Regras para ter um pouco mais de segurança em Sistema Mikrokit é necessario?

Pessoal seria muito prevensão usar essa quantidade de regras em um RB 750G ou 450G, logico que algumas destas regras creio que não deva mais esta funciionando.

Agora digamos que seria uma boa usa-las qual seria o desenpenho no processamento destas RB's?

Na Minha Humilde Opinião é Gambiarra...
O Provedor não deve Influir bloqueando essas pragas pro usuário final a nível de Firewall, além de gerar processamento em sua rb você pode acabar prejudicando outro serviço com essa BlackList, as regras de Acesso a sua rb pode até ser valida, mais essa de virus/Spyware não valem a pena (Minha Opinião).
Incentive seu Cliente a Usar Adblock/FlashBlock, Use a versão do OpenDns que bloqueia grande parte de sites indesejados que já é um caminho nada "forçado".

@stevefox, @Arthur Bernardes concordo em gênero, número e grau com vcs.
@ccbsumare, eu investiria em algumas poucas regras de firewall para proteger o seu equipamento, evitar o acesso específico a sua RB nos serviços nela rodando, ssh, Winbox, HTTP, etc. Bloqueando todos os pacotes vindo de qualquer lugar que não seja sua rede de gerencia em direção a sua RB.

Do resto, cada um planta o que colhe, se o cliente entrou em um determinado site, ou clicou em um determinado link, ou sei lá o que, não é problema seu. Alias, deve existir uma regra no seu contrato com o cliente que deixe claro que a empresa (vc) isenta-se de quaisquer responsabilidades pelo mal uso do serviço de SCM por parte do cliente, seja para se auto-prejudicar e/ou prejudicar a terceiros, voluntaria ou involuntariamente.

Ok pessoal obrigado pela opniões.

Abraço
