The council has signed a deal with ESET that extends its current NOD32 Enterprise Edition licence agreement, which protects the council's 4,500 desktop computers and associated servers against viruses and other malicious attacks.
Dorset considered criteria such as CPU resources used and heuristic security functionality to choose the school PC protection system.
Tony Beazer, senior ICT officer at Dorset County Council, said, "We chose ESET NOD32 because it did extremely well in our tests. One of the main features we like about NOD32 is its light footprint. Our machines are replaced on a four-year cycle, so for the older machines having something that is effective and light on CPU power makes a big difference to how quickly the machines can run."
NOD32 conserves disk space and in memory with the installer just larger than 8.5MB and the application taking up less than 20Mbytes of memory.
"Heuristic capabilities were also one of the features we looked at when choosing our anti-virus solution,"
said Beazer. "The combination of new threats often being exploited before a vulnerability has even been announced, and a large network to update even when we do know about a potential threat, means that reliable heuristic detection is an important aspect of securing the network."
The council had previously suffered from minor virus outbreaks with its original entirely signature-based security system, said Beazer.
