While some minor changes may occur over time, this is how updating manually should be done with VIPRE: Go to Updates, Account, About VIPRE, Support, Threat Definitions, Load. Now open the file you just downloaded here. The process may take a few minutes. VIPRE Business definitions can ve downloaded on the Author\\\'s link above.
