Some Computer Virus Facts and Figures
 

Malware is short for ‘malicious software’. It includes viruses and other types of similar programs. Many computer users refer to every type of malware as a virus, but this is inaccurate.

Your antivirus is providing you very little protection against computer virus infections, you probably have infections on your machine as you read this and you should have a professional virus removal every year.

The term ‘computer virus’ was first defined in 1983 by a graduate student named Fred Cohen. It was defined as 'a computer program that can affect other computer programs by modifying them in such a way as to include a copy of itself.'

A computer virus designed to attack anti-virus programs is called a
retro-virus.This action is taken to prevent detection of the virus.

A Trojan is a program that neither replicates nor copies itself, but it does damage the computer or sacrifice computer security in some way. Frequently, a Trojan provides a backdoor for others to access your computer.

The first anti-virus program developed and released by a large corporation was Symantec’s Norton Anti-Virus in 1990.

While many people put Spyware in the same category as viruses, Spyware and Adware typically do not harm your computer in a way that makes it unusable (although many can and will especially if you have enough of them). They can create performance issues and sacrifice computer security. Spyware typically reports your computer activity to a third party; this information might include financial and password information. Adware tends to present the computer user with advertisements.

The world’s first computer virus was created in Pakistan and was called ‘Brain’. It was invented by two brothers who claimed it was to protect their medical software from copyright infringement.

It is estimated that approximately 6,000 new computer virus are created each month. Mostly for financial reasons such as click fraud.

Viruses can’t infect your computer by simply opening an email.

Technically, not all computer viruses are harmful. Some have no practical impact on your computer, aside from taking up a small amount of space. Others can be annoying. Still others can destroy your data or make your computer unusable.

A Worm is similar to a virus and considered to be a sub-class. Worms have the capability to spread from computer to computer without human involvement. A worm might send itself to everyone in your address book, for example.

Scareware or Ransomware is a type of infection that attempts to scare the user into downloading an anti-virus program or sending in money.  Usually this type of infection tells the user they have committed a crime or have virus infections on their computer (which they do of course but it is the software they are telling you reveals viruses....confusing huh?). This program is actually a type of malware. The software often prompts the user to pay money to have viruses removed, tune up their computer or something else. Problem is, once the ranson is paid....your machine is still infected and how they have your money on top of it....
