I am looking for antivirus software. I have used Norton before but don't like it because of the annoying popups I get. It seems most every time I go to a website it asks if I want to allow it. Any suggestions on software that I can install and forget about?

Most programs will give some degree of pop up, even if they are simply informational.
Give this one a go.
Minimal popups and it's free: Avira Free Antivirus - Download Best Antivirus Software

I highly recommend Microsoft's product: Microsoft Security Essentials - Free Antivirus for Windows
