Viruses are potentially malicious code that can attach to seemingly innocent documents or programs.
Some symptoms of viruses include but are not limited to word documents that can only be saved as templates, constant disk activity, or inability to access your hard drive. Viruses can be spread not only by diskette, but by email attachments and through files downloaded from the Internet, so they are much more widespread than ever before. Even if the attachment is from a trusted source, you should scan the file with an antivirus program first. Do not download files unless they are from a known, trusted site. Set your antivirus program to scan files on download.
