What is a Parasitic Virus?
A Parasitic Virus (also referred to as a file virus) is a type of virus that spreads by attaching itself to another program. When a program that is infected with a parasitic virus runs, the virus code runs as well, and the computer’s operating system gives the virus code the same rights as the program. This allows the virus to make changes on the computer, install itself within the computer’s memory, or copy itself.
How to Recognize This Threat: Parasitic viruses are not as common as they used to be, but have resurfaced somewhat in recent years. The signs of a parasitic virus infection are similar to those of any virus, slower performance, pop-ups, new tasks running, changes to web browsers, etc.
How to Prevent This Threat: To avoid a parasitic virus infection, users should avoid clicking suspicious links or downloading attachments from unverified emails, as well as visiting suspicious sites. Aside from training users, endpoint protection is key to keeping your network clear of parasitic viruses.
