Desktop access uanavailable

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.

Are you still able to open the CIS gui ?
can you check all the logfiles and see if Defense+ blocked something ?

Also check the Firewall and Antivirus logs please…
