Anti-virus software and other preventive measures:

Many users install anti-virus software to detect and eliminate computer viruses after downloading can find or executable runs. There are two ways that a common anti-virus software to detect viruses are using. And yet already the most common method of virus detection is using a list of virus signature definitions. Computer RAM memory content (and the boot sector) investigated and fixed or removable drives (hard drives, disk drives) by files stored on the works, and compare files against a database of known virus signatures' of the data. This method of detecting damage that the user is only protected from viruses that precede virus definition updates are final. The second method using a heuristic algorithm based on normal behavior is getting the virus. This method is the virus that anti-virus security firms have not developed a signature to detect capacity.

Some anti-virus scan that well as a common way to send and receive e-fliers 'mail' as open files. It 'is known as a practice on access scanning anti-virus software. "No change hosts software inherent ability to spread viruses. Users should update their software regularly have security holes. Antivirus software needs to review periodically updates for the latest threats can stop.

You also can reduce damage due to viruses and (operating system made to backup data) is different media, the law (most times) can be kept outside, is not only accessible for reading or other reasons, such as using different file systems. Thus, if data is lost through a virus, you can start with backup (which recently preferably) should be made.

Optical media such as CDs and DVDs if you stop a backup session, read it - becomes not only can be affected by a virus (if CD / DVD from one or a virus infected file was not copied).
