I eventually want to buy an AT that offers resident protection, but really want to wait until TDS-4 comes out to see what it is all about. In the meantime I was thinking of installing A2 free for use as an on demand scanner. Is it a good AT? Is it comparable to Ewido free? I was also thinking of installing Ewido as well, but don’t like how it need to run a background task/service even if one only uses it as an on demand scanner, although I think I read that it came be disabled and the program can still be used. Anyway A2 looks like it has a very simple interface and that the free versions leaves out real time protection but its on demand scanner is the same as the paid version.
