You should have active, updated antimalware software on your system at all times. This will help to protect you from even downloading infections such as this one in the first place, and it can assist in eradicating it immediately once it has been downloaded.

Often however, trojan.zefarch removal can only be executed by changes made to your systems registry. There are several places online where you can find detailed instructions for this, but this is not for the casual PC user. This is an advanced course of action, and you may want to consult with a professional before making any changes to your registry, either manually or with a program.
