Today, after I turn on my computer, I get a pop up message saying that I am infected and that I should download some software that claims to fix the problem. At first, I am surprised as I try to be very careful when I am online, but I suppose they found a way to get on my computer. So, I update and run the software that I have which are AVG Free 7.5 and Ad-Aware 2007. I ran Ad-Aware 2007 first and it found a bunch of stuff that I deleted. Then I ran AVG Free 7.5 and it found nothing. I then Explored the Start menu and found some folders that I knew shouldn't be there so I deleted them, but in the Program Files folder there is a folder called Video ActiveX Access. I am very certain that this is the source of my pop-ups and what-not, yet when I try to delete the folder and its contents I receive this message:
Cannot delete iesmin.exe: Access is denied.
Make sure the disk is not full or write-protected and that the file is not currently in use.
These are the contents of the folder:
iesmin.exe; imsmain.exe; iesmn.exe; imsmn.exe; iespig.dll
I then check the Processes in the Windows Task Manager to see if any of them are running and all 4 iesmin.exe; imsmain.exe; iesmn.exe; imsmn.exe are running.
Subsequent scans with both Ad-aware and AVG come up with no issues or infections.
Now I don't know what to do other than consult the experts at Bleeping Computer.
I should also note that none of this seems to have an effect on Firefox.
