unable to start scan.there are no more endpoints available from the endpoint map

Hi having failed to use McAfee registered software on a clients machine I have returned home with said laptop to remove what I suspect is a rootkit virus. I downloaded and installed avast using safe mode and tried to start a boottime scan having encountered the above error when trying a realtime scan - the system is totally unresponsive when in normal boot mode.( windows 7 service pack 1…) this also fails ie the boot scan does not start on reboot any ideas solutions?

I am currently creating a boot iso… seems to be taking forever…

free removal help is done in viruses and worms forum section … a removal expert will assist you there

the error is most likely because you now have two AV installed :-[

Did you remove McAcrap completely (using the tool) ?
If not, please do so and perform a clean installation of avast.

Removed macafee as soon as I could

Yes, but did you use the tool ?

After removing McAfee try to install avast in normal mode.
