What is "actifed"

Actifed is a G2-generated encrypted computer virus which infects .COM and .EXE files but not [[command.com]]. The virus is loaded into memory by executing an infected program and then affects the computer's run-time operation and corrupts program files.

It is interesting that G2 is a computer virus creation tool written by Dark Angel of the Phalcon/Skism organization. This organization also wrote the " Phalcon-Skism Mass Produced Code Generator" [PS-MPC] which was used in the creation of Abraxas and numerous other viruses.

G2 generates compact, easily modified, fully commented, source code of .COM and .EXE infectors. It also supports the creation of resident and non-resident encrypted and non-encrypted viruses. The PS-MPC has similar use.

Actifed is a registered trademark for a combination antihistamine and nasal decongestant medication used for cold and allergy symptoms. Developed in 1958 by Burroughs Wellcome & Company (now part of GlaxoSmithKline), the product was later acquired by Pfizer, and was most recently sold by Johnson & Johnson. In the U.S., the formula was changed in 2006 due to a change in the legal environment; at the same time, distribution of the product was limited to certain stores. The United States Food and Drug Administration, FDA, lists Actifed as discontinued.
