Recently I have been receiving a lot of warnings from my antivirus saying that a virus has been blocked. This randomly occurs quite often. I have a feeling that my computer has viruses/malware I do not know about, and was hoping someone could help me. I ran the 7-step removal process about a year ago when my computer got a virus and my antivirus is Avast, and I also have Commodo Firewall. Help would be greatly appreciated.
