Bebu,
I'm really surprised to see that nobody else here has contracted the "actulice" bug. There are indeed loads of people who have.
Here's what I did in order to get rid of the pesty little thing:
1) Go to "start"
2) Click "run"
3) Type in "msconfig"
4) Click "OK"
5) Click on "Startup" tab
It's at this point where patience comes into play; the reason being the bug apparently has a different name for each computer it invades. Its particular name on my computer was "pg4ds32m". Since you don't already know the name of it in the listing under your "Startup" tab, you'll have to determine by trial and error which one in the list it is. So what you do is remove the check mark from all of them ONE BOX AT A TIME until you've identified the culprit (but be sure to write down its name). Just start with the first one in your list, uncheck it's box, then restart your computer. If the problem is still there, go to the next one on the list, and so on. You'll eventually find the guilty culprit. Once you do, then go back and put a check mark in all the other's boxes.
Next:
1) Go to "start"
2) Go to "Find"
3) Select "Files or Folders"
4) Type in the name of the culprit that you discovered.
5) When it's found, highlight it and hit the delete key.
6) Also delete it from your trash bin.
Next:
1) Go to "start"
2) Go to "Programs"
3) Go to "Windows Explorer"
4) Scroll down to "Program Files" & click it.
5) In the listing on the right look for the items "over.exe" and/or "pup.exe". Delete these. Also delete them from your trash bin.
That got rid of the little stinker for me. I hope you never have to deal with it.
