Nashville Computer Guru Software Recommendation:
We recommend AVG, the free version works good but we do recommend the paid version as contains more features.
Hitman Pro is great as well in addition.
Kaspersky and Dr. Web Cure It is great as well
I feel Norton and Mcafee are useless.
Often rootkits and malware will prevent you from going to certain websites that allow you to download programs that can fix your problem.

I recommend Chrome or Firefox but use Chrome myself.
