Everything seem'd to be calm in the past week - until the same IPs poping up again, and as usual Malwarebytes doing a good job blocking these IPs. its starting to get annoying now.
I see this one particular IP which isn't the first time trying to connect to my system, so I've done a small research about this IP, and it seems that Malwarebytes Labs has this IP on their database. (Pictures below)
First it tried to connect via svchost.exe, second via Nvidia programs, and third which is unknown (assuming it tried to connect via svchost again)...and with different ports.
I updated my router framework, changed the router passwords, and checked and tweaked all the security settings. I also scan my PC regularly via Scan Schedule, and even full scanned the whole C:/ drive. no threats detected.
