So I was trying to download Four Walls Survival PvP map for my server (This is NOT server advertising). But when I was playing in the map an antivirus popup appeared and then all the screen got covered with "FBI signals" and stuff like that. I think that it's a malware thing that takes your info and passwords, or something like. It has blocked my main administrator windows account, also. If anyone knows how to get rid of this please help! I'm bad with all this technical stuff... I have a HP computer (not laptop) if that helps. It runs on Windows XP and its annoying, it keeps popping up when I'm trying to use the Internet and open websites. Someone please help me I'm so scared!!!!!!
