People are a bit better educated about viruses. Free anti-virus software is easy to download. Microsoft recommends its own Security Essentials, while companies like AVG and Avast offer their own free alternatives. Computer software, in general, is designed with the Internet in mind and is less ...
This is how enveloped viruses leave the cell. In this way, the host cell is not destroyed. The newly replicated virions will infect other T-helper cells and, left untreated, cause the person's T-helper cell count to slowly dwindle. The lack of T-helper cells compromises the immune ...
Computer viruses are just one kind of online threat, but they're arguably the best known of the bunch. Computer viruses have been around for many years. In fact, in 1949, a scientist named John von Neumann theorized that a self-replicated program was possible [source: Krebs]. The computer...

Multipartite viruses are intriguing viral systems because their genome is divided into several segments and each is enclosed within a distinct virus particle. It has long been believed that all of the genome segments must move together from cell to cell to cause an infection. But the new study ...
