Done. Thank you very much.

Sorry, the fixlog. Fixlog.txt

Well well, that yellow message disappeared and the "use server proxy" was unchecked. Awesome Thanks. Any explanations of what happened, in order to not repeat the same mistake again. (I saw that the history of Firefox and a part of Chrome was deleted). (Ccleaner tells that there is a missing shared DLL with C:\Windows\system32\router.exe, should I fix it?).

Ok, here they are Addition.txt FRST.txt

Well, I restarted my PC, and I went directly to the proxy settings, and the proxy server wasn't checked! But unfortunately, it went back after few seconds. Please note that when I opened the proxy settings window, the internet connection wasn't established yet.

Yeah, that's what I do every time I start my PC. It only goes back if I shut down/restart my PC.

I restarted the PC, the proxy settings went back to proxy again. Fixlog.txt

Ok, here is the files. Fixlog.txt search.txt

The attached file is fixlog.txt not fixlist.txt. I don't understand what is: "Attach search.txt"

No, still the same.

Done. Fixlog.txt

I ran the Malwarebytes Anti-Rootkit but nothing was found. Addition.txt FRST.txt mbar-log-2015-01-05 (19-13-04).txt system-log.txt

Hi, Everytime I restart my PC, the proxy settings gets back to "use a server proxy" and in "advanced" the address is 127.0.0.1, port 8080 and in exceptions I see this: "<-loopback>". Under network parameters, there is in yellow a message who says: some parameters are controlled/managed by your system administrator. Few days ago, Kaspersky found a trojan called something like proxy changer, but it has been deleted, although the problem persists. I tried many solutions but nothing solved the problem. So, any help would be appreciated. Addition.txt FRST.txt
