Sophos Free AntiVirus for Tiger PPC

Not sure if the forum is aware of this (just saw it on MacUpdate) but Sophos, from what I know a reputable PC antivirus software, has just released a free, real time scanning version of their AntiVirus software for both PPC + Intel Macs running Tiger 10.4 + above. "http://www.sophos.com/products/free-tools/free-mac-anti-virus/". I have just installed Sophos (there is even a "Sophos remove" icon in the Applications folder in case I don't want it), got the latest virus definitions, now scanning all the files + folders on my main drive to make sure that everything is OK. The software puts an icon in the menu bar, which when black in colour is constantly protecting my computer. Before installing Sophos I completely uninstalled ClamXav 2.0.8 because 2 antivirus programs often conflict with each other. Just thought I would let the forum know, interesting to hear your opinions. I will report on any problems, my general experience with Sophos. Ken.
