When two antivirus programs start prowling around, all sorts of problems happen, ranging from program crashes to system lockups. Because these programs typically remain on all the time, they generally load as soon as Windows boots, which means if you install more than one antivirus application on your PC, both programs load automatically and lock up the system before there's a chance to troubleshoot. While it's not recommended to install multiple antivirus programs, you should however make sure you scan your computer with more than 1 spyware/adware programs as others tend to find things that the first one didn't. If you choose this solution you shouldn't however have them both starting up with windows as you will see longer start up times and slower browsing as all these programs are using a substantial amount of memory, you can use the msconfig utility to manage your start up applications.
