How to keep computer safer
Even through some viruses and hacker can infect your computer and steel your identety even without your help, using vulnarable system components, software like players and applets, most of them relays on your interaction and trying to trick you to click something without knowing what that really is or what program it comes from, so it's important to know what exactely each alert means and what application is it comming from. In this article I'll touch many of these situations, so reed in.
Get used to system alerts
Each version of windows has sertain set of alerts. In a week of working with computer you will get in contact with most of the system allerts, read cerefuly each of them becuse if you get an alert you never seen before is a reason for consern. For example: if antivirus says your computer is under attack and you have many viruses(in case of AV Security Suit), but you haven't seen this antivurus before and never installed it into your system, chanses are 99 to 1 it's not an antivirus, it's a virus itself! Close the window or even restart computer, if that didn't help, seek professional help.
If you get a message about some component is requaried to watch a sertain content do not agree to install it immidiatly! try first Google it!, find the official site, and then install it from there, this is the most commom mistake when downloading videos from file sharing networks.
