Since a few days ago, several different pieces of software have completely stopped being able to connect to the internet: Whatsapp for desktop, Discord for desktop, Teams for desktop, Microsoft Edge and Google Chrome. Everything else still works normally, to the point I can access Whatsapp, Discord and Teams through the Firefox browser. I couldn't get any specific error message other than ERR_CONNECTION_RESET.
At first, I tried disabling both Kaspersky's and Windows' firewalls, and even disabling Kaspersky's antivirus didn't work either. Weirdly, today, I have tried again disabling Kaspersky and said pieces of software magically resumed being able to connect to the internet. Before that, I had tried several troubleshooting steps, without any success: (1) restarting the software; (2) clearing the browsers' caches; (3) installing the latest versions; (4) rebooting the computer; (5) restarting the internet connection; (6) connecting through wifi (I usually do so through cable); (7) resetting network settings as an administrator with Netsh winsock reset, Netsh int ip reset, Ipconfig /release, ipconfig /renew and Ipconfig /flushdns; (8) uninstalling all VPN software (I don't use VPN, but I'd read that some pieces of VPN software can still silently interfere with the internet connection).
The several steps I took, coupled with the fact disabling Kaspersky now enables said pieces of software internet access, point to Kasperky Total Security as the culprit.
I wouldn't be bothering you if this were a simple "add the blocked software to the trusted list", because all applications I mentioned are already in Kaspersky's trusted list, as shown in the attachments 1 to 5 (Tools => Manage applications => Application control). However, they can only work if I add them to another exclusion list, called "Exclusions", which be accessed by [Cog icon]=> Threats and exclusions => Manage exclusions (see attachments 6.1 and 6.2). I cannot overstate how weird this is: even though the pieces of software I mentioned are already in Kaspersky's own "trusted list", Kaspersky has started to suddenly and silently block them until I manually add them to another of Kaspersky's lists.
I'm asking for help because as a layman, I'm afraid that adding the blocked pieces of softwares to that specific "Exclusions" list creates a security risk, and, to be honest, the need to manually add softwares alreadly listed as trusted to another list looks a lot like a bug. I'd like to definitely and safely address this bug or, at the very least, know how can I safely restart using Chrome, Teams, Discord, etc.
My Kaspersky is in Portuguese, but I'm asking here in the English forum in order to broaden the support I can get.
Kindest regards,
Michel
