I remember the day when a Indian called saying all of ours computer were infected with CIH or something. My Dad played along seemingly to know nothing about computers. Then said. “Well guess what my computer is messed up my ***. I work for the ITS Departement of (A University (Not saying the name given it’ll tell you guys where I live)). So go take your scam stuff elsewhere.”
Rule #1: Any company will NOT contact you if their is something wrong with your computer. If their is then don’t take advice from them. They’ll hack your computer till it doesn’t exist.
