Hi,
a comment from that forum you posted :
“paid avast internet security has not had any false positives and no threats today. seems to be only hitting the free version.”
This is by far one of the funniest comments i’ve ever read in my entire life,i am about to die of laughter ;D ;D .

One more :
“All the ones that work from Microsoft Security Essentials to Kasperky. They all work. Using a combo of them is good also. Plus your firewall and browser settings/plugins matter. Perhaps even more so than an antivirus program.”
Among the “computer geeks”,it is well known that you should NOT use more than 1 anti viruses,it’s a rule :wink: .Read here why :

My advice is to stay away from the bogus&wannabe computer technician that have no idea what they’re doing.
