Malware Removal Help - logs posted

[thelisma]

My parents - in their 70s - have been having PC trouble.  Their machine is a Sony VAIO running Windows XP.

I installed AVG 8.0 and it promptly found several trojan horses:
Generic12.xxxx
SHeur2.GRY
Downloader.Generic8.HPC
FakeAlert
BHO.GSS
Vundo.DM

...and two worms:
Worm/Autoit.DEG
Java/ByteVerify

I quarrantined everything AVG found.  I couldn't figure out how to make AVG Free output a log file...

Following the instructions posted here I performed the following:

Windows Update was turned off, re-activated it.

XP was at SP2, updated to SP3

downloaded and ran CCleaner, SUPERAntiSpyware, Malwarebytes and HijacThis as instructed

verified JRE was at v6 Update 11

I'm attaching the requested logs.

I suspect a large part of the problem is their grandson (my nephew).  He was visiting all kinds of sites that could have contributed to the problem.  He has now been banned from their PC.

Thanks in advance for your help,

meant to add: they use MSIE exclusively.  I just loaded Firefox onto their machine and am in the process of moving their bookmarks over.

Then I'll delete their IE desktop icon...
