Unfortunately I got a virus.
AVG found it (Generic2.GNY???) which it then removed but it did something to my windows firewall so that it would not start.

I am running XP Pro SP2 on a compaq presario r3000 laptop

Researching the error messages, I found a post that said the registery was hacked.

MS provides a registry cleanup script to fix it:

I ran the reg file and restarted my pc, and could indeed use the firewall again.
I did a full antivirus sweep and made sure my system was clean.

Unfortunately, since then I am experiencing one very annoying issue:

If I log out and then re-log in again as my user or any other user, it crashes with a blue screen, giving the error

DRIVER_IRQL_NOT_LESS_OR_EQUAL

Error code 100000d1, parameter1 00000008, parameter2 00000002, parameter3 00000000, parameter4 f8357c00.

This does not occur with normal windows startup, only if I log out and then relogin.

Thoughts?

Maybe try to repair the Windows installation, using your Windows CD.

try run chkdsk. some of the irq might have been ruined by the virus. chk might help.
