First of all, sorry for my bad english.
A while ago, Adwcleaner detected a registry error related to a Proxy server, I delete it, I cleaned the registry with CCleaner, did a full scan with MalwareBytes, SuperAntiSpyware and Microsoft Security Essentials and they detected some viruses, but nothing related to the Proxy.
I tried everything I could to fix it, but it was impossible, it reapeared everytimes I turned on the PC, however, some guys who knew about informatic told me that it was probably a false positive, so I forgot about it.
A pair of days ago, I entered AZLyrics (dumb choice from my part) and beause those types of sites have bad reputation, I asked on Reddit if that place was dangerous, luckily it seems that only the adds contained malware, and AdBlock Plus blocked it.
However, I runned all those scans I mentioned before (except the full Microsoft Security Essentials scan, because 6 hours of scan is too much) and I used RKill this time too, but, none of them detected nothing (except AdwCleaner and the Proxy thing).
So, I decided to try RogueKiller, because TroneScript uses it in it's scans, and it detected the proxy problem from AdwCleaner but much bigger.
Obviously, I runned every scan again (complete Microsoft Security Essentials scan included), and none of them detected anything again (except AdwCleaner), so I clean the registry with RogueKiller, and it seems to work, however it doesn't detect the "PorxyOverride <-loopback>" thing, but I decide to ignore it.
Everything seems fixed, but the next day, all of that appears again, with a svchost.exe process included, I clean all of that, cleaned the registry again with AdwCleaner and checked every svchost process with the task administrator (every of them was from System32 folder)
I don't know what else to do, I'm in danger or it's just a false positive?
I have some reports, but I'll leave the one which detected all the problems at once:

If you need some more information or I forgot to explain something, tell me and I'll reply the fastest I can.
Edit: also, I know I'm running an 32 bit version of RogueKiller, but is because I use a 32 bit version of the OS and I don't have the installation disk for Windows 7 (I borrowed it from a guy I know).
Thanks.
