Symptoms

This symptoms of this detection are the files, registry, and network communication referenced in the characteristics section.

Method of Infection

Viruses are self-replicating. They are often spread by a network or by transmission to a removable medium such as a removable disk, writable CD, or USB drive. Viruses may also spread by infecting files on a network file system or a file system that is shared by another computer.

Removal

AVERT recommends to always use latest DATs and engine. This threat will be cleaned if you have this combination.

All Information

Overview -

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then further propagate the virus. Although many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.
