win10 or win11

[hermesa]

So the story is long here.I got 2 houses in 1 town , house 1 have 200mbit router download speed and house 2 have 300mbit router download speed.I switched them because I no longer live at house 2 and I switched them at least to use the 300mb speed of the router from house 2 to house1 and I had to reset my security settings on both of them in order to work(i think its something related to my internet provider).Everything worked fine for 2-3 hours when my internet suddenly stopped.I noticed that only my ethernet stopped on my desktop pc while wifi was still working on both my laptop and tv and phone.I tried to turn on wifi on my desktop pc but it wasn't working.I opened proxy settings and I saw something changed my proxy settings to some IP adress that I didn't recognised and that stopped me from using ethernet until I unmarked that settings which was located in Control panel>>proxy settings>LAN settings>Proxy server.After some research I read somewhere that It may be malware that changed my proxy settings so it can track my passwords or something(I guess I understood right ,I don't know) And now I am little suspicious that my PC is infected with malware.I ran some windows deffender scans as well as malwarebyte scans too and offline windows defender scan but still I don't think I am free of malware and just to be sure it is not that my last resort is reinstalling windows. Win10 works fine for me and it's end is around october 2025, but I thought that win11 will last longer than win10 so I can go with win11 before I have to reinstall 1.5tb of game files again on the new win12 when it gets released whenever this happens in the soon future but it turned out they both end around the same time, should I go for win11 or win10 when it comes to gaming and security ?
The malware is whole my fault It didn't came from nowhere but the copy of windows wasn't original too but pirate activated.

Sorry for my english,it's not my native
