Click here to download FindnFix.exe (2K/XP only!) by freeatlast. Double-click on the FINDnFIX.exe and it will install a folder called FINDnFIX on your system. Go to that folder and double-click on !LOG!.bat. The program takes a few minutes to collect the necessary information. When done post the contents of Log.txt in this thread.

hey, i tried that fix program, it loads but then its been on for about 5 minutes and still says 'searching', i dunno what do?
Post #4
Do this then try it again. Could you click here to download CWShredder by Merijn Bellekom and run it, hit 'fix' as opposed to 'scan only'. If you already have CWShredder, click 'Check for update' and make sure you are running version 1.59.1 Reboot when done.

Click here to download Ad-Aware and install. Before scanning click on "check for updates now" to make sure you have the latest reference file. Then click the gear wheel at the top and check these options:

General> activate these: "Automatically save log-file" and "Automatically quarantine objects prior to removal"

Scanning > activate these: "Scan within archives", "Scan active processes", "Scan registry", "Deep scan registry", "Scan my IE Favorites for banned sites" and "Scan my Hosts file"

Tweaks > Scanning Engine> activate this: "Unload recognized processes during scanning."

Tweaks > Cleaning Engine: activate these: "Automatically try to unregister objects prior to deletion" and "Let Windows remove files in use after reboot."

Click "Proceed" to save your settings, then click "Start", make sure "Activate in-depth scan" is ticked green then scan your system. When the scan is finished, the screen will tell you if anything has been found, click "Next". The bad files will be listed, right click the pane and click "Select all objects" - this will put a check mark in the box at the side, click "Next" again and click "OK" at the prompt "# objects will be removed. Continue?".

Reboot when done. Rescan with HJT and post a new log here
