Man this was a pesky one, but i finally got rid of the atdmt redirector. I tried all the spyware removers i could get and tried in safe mode with no results. I finally figured it out after a couple of days.
It lies in your hidden temp folder......you'd think that it would be in the cookies folder and could be cleaned out but it's not.
So here's the fix
click start and then run ....Type %temp%
A folder will show up and it will have many temp files in it.
Now you don't see the pesky file your looking for right now, but bear with me. let's do this for fun.
Click on view _-> select all and push your delete button. All these files are gone right? Nope. Now I want you to go to tools and then click on folder options. I want you to go to the view tab and go down to the radio button show hidden files and folders and select it.
Now you should see a file that says altasdmt or something like that. I want you to highlight that file and delete it also.
Now go back and reverse the hidden file types stuff and you should be good to go. I know I finally am
