of course you are very annoyed at the very moment when it takes your computer has an error. this can make you stress. computer error can be caused by several things.because the computer is old, the memory is full, and computer virus attacks. whetherit's a computer virus? kmputer virus is a file or application is ordered to mess up yourcomputer system. so that disruption will occur when you use your computer such ascomputer work to be slow, often to restart itself, until we can not use computers at all. inthis article I will describe several types of computer virus that often affects most of thecomputers in the world.

1. Trojan Horse Virus

Trojan horse in computer security refers to a form of suspicious software that can damage a system or network. trojan name itself is taken from a statue of a horse's name is used to smuggle Greek soldiers to fight the Trojan forces. name of the statue of the horse named Trojan horse. The purpose of the Trojan is to obtain information from the target.
properties of a trojan virus is:
- Trojan is "stealth" (invisible and not seen) in its operations and are often shaped as if the program is a good program, while a computer virus or worm to act moreaggressively by destroying the system or create a system to crash.
- Trojan controlled from another computer (a computer attacker).

the workings of a trojan virus is to smuggle malicious code and damage in a program.




2. Worm virus

worm is a computer program that can reproduce itself independently in the computer system. A worm can reproduce itself by utilizing a network without intervention from the user itself. Worm does not like the usual computer viruses, which reproduce itselfby inserting the program itself on the existing programs in the computer, but theworms exploit a gap which is open keamanaan or better known as vulnerability. There is only one way to cope with the worm that is by closing the security gap that is open, with how to update a patch or service pack of the operating system used with thepatch or the most recent Service Pack.

Common symptoms resulting from the worm is up files that are not known with a weird name. computer hard drive suddenly becomes full so that the performance of the computer becomes slower.




3. virus Spyware

Spyware software is derived from advertising, which monitors the surfing habits ofusers in making the Internet to bring ads to users. However, because the software is less harmful advertising, spyware do it and send the results that he collected to theauthor.

so sometimes our computer sends something to an address unknown to us andsuddenly our internet bills soar.

That's some viruses that often bother us. would be helpful to take precautions before the virus is widespread in our computer. antivirus choose a truly reliable. if necessary use a combination of several local antivirus antivirus for local spread of the virus can be overcome. Do not forget to update our antivirus. our best if not updated antivirusantivirus then we can not recognize new viruses are spreading faster and faster.
