Viruses have friends called Worms and Trojan Horses and a cousin named Rookit They spread from file to file, from computer to computer often by sending themselves to everyone in your network. Some worms need an action from you to get to work, some trick you into it .They take advantage of vulnerabilities in a system to run on their own. Simply opening an e-mail or previewing it can launch these aggressive viruses. For example, Trojan horse gives the appearance of being an innocent game or screen saver, but can destroy files or let hackers in the back door. While a Trojan horse doesn't automatically spread, it still can cause significant damage Trojan horses are often used to steal personal information. Some of these viruses can capture passwords and user names and send this information elsewhere. Rootkit is a smartest one of its kind and it can do anything from slowing down your computer to even prevent you to login and more... A complete rebuild is the only way to permanently eliminate it. |
