Worm.Viking Description

Worm.Viking is a malicious worm parasite that spreads through computer networks. Worm.Viking is designed to make duplicate copies in different locations on your machine. That’s why it may appear very difficult to remove Worm.Viking manually. Once inside your computer, Worm.Viking will embed itself into the processes of Explorer.exe, Iexplore.exe and others. Worm.Viking may also do weird things to your computer, for example change your speaker volume levels. Worm.Viking may also tend to send its own copies to other users in your network.
