DrWeb is really good and would my AV Scanner on Desktop if I would use one, which I didn't because of the use of Smoothwall, which acts as Hardware Firewall with AV between the WAN and LAN. I do use CureIt from DrWeb for to scan in an time interval, which is free to use all times because it's a so also called On Line AV Scanner. Only thing is, it need to be downloaded before every use again and again because of Database changes, which is just fine for me.
