What Anti Virus does your place use?
We currently use Kaspersky End Point 8 Enterprise Antivirus, and the contract is almost about to come to an end. The facilities that the Enterprise Console in Kaspersky provides is fantastic, and it is full of features. We have had lots of problems with it though, for example - when updates have come through in the past, they've caused machines to loose system files and we've ended up either rebuilding software or repairing o/s.
Sophos is another option, but it's pretty basic and doesn't do too much compared the the facilities in Kaspersky, and Sophos is more expensive than Kaspersky.
What does everybody else use?
