Use e Trust antivirus version7.0.405 for last 2 years no problems with a sub. for updates etc for 4 years.
It did an update on Thursday since when its scheduled updates have not been possible with the message "An update of the InoculateT engine for WindowsNT/2000/XP/2003(386) will be used to update the local machine" This is then followed with a message "can't find information on the Innoculate T engine for Windows NT etc on the remote site" "Download unsuccessful"
We had e-Trust pre-installed on one of our Evesham laptops. When I didn't know any better, I paid (ouch!) up-front for several years updates but I don't think we ever got any. Long since uninstalled and gone over to AVG free.
I had the same error message using version 7.0.139, but it now seems to be back to normal. Under signature update options I use FTP, source click here as the first option and the second option is ftpav.ca.com. Can't remember where I found the info originally but they recommended the click here as the better option I think.
