I have a friend who unfortunately downloaded and installed Winantivirus pro. I have been able to get rid of most of the program. I've been into the registry and removed every reference to the program; have run Adaware: have run an on-line virus checker (TrendMicro) and run Spybot also. Reinstalled the original antiVirus program (AVG) and everything has been working OK for the last month. However, there is an icon in Control Panel that I can't remove. Any suggestions??

Tell us about the icon.  What is it?  Where is it in Control Panel?

I did reply but must have put in the wrong place.
The icon is a biscuit or donut shaped picture and it is the last item in the control panel. When you pass the cursor over it, the message reads "Winantivirus pro is active on your system" If you right click on the icon you get choice of "Open" or "Create Shortcut"

   There should be a coresponding *.cpl file in the Windows\System32 folder for that item.  Each item in the Control Panel has a cpl file, so if you find the right one and remove it, it should remove its item from the Control Panel.  Instead of deleting the file, I would rename it to have a different extension, just in case you didn't get the right one.  Once you have confirmed that it is the right one, you can delete it.

Hi Ray
SUCCESS !!!  Firstly I looked for the CPL file and could not see anything that seemed to refer to Winantivirus Pro. The only one that appeared vaguely similar was a file called AV.CPL. I renamed that xxxxav.cpl, shut the computer down for 30 seconds, rebooted but the icon was still in Control Panel. Decided to remove the file altogether by moving it to a floppy. Hey, presto, that did the trick.
Thanks very much for your assistance.

   Good.  I am glad that worked.
   I should have said to rename the file so that it had a different extension, not cpl.  The Control Panel looks for all of the cpl files and lists them.
