can you help me boot?

[blueprint]

Just got woken up by a phone call from my uncle with a pc problem.

It seems AVG did an update or removed something or did something here, but after it asked to be restarted, windows wouldnt boot.
It comes up with "isass.exe - unable to locate" and also "DNSAPI.dll not found".

I've looked on google, and I can confirm that this is the one with the L, not the i, as one is a virus, and one is legitimate. I need to know how I can get these two files back in the system.

Can anyone suggest anything? I really need a hand.
(this is on XP by the way)

Cheers.
Martin

hmmmm an anti virus program shouldnt have caused an issue like that, he probably deleted something he shouldn't

anyway, a repair install of XP is probably the best bet - try here for more info.
