Thanks for the feedback. I've heard great things about Malwarebytes and SuperAnti.
Here's a link to cnet to download the free version of SuperAnti. They don't seem to push the pay version there.
SuperAntiSpyware Free Edition - Free software downloads and reviews - CNET Download.com
This site also gives a brief synopsis of the application. Also, on this site, I noticed the download ratio of SuperAnti to Malwarebytes is 3 to 1, for whatever that's worth.
So Curlyben, I read that Spybot uses some older technology and doesn't have as many updates as SuperAnti and Malwarebytes. Have you heard anything about that? Also, it takes me 2 hours to run a Spybot scan, vs 45 min to run a SuperAnti (full) scan. Your thoughts?
