Hi, I have no experience really with windows 8 but my mother's newish computer has got it and it's gone crazy on her. I think it's a virus and I tried to install hijackthis and it says it can't creat an output file while I try to unzip it. I have no idea what this means. I tried to download winzip and that didn't change anything (if that's stupid and irrelevant it's because I really, really have no idea what I'm doing). Anybody know what's going on?
