A generic detection is less likely to be effective against completely new viruses and more effective at detecting new members of an already known virus 'family' (a collection of viruses that share many of the same characteristics and some of the same code).The ability to detect heuristically or generically is significant, given that most scanners now include in excess of 250k signatures and the number of new viruses being discovered continues to increase dramatically year after year.For example, you might include your full name, occupation or position, phone number, fax number, e-mail address, and the address of your Web site if you have one.Many people also include a favorite quote, company motto, or short personal statement.
Then, you tell the facility (usually in an "Options" menu) the name of your signature file and it automatically adds it to the note or message template it provides you.
If a particularly prevalent or menacing threat is discovered between their regularly scheduled updates, the vendors will typically analyze the malware, create the signature, test it, and release it out-of-band (which means, release it outside of their normal update schedule).
To maintain the highest level of protection, configure your antivirus software to check for updates as often as it will allow.
To use HTML formatting in your signature, check Use HTML and format the Signature text with the desired HTML mark-up.
If you send messages in text (rather than HTML) format, text characters will be substituted for the HTML markup. The file can contain either plain or HTML-formatted text.
Each time a new virus is discovered that is not detectable by an existing signature, or may be detectable but cannot be properly removed because its behavior is not totally consistent with previously known threats, a new signature must be created.
