Thanks. I restarted the computer after installing Superantispyware, and now Firefox will open but it takes a long time. Internet Explorer, on the other hand, opens immediately, as do any other programs that I am working with. I downloaded and installed Firefox for the first time the day before downloading and installing Superantispyware. It was working fine and opening fast until I installed Superantispyware.
Is there some incompatibility between Superantispyware and Firefox? I installed Superantispyware and now I can't even open my Firefox browser. I can open Internet Explorer just fine, however.
