Very important for the security of your computer are programs that will protect you from viruses. Viruses themselves may not cause significant damage to your computer, although there are also provided. Problem, however, always have the information that your computer – legally or illegally contain. If you have a merchant account for online payments can definitely lose your password or it will fall into the wrong hands. Usually this can be prevented from even the most basic antivirus program, but without it you are doomed. One of the most popular and well-known antivirus programs are Symantec Antivirus, NOD32 and McAfee. Each of them will provide the necessary protection only if you regularly update the definitions. For this purpose, we need to have a legal copy of the program, trust it completely.

You are the desktop administrator for the Graphic Design Institute. You have just deployed new Windows XP Professional computers to all graphic designers. Each computer has a built-in tape drive for data backups. The graphic designers need to back up their own data to the tape drive. You add all graphic designers’ user accounts administrator members of the Backup Operators group on their computers. Then you instruct the graphic designers to create a full backup of all their data every Monday morning. The graphic designers need to back up all of their data once a week. They also need to back up all the changes since the last full backup. The graphic designers want to use a backup method that allows them to recover their data as quickly as possible. You should advice graphic designer to perform a normal backup every Monday. Create an Incremental backup for Tuesday, Wednesday, Thursday, and Friday. A Differential back up only backs up files and folders that are marked as having been altered since the last full backup but does not clear these markers. These markers are called archive bits. Thus, if we performed two differential backups on a file that has been altered since the last full back but not since the last differential backup, the file would be backed up on both occasions. This provides the quickest recovery method as we would have to restore only the most recent full backup and the most recent differential backup.
