If not fixed, then the same for extended periods.

I always am suspicious of anti-virus software. I don't think it works well. 

The main difference between cable and ADSL is that the cable folks share a
quasi-local network with a number of other households. If Windows networking
isn't blocked on Windows' firewall, or the router, in theory other people on
that network can browse the files on a user's machine. Likewise, malware with
that capability can have better luck spreading on cable.

Install Linux. ;) Failing that, you need to check into the guy's browsing and
e-mail habits.
