There is an increasing amount of news on rootkits, such as whether a company uses them in Internetcommercial software or if they can be bought to carry out direct attacks on someone. They are undoubtedly the latest craze.

The problem with rootkits is their detection and elimination. Various companies have announced the existence of certain technologies that enable the detection of rootkits in operation, in other words being hidden. The fact that they are concealed makes them dangerous: antivirus detection systems are not capable of finding the files that form part of the rootkit, which means they cannot detect them.

It is a long-standing problem resulting from a relaxation in programming systems. When viruses first arose, the “stealth” technique, which used different viruses to hide itself, was talked about. At that time the most rudimentary virus detection systems searched for file modifications. Consequently, if a file infected by a virus increased the size of the file, for example by 1000 bytes, a program that monitored file changes (or significant changes in the system, such as COMMAND.COM) could quickly warn of the danger.
