Wasn't sure where else to put this so I thought I'd ask here:
I was visiting a dodgy website to download a video from YouTube at 720p; malwarebytes browser guard warned me that it blocked something (a website or link something), and a different malwarebytes notification told me it stopped an outbound connection having something to do with firefox.
I also had qbitorrent running and malwarebytes has always hated my torrent applications (previously also complaining about Azureus/vuze), giving me tons of notifications about them.
Eventually though Avira warned me that it had stopped an intruder that had port scanned me and on multiple ports, something I didn't even know was a thing.
I've disabled the internet connection on my PC for now, is there any advice you guys have? I've never seen a warning like this from Avira before.
Port scanning by itself is not directly harmful. It just probes your computer's ports to see which ones are open and accessible and which services are running on said ports.
