Anvi Smart Defender aims to protect your PC against malicious software, such as virus, Trojans, adware, spyware, bots and other threats.

It's a relative newcomer to the anti-malware software scene and users have already noted that it bears more than a passing resemblance to IObit Malware Fighter. It has a very similar interface and also features a "Smart-Engine" although does not appear to be connected with IOBit in any way. Although the developers don't have a physical office, they do seem genuinely concerned with helping users stay virus/malware free as evidenced on their blog and Facebook page, albeit in poorly written English.

There are five function modules: Scan, Cloud Scan, Guard, System Optimization and Update. Scan features a continually updated database which protects in realtime from malware threats. Cloud Scan scans the most commonly infected areas of your compute and uploads them to Anvi Online Cloud Server for verification if you choose. Guard is probably the most important function as it provides real-time protection as users surf the net such as chatting online, making online transactions, downloading, etc. System Optimization is less concerned with protection and more with speeding-up yourPC. Finally, the Update Center allows you to automatically check for the latest malware threats and latest program versions in one-click.

Overall, Anvi Smart Defender works very well for a new anti-malware tool. It scans fast and seems very good at picking up malware. However, users have also reported that it's a bit over zealous too - identifying certain files or folders as malware which are perfectly safe.

At the time of writing, Anvi Smart Defender is still a work in progress although already gaining in popularity. However, it should be used with caution until a full release is made.
