MSIL:Agent-BUN Trojan Virus Infection Description

MSIL:Agent-BUN is a new Trojan dropper virus that infects windows operating system severely recently. Being a member of Trojan horse infections, it is different from browser hijacker infection as it cannot be noticed until you run an antivirus security scan on the infected computer. But unfortunately, though some reputable computer security tools are able to detect the existence of the virus they are not powerful enough to get rid of it. They only keep sending you the infection alert but cannot delete the virus no matter which option you click on. The virus always slips into a computer in quite secret way. Computer users seldom find it during their regular usage of the computer. The users will not have any clues on getting infected by the Trojan virus.

There are many possible ways that can cause the infection dropping down to the vulnerable system. When we are on some web sites there exist various contents with words, pictures and videos. If we are not carefully enough and click on some ads links (including picture back links and words back links) we will be redirected to some other sites from the original one. When there is redirection between the two different pages the threats online can get chance to invade a computer. Those computers that have no any security care software will be targeted especially. The ads links are put by the site administrators. They are trying to make profits by promoting some sponsored products or cooperators. By misleading net users to visit the unsafe links or pages they can get profits from the net traffic.
