As an avocation, I trial various security programs, especially AV's, FW's Anti Spyware, AT's and the like. Occasionally I end up challenged by some of the situations I create in the process. Specifically, I must have been trialing KAV 6 beta recently and due to some system error that ocurred while I was doing that, I ended up with KAV 6 as an aborted installation which I can't remove using Control Panel or any other uninstallers. Using the search tool and registry cleaners, I have removed alot of KAV orphan items. However, I still can't install the current beta of KAV 6.0-I get a message that the program is already installed and terminates the new installation attempt. Could this be due to some residual references to KAV 6 in the Registry? I have not explored that possibility. Also, I was able to install KAV 5.0 Personal and get it fully functional with no problems. I am running XP Home and other programs are not affected. Any suggestions?
