Oh dear.... I had a PC with this one a few days ago...
Its a B@stard. Wouldnt let me run Task Manager or CMD
What I did was goto a remote computer, then run a tasklist on the infected machine. endtask the nasty then I was able to go back to the computer to rectify everything that it had done. I noticed these :
Created startup entry.
Created scheduled task
Created Regkey for run at boot
Created Regkey for run at login
localhost was set as a proxy
The process I had to kill was : ljrrsysguard.exe
I have a feeling part of it is ramdomly generated.
