Hi there, there is a possible virus break through in Computer Associates E-Trust Inoculate IT 6.0 Exchange Option German on M$ Exchange 2000 German. The CA´s E-Trust Inoculate IT 6.0 Exchange-Option is a antivirus product which can be used to scan incoming email-traffic and background scan of the exchange database. Sometimes a special formed "W32/Yaha-E" virus can break through the incoming mail-scanner. The virus won´t be recognized by the "background" scan-option. The vendor was informed on the 28 of oktober. A fix is available in service pack 1 for the english version. Computer Associates is still working on an german service pack / fix for that problem. Please contact CA to get further information to fix this issue. best regards tigerblue systemadministrator
