Tor browser

Hello,
There is a bit of discussion about:
- https://community.f-secure.com/en/discussion/129274/tor-browser-has-been-blocked
And similar topic for Mullvad Browser:
- https://community.f-secure.com/en/discussion/129219/mullvad-browser-blocked-by-v25-2
The discussions contain both possible reasons for detection and explanations of whether the file is safe/harmful or not. In addition, possible solutions (options) to the situation are offered.
In general, if you downloaded Tor Browser from official source with further integrity checks, then it should be safe one. The detection (Drop.Win64.MemMapSelf.204) itself is likely false positive and just a generic reaction to certain component or its way to be used.
If so, you can try adding the entire Tor Browser folder to exceptions before first browser launch (Described here: https://help.f-secure.com/product.html#home/total-windows/latest/en/allow_program_on_sys_control_blocklist_to_run-latest-en)
Or send the file (if you can find which file was deleted or quarantined) to F-Secure Labs for analysis. The place is there: https://www.f-secure.com/en/support/submit-a-sample
However, can you share a bit information about your situation:
When I'm using Tor I'm getting the message that this file below is blocked. Then I can't access Tor unless I re-install but sme problem occus again.
Doesn't this happen immediately after launch? But only during use, for example, for some days or minutes or hours without this 'blocking' event?
Is it tied to a specific action then? Checking for browser updates or navigating somewhere?
Thanks!
