Run, cmd not working



I cannot open a command prompt window from the Run dialogue box.

Also cannot get auto updates for my AVG 8.5 AV and Anti-Malarebytes
programmes. IE7 works fine though.

Need some new angle of attack if it's a virus/trojan as I can't find one.
Tried scans in safe mode and with HiJack This I can't see anything obviously
bad.
Intel Core 2 Duo PC with XP Home SP3

any help suggestions greatly appreciated regards IanC
