The crooks behind the GuardWWW virus aren’t very good at naming their badware programs---who thought InSysSecure, SysDefence, and TheDefend were good ideas for names?---but they do have a knack for creating super-obnoxious programs that are hard to get rid of. GuardWWW is more of the same: annoying scareware tactics, phony scans, and manipulative pleas for free money. Fun stuff. It enters as a trojan, burrows deep into your computer, and changes your registry settings. After that, it starts sending its horrible GuardWWW pop-ups, which try to fool you into thinking your computer is infected. Then it starts asking for money for “Realtime protection” it can’t deliver. Don’t feel like getting scammed today? Let me show you how to uninstall GuardWWW for free.
