Comment:

Two days ago, I linked to an adult website, and it began opening dozens and dozens of windows simultaneously. Now, my homepage gets reset to teen-biz.com....or something like that. Win Min does not respond upon shut down. I have run ad-aware and removed unwanted files, I've removed cookies, removed unwanted favorites, reset web page - no help, it pops back up to teen-biz when the computer is restarted.

After doing some research and running hijack this I found the problem, but am unable to remove the file.

I tried to drag it to the desktop and delete it there, but cannot move the file. I also cannot delete it from it's current location. It is not marked as read only...but as indexed. I think I need to remove it in DOS but don't know how.

The file is in C:\Documents and Setting\All Users\Start Menu\Programs\Startup. Its called winlogon and was created at the same time I started having the problem.

I also have three other winlogon's...all created or modified over a year ago. I am running XP, and have XPSP1, incase this is relevant somehow. Can someone PLEASE help me remove this file.

Read Me and make sure you update either/both products before using them.

Also go and download Cwshredder

Run HijackThis again and place a check in the box next to the following items. Next, close all browser Windows, and have HT 'fix checked'.

You Must restart your computer when you're done.
