Computer Virus Accounts For About 7% Of Total Data Loss

Computer viruses: Cause of Data Loss Another threat to your important information provided by a computer virus. It is a synthetic self-replicating computer program that the infection is spreading through the documents and files. Because, worms and viruses have in the number in recent years, it accounts for about 7% of all data loss.

When the system boots from the hard drive or floppy disk, virus is executed and installed its own code into the system. The boot virus may at any disk, read by the system memory. These viruses are the most common of all other viruses. The examples of the boot viruses Stoned virus, Michelangelo, Disk Killer, shape, junkie virus, virus and Ohio. Symptoms? A boot sector virus can cause some problems associated with the boot or data retrieval. There are cases in which the data from disappearing entire partitions or the computer suddenly unstable. The failure to find the start or the hard disk are the common problems that can be detected when the virus attacks a system.
