1) Even if you’re careful, you can pick up computer viruses through normal Web activities like:

• Sharing music, files, or photos with other users
• Visiting an infected website
• Opening spam email or an email attachment
• Downloading free games, toolbars, media players and other system utilities
• Installing mainstream software applications without thoroughly reading license agreements

Some computer viruses are programmed to harm your computer by damaging programs, deleting files, or reformatting the hard drive. Others simply replicate themselves or flood a network with traffic, making it impossible to perform any internet activity. Even less harmful computer viruses can significantly disrupt your system’s performance, sapping computer memory and causing frequent computer crashes.

3) Offline backup, according to Whatis.com, also called "cold backup," is a database backup performed when the database is disconnected from the network -- in other words, offline -- and thus not accessible for updating. This is the safest way to back up because it avoids the risk of copying data that may be in the process of being updated. However, a cold backup involves downtime because users cannot use the database while it is being backed up.

In contrast, online backup is a method of offsite data storage in which files, folders, or the entire contents of a hard drive are regularly backed up on a remote server or computer with a network connection. A number of companies provide online backup services for subscribers whose computers are connected to the Internet, automatically copying selected files to backup storage at the service provider's location. This is sometimes called Web-based backup.
