Summer 'parasites' indicate new virus trend

August 19, 1998 Sophos Press Release

Sophos responds to parasitic virus comeback with new emergency identity service.

Parasitic viruses are making a comeback having declined in popularity over the last twelve months. The most recent viruses to strike, CIH and Marburg, mark the re-emergence of parasitic types after they had virtually disappeared from Sophos's virus reports. In order to minimise the threat to users, Sophos has set up an emergency response service to provide early notification.

The recent CIH virus, which paralyses the start-up mechanism of PCs, is ranked the fifth most common virus in Sophos's July league table. The Marburg virus, which struck in June, was the first widespread parasitic virus to be seen in several years. By attaching themselves to .EXE files, such viruses are quickly and easily spread.

"Users shouldn't panic unnecessarily about this summer's outbreak of parasitic viruses," said Paul Ducklin, Head of Research at Sophos. "Our new emergency response service will ensure we minimise the impact of this new trend by making virus information as accessible as possible. The parasitic comeback does, however, suggest that virus writers are finding it easier to create new problems with old viruses."
