I’m having a issue understanding virus protection because I had a virus before and Dell tech team said I needed to reformat pc and I did. I downloaded viruus protection programs and aren’t them programs to remove the virus? Say if I downloaded a song from LimeWire what is the virus protection will do? Are the free AVG protections good or is better buying protections instead of getting a free version? Some sites I go to ads appear when closing, how can I prevent that do I need a spyware protection?
