I've been giving it a try. When installing it, the license agreement is only shown in Turkish. However you can copy the license agreement text. So you would be able to paste it into Google Translate if you felt the need to read it. Apart from the license agreement, everything else is in English.
The user interface actually looks really nice, and is entirely in English. However, as you will see from the screenshots, the configuration options are extremly limited. Any threats detected by the realtime protection or on demand scans are auto quarantined, and there is no way to change this behaviour. There is no proactive protection.
I ran a scan on a malware pack from early in the month (with just 6 samples), and nothing was detected. Next, I scanned over 6 gigs of installers on a flash drive (this laptop only has USB 2.0), which includes many PUPs. The scan took just over 5 minutes to complete. Eighteen files were detected and automatically quarantined. Nine of these files were detected as UnclassifedMalware. One of these is a definite false positive, while the others could be considered PUPs. It would be better if they were actually detected as PUPs, but sadly it is very common for harmless PUPs to be detected by antiviruses as malware. Also, there was one more false positive.
Subsequent scans of the same folder, were completed in just two seconds.
When restoring files from quarantine, there is an exception option, which I thought would whitelist files when restoring them. However, it restores files without whitelisting them, and they are detected again when you do a subsequent scan. There is no option to manually exclude files or folders.
