Polar Anti-Malware FREE (Updates)

I just installed it. Looks good with the API lookups.
Just found a bug on the update time. Says last update is 2026-1-8.
I'm glad that you are a fan of Polar. There is no issue with the virus database update date specifically for the Polar engine.

Updating the database requires effort, but it will improve over time.

Kaspersky does not scan the entire file; instead, it reads the file's hash or the IP address integrated with the firewall and sends it to opentip.kaspersky.com. The query is returned either as infected or clean, and files are not uploaded to opentip.kaspersky.com.
VirusTotal does not scan the entire file on the computer; instead, it only reads the hashes of executable files and sends them to www.virustotal.com. Queries are returned either as infected or clean, and only unknown executable files are uploaded for analysis to VirusTotal.

The project is getting more and more interesting.
I'll see if I can set aside a video for it ;)
 
I'm playing around with it a bit. VirusTotal runs first, followed by Kaspersky (I've tweaked the settings a little).
It works pretty well together. It deserves its own video.

I'm forcing Kaspersky by disabling VT... It's still responding, BUT

Hi @tiktoshi

Will you add the expire dates of the Kaspersky token and for the virustotal api key for display that

The Kaspersky key is valid for one year. You can access the Kaspersky website and verify.
Total Virus has no history; it has a maximum limit of 500 files.
Total Virus in Polar scans a file for the first time, then saves it in a hash database file. If the file is in the database, it does not connect to Total Virus.

Hello,

I have a question regarding the VirusTotal caching mechanism.

From what I understand, when a file is scanned for the first time, Polar queries VirusTotal, stores the result locally based on the file hash, and then does not query VirusTotal again for that same hash.

If this is correct, what happens in the following scenario?

* Day 1: a new malware sample appears and VirusTotal reports 0/70 detections. Polar stores this verdict locally.
* Day 2 or Day 7: the same hash is now detected by multiple vendors (for example 25/70 or higher on VirusTotal).

Will Polar automatically re-check VirusTotal after a certain period of time (TTL), or refresh the reputation cache periodically?

If not, wouldn't this create a situation where an initially unknown 0-day sample could remain trusted indefinitely on systems that have already cached the original "clean" verdict, even though VirusTotal later identifies it as malicious?
