On the Origin and Evolution of Computer Viruses

Trends and industry analysts state that the efforts of the propagators will not relent. Last year marked the first ever mobile phone virus and Bluetooth technology, for example, compounds the threats to security. 35% of PCs in the US are infected while in China and India the rates hit 50%.

Experts in the field of security report the first virus was spread as early as 1981. Fred Cohen, however, wrote in his seminal paper that the first virus was conceived as an experiment on November 3rd, 1983. Since then viruses and malware have plagued and wreaked havoc among computer systems worldwide.

Risks through the Internet

With the advent of such communications advances like the Internet, mobile telephony and Bluetooth (a short range radio technology that simplifies wireless communication among devices such as computers and mobiles. It also aims at quickly and easily connect these devices to the Internet) computer viruses have spread at an alarming rate. The downside to such advances is that where before only a few computers would get infected, now thousands, if not millions, are at the mercy of virus authors.

Early Threats Disable 10% of Computers Infected

In 1987 a large network (ARPANET) used by universities and the US government was infected by a virus. Robert Morris, son of a computer security expert for the National Security Agency, sent malicious code through ARPANET, affecting about 10% of the connected computer hosts – at the time there were only 60,000 hosts connected to the network. The code reproduced itself and filtered through network computers; accordingly, the size of the files filled computers’ memories, thus disabling numerous machines.

An alarming 66% of PCs today are Infected by Spyware and 35% are infected by viruses in the US. Today, an estimated 1.21 billion people (Computer Industry Almanac) are connected to the Internet with millions of computer hosts connected chatting, exchange files, emails and communicating in general. Can you imagine how easy it is to spread a virus or malware?

One anti-spyware developer, reports that the infection rate of malicious spyware at companies is approximately at 7% and adware appears on an incredible 52% of machines. 3 to 5% of enterprise machines had keyloggers. At homes, the percentages are much higher. The same anti-spyware developer reports that 66% of the PCs scanned by its online tool were found to be infected with an average of 25 spyware entities each. If one were to define cookies as spyware than the rate will shoot up to 88%! Adware was found on 64% of the machines. Viruses and Trojans, reports the company, were found on 7% and 19% of the machines respectively.

According to Panda Software, over 50% of PCs in India and China, for example are infected with a virus. In the US and the UK, the rate is 35%. All in all, this means that many people still remain without active protection today.

Anti-virus is not enough

In a study performed by security firm Checkbridge, the company ran 2 million email … Read More
