Install a free antivirus like Avast and do a system scan, let the antivirus do its cleaning

Are you on a phone or computer?

There are no viruses on WP.

What OS are you on?

If you go into Control Panel, in the top right corner change view to small icons. Find Default Programs. Click the second option, Associate a file type or protocol with a program. There, you can change your file associations back. Find XLS, XLSX, DOC, DOCX, PDF, JPG in the list of file extensions, and re-associate them with the appropriate programs.

However, if you have a virus, make sure that is completely eradicated from your system first. Often times, it is difficult to know for sure that you have eliminated all traces of the virus from your PC. If you're not sure, then the best course of action is to format your hard drive and reinstall Windows from the CD. That is the only way to know for sure that your computer is clean.

Ah, yes true.

AVG Free is a good option as well.
