This could be due to any 3rd party application conflict. Do you have any other malware/spyware application installed?
Please try to re-install the McAfee product from your McAfee account.
Hi Manoj - I'm running SpySweeper v610.157, although it was not launched at the time. One of it's starter services was running. Also, I use ZoneAlarm v93.037 as the firewall, but with the anti-virus turned off to not conflict with McAfee.
This normally happens if there are multiple security software installed on the hard drive . Please run the concerned removal tool for those security software and uninstall the program.
