Or at least those messages sent by friends. Unbeknownst to your friend, he could be sending you a link that would lead you to a particular site (under the guise that it was supposed to be a picture of someone you both know) that would get you to download software. When actually, it is a Trojan horse that would automatically install spyware and adware on your PC and easily distribute itself.



It�s during these moments that anti-virus software would be a big help.



Another thing that should not be trusted are games. One such example is a game called Osama. It�s been found that it is spread via instant messaging.



It is spread via instant messaging via a link inviting users to download the game wherein the idea is to pretend that one is catching Bin Laden.



Those who clicked and downloaded the game and BuddyLinks which were able to grab all the user�s contacts in IM and sent the same message link to everyone.



A lot of software could help



Thankfully, there are security and anti-virus software that could extend the coverage protection of instant messaging services.



Zone Labs, for instance, has released IMSecure. It is a program that makes it possible to encrypt messages as well as block hazardous and dangerous URLs.



The anti-virus software of Norton by Symantec has in its feature the scanning of instant messages as well as McAfee. These software programs are able to remove different viruses from any files that were received through instant messaging.



The good thing about the mentioned software is that it works. Based on the tests conducted by PC World, a lot of anti-virus software has been able to catch known worms and viruses that were sent via instant messaging. Scan your registry for free at http://www.registry-cleaners-reviewed.info




However, it is also a fact that there is really no defined anti-virus software program that could one hundred percent prevent all known attacks from viruses or worms.
