People are constantly finding security holes (i.e. vulnerabilities) in computer software which could be used to infect your computer with a virus, spyware or worse. When vulnerabilities are discovered, the software vendor typically issues a fix (i.e. patch) to correct the problem. This fix should be applied as soon as possible because the average time for someone to try to exploit this security hole can be as little as a few days.
