"Interestingly, BullGuard doesn't feature much in the major AV group tests such ICSA Labs, West Coast Labs or AV-Comparatives.org. It has only appeared five times in the VB100 list but v8.0 earned two 'fails' in 2008 for missing viruses in the wild list, despite being based on the well-regarded BitDefender engine, so the jury is out as to its current effectiveness against malware.
Simplicity is the name of the game with BullGuard and the new version retains this – it's undoubtedly easy to use. It's also improved and remains a reasonable choice for the home user. But is it as good as Norton Internet Security 2009? No."
