this is an HKEY local machine > software key issue,, you have left trace files on the PC,,
PC CILLan is an antivirus software from everything that I have seen ,, I have a copy somewhere,, never installed, using AVG,, but that is me,,
their are still references on the PC to look for specific paths to the PC cillan software,,
clean em up, issue resolved,, however, You may have caused a larger error with corruption with the install of the second antivirus,,
even after cleaned up ,, you may still experience crashing,,
