If you have a decent internet connection you might want to try an on-line virus scanner. Symantec does this and I believe McAfee does but I don't remember.

Go to Symantec AV center

Click on the Symantec Security Check at the lower middle of the page.

A pop up window will ask you to be sure you really want to do this. There is a Go button on the screen in yellow you will need to hit.

After hitting go another pop up will ask you if you want to do a security scan or virus detection.

Just click on virus detection and let it run from there.

***Warning***
this process is very slow.

Hopefully this will help.
