Hello,

I have recently switched from Norton Antivirus to Avast because Avast has really
good scores for catching viruses and it works the best on Windows 7. My daughter
recently had a virus on her system while Norton had been running. :(

Avast also has a free version.

So, you are in good shape with using Avast.

Sometimes virus alerts can be false. In other cases some of these blog sites may be
running an advertiser banner rotation and some bad advertiser gets in the mix.

Most times that I have reported virus alerts to blog owners they were grateful and
promptly removed the advertisement. So if you do get an alert and you have the spare
time, send the blog owner an email and let them know.
