I installed Nod32 Antivirus v3.0 on a Lenovo T43 notebook. I already had McAfee antivirus and firewall software installed. My computer had been taking a long time to reboot and I thought part of the problem may have been due to the McAfee software. I didn't uninstall the McAfee software before installing Nod32. After installing Nod 32 software, my computer worked fine but after turning off the computer and restarting it, all I can see is the screensaver. The icons don't appear on the screen. Sometimes the taskbar appears but when it does, the mouse is stuck in the hourglass mode. I've kept my computer on for about an hour but it doesn't make any progress. Another detail is that I didn't supply the password for the Nod sofware as I didn't know what it was. We have the 3-computer version of the Nod software. We have three computers on our home network. One computer has had the Nod software installed without a problem, but it is a new computer which didn't have and pre-existing anti-virus software. Any ideas how I can get my computer to boot up?
