I got a new Dell computer last month as a present from my parents. They also installed me DSL Internet connection. Then a good friend installed me Torrent software for movie downloading. At the beginning, everything was good. Since yesterday, my Internet connection is slow. Do I maybe have a virus? A friend told me that I should install Ewido Trojan scanner.
I think that you are infected. It is probably the infection with some sort of Downloader or Trojan virus. Its job is to aloud access to hard drive content on your computer to his owner. Those viruses are common on the Internet. I had to reinstall my operating system because of torrent using. That was at the beginning. However, from my personal experience I found out what to use for protection. The protection that I have been using for last six months is combination of AVG and Seagate Personal firewall and I don't have any problems. Use AVG from the Safe mode to clean all viruses from your computer and then, install Seagate Personal firewall. I think that is much better combination then Ewido.
