Hello. I am currently researching anti-virus options for a new computer build. I've been told that Nod32 is among the best out there, and I'm interested in perhaps using v4 when I get my new rig together. One thing I'm worried about, though, is that Eset's virus threat encyclopedia has no entry for the Win32/Vitro rootkit/virus. I'm unsure if the stories I've heard are exaggerations, but Vitro sounds akin to the viral apocolypse. Apparently it can infect without user input, corrupts files wholesale, and requires an OS reinstallation to get rid of it. Plus, some folks at the Avast forums report the virus somehow surviving reformatting of their drives! Does Nod32 currently defend against this threat? Additionally: I plan tp use my computer to play games regularly, and will likely be interested in using Valve's Steam client. According to Valve, Nod32 conflicts with Steam and both cannot tolerate each other. Does anyone know if v4 has remedied this issue? Thanks.
