OS is XP SP2
Whatever it is is smart enough to recognise any attempt to shut it down.
It prevents any internet download.
It closes taskmanager, regedit and other system level tasks.
MSConfig will run, but it switches from diagnostic startup to selective startup and so I can't get the machine into safe mode.
Adaware will run but won't kill the virus.
I've tried installing the free downloads from this site, but none will install or run, so no HJT logs I'm afraid.
AT the moment I'm at my wits end and am contemplating rebuilding the machine from scratch.
Please advise on what my next step should be, because I'm not even getting to square one on this one.
Many thanks, in advance.
