[quote user="muskiefan"]I am using AVG on this computer, and it is not blocking those sites. AVG can do some strange things, though. If a file becomes corrupt, for example, AVG can fill up an entire hard drive defending the computer against the corrupt file. I have seen it happen.[/quote]
AVG freeware has it flaws and is not perfect. Is OK for an average user.
I am using AVG-Pro and have known it to be very reliable. Therefore, I take it very serious when it blocks those sites b.o. malware. Malwarebytes/Anti-Malware is meanwhile blocking these sites as well.......
