Many Internet security experts consider the first virus attack on the PC to have occurred in 1986.
That is when the virus releases its attack, spreading when the dead skin cells flake off the body naturally.
They work indirectly by revving up various bodily defense mechanisms to attack the virus.
While no cure yet exists for AIDS, treatments are starting to attack the virus in different ways.
And Hazuda thinks there may be other ways to attack the virus too.
And that, of course, opens up another route to attack the virus.
Existing hep C treatments, based on bioengineered versions of the natural immune system protein alpha interferon, attack the virus indirectly and work half the time, at best, for the most common strain.
The drugs aim either to boost immune response or to attack and inactivate the viral enzymes that hepatitis C uses to replicate, in much the same way that AIDS drugs attack that virus.
Seeing the innocuous virus, the immune system creates attack cells that should, in theory, fight off HIV.
Computer systems at energy firm RasGas have been taken offline by a computer virus only days after a similar attack on oil giant Aramco.
Against an attack minus fast bowler Simon Jones (virus) and spinner Gareth Batty (calf), the Worcestershire openers set off at a high tempo, with Carl Greenidge conceding 32 runs from two overs with the new ball.
No doubt the virus-writers and hackers will find new ways to attack these novel defence mechanisms, just as micro-organisms can evolve their way around immune responses.
In general, the signature-based security products used to defend enterprise networks, such as firewalls, anti-virus products and intrusion detection systems are increasingly blind to modern attack methods, which are increasingly embedded into application data or designed to self-mutate in order to evade detection.
FORBES: Cyberwar Or Not Cyberwar? And Why That Is The Question
These vaccines resemble those used against smallpox or polio in that they use a piece of the target -- there a virus, here a cancer cell -- to boost the immune systems ability to find and attack those targets.
Instead of being a targeted cyberwarfare attack, this malware is simply a run-of-the-mill trojan virus that travels by "sneakernet, " the tongue-in-cheek name for the transmission of viruses across unconnected computers by hand (or foot) in the days before widespread Internet connectivity.
That launches another wave of viral destruction that pushes HIV to mutate yet again, prompting another immune attack, and so on, until eventually the body isn't able to keep up with the virus and pushes out poor, or no more additional antibodies that can neutralize HIV.
