Written by a programmer or acquired by a criminal, an e-mail virus is a piece of computer code spread via email and designed to run on any computer.
Occasionally, the code is nested in an attachment and installed after the victim opens it up.
Once it gets its hooks into your computer, the virus can scan word documents, spreadsheets and address books, on the prowl for other active e-mail addresses to target.
For some victims, the telltale sign of a computer hijack is when the confused e-mail arrives from an estranged ex.
If the software has lapsed, its mandatory that one should install antivirus software from a full-service company that offers free updates with the program. If the virus is still present after running virus removal and scanning programs, we might have to reload the entire system.
If we wish to keep our computer and personal lives free of complications, experts say the most important piece of advice is to read our electronic mail with a healthy dose of apprehension.
