AnswerNot updating your antivirus software makes a number of threats more likely to occur suchs as being infected with malware (malicious code) or being the victime of a phishing attempt and having your identity stolen. If you often forget to update then download a antivirus program that updates automatically. For example, Avast Free Antivirus checks for an update every time the computer boots and at a set time interval while the computer is running. You can download avast at Avast's website for free. Just google it.

Personally, I use Avast Antivirus and recently upgraded to a two-year subscription of their Internet Security program. Speaking from experience with Avast and computers, no antivirus software can delete every virus made at any given moment. Virus definitions (how antivirus programs identify viruses) are updated daily even through the free version of Avast. So viruses can eventually be deleted or as Avast refers to as "quarantined," but needless to say is very effective and highly recommended. See the related links below to download it.
