Avast Scan Results

Hello There

I recently downloaded Avast Antivirus 4. I'd read primarily positive reviews for the software and am 3dys into my trial. Well, I did a very thorough scan yesterday and had some results that worry me a little.

Can some please help me figure these results out?

Result:
