There are some virus removers on the market such as Norton. One problem I had with Norton was that once Vundo Trojan infected my computer, it was unable to remove the trojan. It informed that a trojan was detected but after multiple reboots and scan, the infection was still present.
Trojan Vundo is basically a trojan that looks like a file that you want. Perhaps a hacker renamed it as a file that you were looking for. After you download this file and execute it, meaning, you double click on the file to install it, the trojan embeds itself into your PCs registry files.
Once it is installed, pop ups and advertisments will appear on your tab browser. You will see advertisments everytime you surf online. Some vundo trojans allow other trojans to enter your computer, and these other trojans will be able to steal your credit card and other personal details, usernames, and passwords.
Since im not much of a techy, I need a simple solution that is 1 click. Just scan, clean, reboot. There are a few good trojan cleaners on the market. Netwire is used by corporations. xoftspyse by the consumer. Netwire is very robust and comes with a registry cleaner that speeds up a slow pc and increases application loading times. It also removes all trojan signatures as it is regularly updated by the Netwire team.
