The best thing about this service is that they are always open for communication unlike other companies who close off once there's no more work being done. They also provide very good customer support which I really appreciate. It can be expensive at times but since it helps me keep my computer safe from viruses and malware, I don't mind paying up for such protection. There isn't anything I dislike about them because everything seems fine so far. As long as they continue to do what they're doing then I'm happy!
