[Declude.Virus] update virus manual page

[Bonno Bloksma]

Hi Scott,   Could you add the link to the page explaining about the vulnerabilities ( http://www.declude.com/virus/vulnerability.htm ) to the virus manual page at the relevant place? I needed that link and was unable to find it on the site via any other link.   Searching for vulnerability did not produce *any* hit. Maybe that should be adressed as well, as it is a big feature of Declude virus.   Groetjes,   Bonno Bloksma
