I would recomend that you purchase Norton anti-virus or McAfee. These companies provide free updates available through the internet. You shouldn't have to pay for upgrades. You can uninstall your current anti-virus software by going to the control panel and double clicking on the add/remove programs icon, select the Dr Solomons from the list and click remove. If you cannot find this in the control panel, go to the directory that Dr. Solomons is located in and search for a file called uninstall or uninstall.exe, and double ckilck that. Or if neither are there you might try deleting the entire folder.
