First things first - with resident AV pgms more is DEFINITELY not better. You must remove, now, one of either Norton or Avast AV's.
Good. For a start you have a vundo infection... so just in case something else is hidden would you rename hijackthis.exe to.. umm... imabunny.exe for the next scan, please?
Now move it from your desktop to a folder in your c: root. C:\
==Please download VundoFix.exe to your desktop from http://www.atribune.org/ccount/click.php?id=4
Double-click VundoFix.exe to start it, click the Scan for Vundo button.
When the scan completes click the Remove Vundo button.
You will receive a prompt asking if you want to remove the files - click YES
Your desktop will then go blank as the process of removing Vundo starts.
When completed it will prompt that it will restart your computer - click OK.
Note: It is possible that VundoFix encountered a file it could not remove.
In this case, VundoFix will run on reboot, simply follow the above instructions starting from "Click the
Scan for Vundo button." when VundoFix appears at reboot.
Post the contents of C:\vundofix.txt plus a new HijackThis log.
Now dl and run these two:
CCleaner:
==Get CCleaner from http://www.ccleaner.com/ - and put it in a new folder. You should aim to keep this one for general use. I set it from the installation checkboxes to only open from the recycle bin. It's neater that way.
Now run CCleaner from the recycle bin rclick menu using its default settings [if you set up CCleaner as i suggested, rclicking the bin icon should give you the Open CCleaner option...]. Select the Cleaner icon, press Run Cleaner.
[For future quick temp file cleaning select the options you wish to use via the Windows and Applications tabs .. Note that CCleaner is also a free registry cleaner. Explore all its options, but skip the prefetch folder cleaning option. That one is unnecessary because windows automatically dumps old unused entries anyway, they can do no harm, and further, if there is no prefetch entry for an app you wish to load then your sys will just be a lil bit slower loading it. And an entry will then be generated anyway.]
Combofix:
==Download this file to your desktop: http://download.bleepingcomputer.com/sUBs/ComboFix.exe
- to run it dclick combofix.exe and follow the prompts to start it. When finished, it will produce a log, C:\Combofix.txt - post that log in your next reply.
A word of caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs, please reboot to restore the desktop.
Post those two logs plus a fresh hijackthis log, please.
