These software program damage computer systems in many ways from crashing it by viruses whereas Trojans can leak your confidential information on internet to some other user which is doing spy on you. So to avoid such happen to my system I am using Microsoft Security Essentials security from Microsoft and I update it regularly so that it can protect the system from the latest malicious software. But sometime this update create problem while working on computer, it slows down my computer system tremendously and freezes Web Pages while working on internet. so I want to know if there is way through which I can make update on specific time .
