C++ 2008 SP1 Redistributable Package
Also, if you search for side by side, there are a lot of results explains different aspect of the problem.
If you could give us a bit more information about your computer too, including which version of avast you have, if you have any other software then we should be able to help you.
