Computer Viruses

Computer viruses bear more than a passing resemblance to their biological namesakes: they usually reproduce by inserting their code into legitimate programs, much as biological viruses insert their genetic material into a host cell, causing it to be reproduced. They spread quickly between today's highly connected computers, which run similar operating systems and programs, much as colds and flu thrive in dense populations of genetically similar humans.

There are other, more subtle similarities. As in nature, computer viruses spread most rapidly before they are detected and defences ban be mobilised against them. The most widespread viruses are rarely those that incapacitate a computer quickly, as 'killing' the host stops a virus from continuing to multiply and spread.

Within this biological analogy, anti-virus software plays a similar role to an organism's immune system and up-to-date virus signatures are similar to vaccinations. Just as vaccinating the majority of the population against a virus such as polio prevents an epidemic, computers gain 'herd immunity' from a threat if a suitable majority have anti-virus software that can stop it.

ESP Armor

The latest in speed isn't actually a part - it is what the company can do to your parts. The ESP Armor finish is an optional process offered on all new crankshafts, rods and assemblies purchased. The superclick ESP finish allows oil to glide effortlessly along the part, reducing running friction, improving oil shedding and lowering oil temps. Most important, that equates to mare power and torque. ESP strengthens the part by reducing microscopic stress risers in the surface of the part and inhibiting corrosion/ As a result, a one-year limited warranty is included on any standard-weight forged 4340 crankshaft or standard-weight H-beam rods finished with ESP Armor.
