I just bought a laptop with windows 7. I tried to install my Windows Live One Care only to find out that they are EVIDENTLY not compatible!! I get the message-- This program has known compatibility issues… Windows Live OneCare is incompatible with this version of windows. For more information contact Microsoft.” Unfortunately, I already uninstalled my trial copy of McAfee and don't know how to get it back! Please help me!! My computer is unprotected!!!
