I find it ridiculous that many PC owners prefer installing all kinds of trials and demos and “free scan” of programs, and what’s worse – they’re advised to install as many security programs as possible. In my experience, a web scanner sometimes if a better choice. It’s easy to try a dozen of virus scanners, and in many cases they really help to remove malware.
But of course none of these services provide real-time protection. They’re mostly for additional testing and energency cases.
