Virus Checking
A virus is an invasive piece of computer code, usually hidden in executable files posted online, written deliberately to damage computers that run the program. To avoid damage to your own computer system as well as to avoid unwittingly passing viruses on to other users, it is important to regularly use and update virus scanner software.

To protect your computer from a virus:
Run a full system scan each time anti-virus (dat) files are updated.
Scan everything downloaded from the web with anti-virus software.
Check every downloaded file before opening it.
01. Save the file to disk.
02. Run anti-virus software on the selected file.
03. Open the file.
Browse to select the folder or file you want to scan and click the Scan Now button.
E-mail attachments should never be opened unless one is 100% certain as to the nature of the attachment, who sent it, and why it was sent. Unsolicited e-mail attachments, regardless of who the sender is, should be treated as potential virus hazards. Proceed with caution.
It is quite difficult for e-mail messages themselves to contain or be a virus, however attachments to messages may indeed contain viruses. Therefore, before opening any file you should first save it to disk and then run the virus detection program.
Refrain, if possible, from downloading files from questionable Internet sites (for example, sites run by companies or individuals whose true identities are uncertain).
