let me tell you my friends
i use eTrust AV almost for 4 years now, from the earliest Inoculan4.0 versions, and NEVER had a single problem with virus on any machine
i just simply love it
it doesn't eat up all the RAM available on yr PC's, updates can be defined to a specific scheduled time - and they release new definitions almost every day (not like weekly updates from MCfee

) and the engine is excelent

i once installed a trial version of Kerio mail server (witch supports eTrust as the mail store scanner and i couldnt select it properly cause the antivirus would catch the test virus before the mail server could say "boo" LOL

...
i had to "snooze" the realtime monitor, so kerio could send the test virus to mail store and
then use the antivirus engine
now...that's good enough for me... :P
