I heard you can block hosts, also, if there's one person who's particularly giving you trouble. There's someone in my area who constantly gives out these 106.8 KB files, and I think they're either ads or viruses. The strange thing is that no matter what I enter in the search section, there are always 106.8 KB files popping up with the exact same name. I'm starting to wonder if someone has a program that changes the title of their files (or ads, or viruses, etc.) to whatever someone is searching for. Do you know if such a program exists?
