Quttera states it is clean: https://quttera.com/detailed_report/twittervideodownloader.com .
BTW - web site verification can also be done at Virus Total, Sucuri, and like web site scanners. You should verify with those first prior to posting.

Yes, ESET products for Windows detect also Mac malware.

Yes, It can scan dmg files. I don't have one with any malicious files embedded to test the detection aspect but I assume it would.
 

That is the hash value for same file in my Win 10 x(64) 20H1 build.

You can upload your version to virustotal for more checking by AV engines to be more sure
It seems that this WaasMedic is related to Windows Update.

Have no clue what could have caused WaasMedic_Agent.exe to appear on your desktop.
However, there have been recent postings in regards to Eset firewall not working properly in Interactive mode. I assume you were in Interactive  mode when the Eset firewall alert appeared?
I would just delete the desktop entry and post back if this activity occurs for another process you create an Eset firewall rule while in Interactive mode.

Did you exclude Eset files from ShadowDefender? Looks like that might be the issue: https://www.wilderssecurity.com/threads/nod32-shadow-defender-how-set-exclusion-list.322742/

Do I understand it correctly that if Shadow Defender's Shadow Mode is not active it does work correctly?
From the description of Shadow Mode it looks like it may prevent some things to be done correctly.
 

Looks like no diagnostic logs were created

Therefore I assume that you skipped the initial steps:
- enable advanced logging under Help and support -> Details for tech support
- reboot the machine
- disable logging

Open Eset GUI -> Setup -> Advanced Setup.
Select User Interface -> Statuses -> Application statuses -> Edit.  Mouse click on "+" for Network Protection. Are all statuses in that section enabled per below screen shot?

 

Just wondering if in advanced you have some notifications disabled 

Please carry on as follows:
- enable advanced logging under Help and support -> Details for tech support
- reboot the machine
- disable logging
- collect logs with ESET Log Collector and post the generated archive here.

Looks like you have firewall in interactive mode. If you delete the permissive rule, you'll be asked for an action should the application at the given path be run again which is unlikely to happen.

Thanks for that itman , I was trying to remember the name of O&O software , I completely forgot about it and Cortana drove me crazy recently , trying to disable it every way I can , but Cortana is mighty keeps resurrecting itself haha
Thanks!

Unfortunately without seeing all parameters of particular rules it's not possible to tell if they are identical or not. Please provide logs collected with ESET Log Collector.

First, monitoring Win 10 individual services via Eset firewall is somewhat an effort in futility. Eset attempted that a while back in a prior release and quickly abandoned it. Hence, why all Eset default firewall rules for svchost.exe are not service specific. Why? Because there are many hidden services used by Windows that are not specifically listed or controllable via Control Panel -> Admin Tools -> Services.
In regards to DoSvc, it is Win 10's Delivery Optimization service used to speed up downloading of Win Updates primarily but also used for other Microsoft apps. If Win 10 is not restricted in some form on how updating is performed, you can end up with what is described here: https://social.technet.microsoft.com/Forums/windows/en-US/b94d8e74-58de-451a-b137-7ec2028adc27/delivery-optimization-service-downloading-something-and-using-all-my-bandwidth . Win 10 introduced runtimebroker.exe via BITS processing that allows one service to spawn multiple instances of another service/process. This is in effect what your Eset firewall rule set shows in regards to DoSvc service. Also what service is actually started in regards to DoSvc is C:\WINDOWS\System32\svchost.exe -k NetworkService -p.
My advice - quit globally monitoring individual service outbound network traffic via Eset firewall.

Correct. The rules are not duplicate since the path to the application is different.

I belive you can delete them but don't think leaving them will cause any issues such as space etc. As you can see from the folder path each location has a slightly different version name.
The problem with Windows Store apps is their folder location and I believe exe. name changes with each version number. For example is the folder name was app 1.0 the new folder might be app 1.5 and so on. As the location and so on change eset treats it like a new app and a new rule gets made. 

Unfortunately we have not seen that message yet. If you are experiencing issues, such as with viewing websites, please open a ticket with your local ESET support for further investigation.

The product in question is correctly classified as PUA since they don't adhere to good practices.

It's not you...we are transitioning our product release communications currently for all products but once the process is finalized, we'll resume posting. 

The security report referenced is the aggregate event status one that shows ever 30 days.
When you have questions about Eset settings, always click on the "?" on the GUI page. This will open Eset on-line product help which will show detailed explanations for the settings: https://help.eset.com/eis/12/en-US/idh_config_ui_notifications.html

The best way to look at pua also is there are many programs that people use that could be risky e.g. there are many people using registry cleaners and similar stuff. They are often risky and its debatable if they should be used, sometimes they may also try to install unwanted extra stuff, nag you to upgrade and other suspicious stuff but people use them and they like them. 
I often see people asking why their favourite software gets classed as a pup and its usually for something like that. With pups its not a virus so its down to the user to decide if the risks are acceptable
