I tried to install Regclean 2009 but comodo warned and deleted the file c:\Program Files\Regclean\TCL.dll .
The reported threat was “Backdoor.Win32.Rbot.~LR@1477421”
After this all the icons on the desktop disappeared and no shortcut can be created on the desktop.
When I clicked “refresh” button on right click/ desktop, I got the error msg:
"c:\documents and settings\sridhar\Desktop refers to a location that is unavailable "
Please advise.
