Viruses have become the greatest curse of the Internet world, affecting millions of Internet users and communities in other cases. Hackers, spammers, whatever name you choose to call them, these programs called malware, have sown the seeds of fear and doubt in the minds of Internet users in general.

Help prevent viruses, worms and other malware infecting your computer. Explore the new files and emails, and periodically checks the files and existing folders abnormal behavior. Computer viruses are a disease that every computer user is sooner or later. In fact, viruses are just one example Group a set of programs called malware trouble. Types of malware include viruses, like their biological counterparts, which are programs that infect a computer (by various methods) and then spread to other computers when infected files or disks exchanged, Worms are like viruses but are carried on the Internet and can spread from one computer to another by themselves, without a user to facilitate the process of giving someone an infected file or disk, Trojans, named for the Trojan horse of mythology, these are programs that claim to be harmless and useful but in fact do something sinister, like plant a virus on your computer, Spyware that is not but software that records your online activity and monitors keystrokes and sends this information to a remote server, Dialers are programs that are downloaded on the computer from a webpage, then stealing money from you by calling the phone numbers in rate of premiums, the kidnappers are small programs which are often infiltrated your system through e-mail or Web browser, which then hijack your browser settings (eg) changes in design of default home page.
Viruses, worms and Trojans that are a nuisance, while the spread of their infections, but most of them also are doing something else, known as the payload. The payload can be a somewhat innocuous, like displaying a message or changing the system colors, or may be something destructive as deleting files or formatting the hard disk. This burden is often not activated until the virus has infected the computer for a while (which gives the opportunity to spread) So the fact that you have not noticed anything unusual does not mean your computer is not necessarily healthy.
If your computer is infected, if the load is harmful or not want to get rid of the virus as soon as possible to eliminate the risk of spreading to computers on your friends and colleagues.The only sure way to get rid of a virus is to use anti-virus software. Some Viruses can be removed manually, but different viruses need different removal methods and when you find the correct procedure, an antivirus software already have done the job.
In some cases, the virus may not be able to cleanly remove a virus from a file, the file may allow damaged and unusable. In this case, your only option is to restore a healthy copy of the file from the software installation disks or a backup.
A backup system good is by far the best protection against data loss due to the action a virus (and other disasters). But we must work hand in hand with regular use of a scanner virus, otherwise clean backup files could be replaced by infected before their system has a virus.It is better to prevent a virus that infects your computer first having to remove it once did. Therefore, it is worth paying attention to virus prevention measures.
The best all around system protection is to install anti-virus software and allow access (this is usually enabled by default.) This work silently in the background, checking files in search viruses. You need to worry until a virus is detected and triggers the alarm.
However, we must remain cognizant of the need for protection against virus as far as remember to update your antivirus software regularly. These days, daily updates are not too often! New viruses appear constantly in the scene, and despite the claims of software vendors, virus scanners are not very good for detecting viruses that do not know. Update is the only way to keep antivirus software on a high performance, ensuring that he knows and can detect all the latest threats. Trusted and reliable anti-virus programs are McAfee, Norton Anti-Virus, AVG, PCCillin, Trend-Micro, and many others. Anti-virus programs work on continuous updates of anti-virus definitions and thwart new viruses by managing to keep one step ahead of them.
