I just figured out that those connections aren't just happening sometimes, they happen after every single PC boot. I didn't realize that at first because you have to open Resource Monitor immediately after booting to be able to see it, if you're even a second too slow, it doesn't show up on the list.
It has been connecting to a bunch of other sites too, always just sending a small amount of Bytes/s, never saw it receiving anything, and then disappears pretty fast. I'll list some of the sites below.
This is the only instance of AvastSvc.exe that connects to weird sites that make no sense to me, all other connections of any programs that I use always use the name of the program itself to connect to servers, never AvastSvc, so I don't understand the "proxy" explanation at all.
Is there a way to find out what exactly is starting this process at every PC startup?
Here are some of the sites it has been connecting to, aside from the ones I already mentioned:
