ClamAV for Windows is lightweight cloud-based antivirus solution, that keeps your PC safe from malware without compromising its performance.
One difference from most of the antivirus competition comes in the program's scanning focus. Instead of grinding through your entire hard drive, it focuses on the programs you install and launch, greatly reducing the scanning load.
And another comes in ClamAVs "ETHOS Protection", a heuristic engine that detects threats based on their behaviour, rather than just signatures. If it detects something nasty then this information is immediately sent to the cloud, so all ClamAV users are immediately protected, even from the very latest malware.
The end result is a very simple and straightforward tool, with nothing complicated to worry about, no confusing options or settings: it just works.
