Hi I'm not sure if I'm in the right place so have posted in another part of the forum as well, so apologies for duplication. Anyway, my Norton picked up a "threat" and suggested I reboot, which I did. I now get a message that says: "lsass.exe The apllication failed to initialize properly (0xc0000005). Click OK to terminate the application" When I click OK, the screen remains black and doesn't go any further. I'm guessing that this is a virus of some sort so have tried to go into Safe Mode to remove it but on the boot screen it goes no further than: multi(0)disk(0)rdisk(0)partition(2)\windows\system32\drivers\agpCPQ.sys So I'm stuck! Where do I go from here - any ideas? Thanks!
