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.
