There are several things you can do to avoid viruses and malware from attacking
your computer. In addition, when a file gets automatically downloaded on your PC without Free Malware Protection permission, never access it;
as it's a threat for your PC. Rootkits, by their very nature, can be very difficult to detect, and you
can never be sure that any rootkits present in your system
have been detected or that suspected rootkits have been wholly eliminated.
