A virus is a computer program written by someone, with the presumed intent of spreading and causing grief.

Like a human virus, a virus makes the infected computer “sick”: it causes poor performance, crashes, lost files and data, or more.

Just as you can copy a file from one disk to another and have copies on both disks, a computer virus is in part defined by its ability to make copies of itself.An offline scanner is simply a complete anti-virus and anti-spyware scanning tool that you download and burn to CD or DVD, or place on a USB memory When discussing computers, memoryspecifically refers to a computer’s RAM, or Random Access Memory.RAM is the memory in which running programs (including Windows itself) and data currently in use are kept.It does a fine job of detecting malware, does so without adversely impacting system performance, and does so without nagging you for renewals, upgrades, or up-sells. In the past tools have differentiated between classes of malware such as viruses and spyware.You would need a separate utility for each: one anti-virus program, and another anti-spyware.

Exactly how a virus does this depends on its type, but can include propagation over removable media such as USB drives, networks, or network-based activities such as user downloads.
