I have been using AVG since forever. Even though it’s free of cost but I still think it’s one of the best. It easy to use, protects you against viruses, spyware, adware, worms and trojans. It gives you top quality protection that does not slow your system down. They have recently released Avg Anti-Virus Version 8.0.200 Build 1399.
