The error messages say: "The file (whatever i'm trying to open).exe is infected. Do you want to activate your antivirus program now? The "antivirus" program is just called Windows Security Center. I know that it is fake from previous experience. I CAN NOT DOWNLOAD anything, CAN NOT install anything, ALL I can open is the internet. Do I have to clean wipe my hard drives? If so, how do I do that on a laptop? And lastly, if I DO that, will my OS still be here? I purchased my laptop and do not have the OS disc. Thanks in advance!
