Employees in my office, like most of us, use Yahoo Messenger (besides email) to communicate between each other. Especially to communicate between different buildings and cities. So, Yahoo Messenger is somehow a must in almost all computers in my office.
Today just like everyday at office with my routine activities. Sending files and giving IT support to the users. Suddenly one of the supervisor in Medan (north Sumatra) outlet sent me a message that looks like this picture.
Most of us have heard about computer virus, computer worms, or trojans. They are simply a (usually) small sized computer program, specially designed to damage other people’s systems. Once this virus or worm successfully infects a system, it will try to spread out to other systems to create greater damages. They corrupt files, slows down the system, clone themselves as much as possible, steal data or password, etc. Scary! Millions of losses have been caused by these malwares. In this article, I’d like to share my tips and tricks to help preventing your system from getting infected, or worse, damaged by these malwares.
Malwares evolutes rapidly every day. They got more and more features to get more success rate infecting the target systems. The creators of these malwares also find more and more creative ways to increase the chance to spread around their malwares. One of them, is to trick users with little knowledge of computer systems. The trick is by arming their malwares with the innocent look. Yes, they made them looks like the files or directory people would click everyday. They will try to mime many common files found in everybody’s computer, ie. image files, spreadsheet files, directories or folders, etc. All by simply using the same icon the system used to display our files or directories. If people clicked these “innocent looked” malwares, then they are going to be executed in the system. Which will trigger the infection. But what if we can identify these impostors just by looking at them? It would be cool right? Errr… no?
