Proxy settings that won't go away...

One of the kids laptops is overrun with popups & redirects.
I have tried all the malware, spyware, virus, rootkit, etc., software I can think of & it won't go away.
Internet explorer will not work.
If I go to internet options>Connections>LAN settings, Proxy Server is checked. I can change to automatically detect settings, close, open back up & it's checked once again.
When trying to get on Internet, I get an error message that names the settings, 127.0.0.1:13828 & if I search the registry, I find about 5 instances of that.
Can I just delete all the keys that reference that?
Probably not the most conventional fix, but it seems that it would work...

There is a quite detailed article here on EE
http://www.experts-exchange.com/Software/Anti_Spyware/A_6650-Malware-Fighting-Best-Practices.html

To be honest the topic of this question will not attract a lot of attention as the issue is much bigger than proxy settings .. and disinfecting a badly malware/adware/spyware infected PC can be a time-consuming job.

Provide a lot more detail on your Windows system, all the tools you've used and others may contribute to your next steps.

Have you tried the FREE version of MalwareBytes which is an excellent tool for removing malware/spyware
https://www.malwarebytes.org

If you search here on EE you'll find LOTS of people with similar experiences as these pop-ups and malware/spyware are rife on the Internet .. and PCs need to be properly backed-up, protected and updated.

I guarantee that removing a few specific registry entries will not be enough as a lot of these programs re-create registry keys on restarting or rebooting anyway.

Proper cleaning and removal of the malware is really the only solution.

For serious infestations it can be faster to wipe and re-install windows .. however if there is important data, music, games, photos it might be worth taking the time to try and clean it down.

Yes, time consuming in deed.
Not a whole lot of critical stuff on the laptop, so I just wiped & reinstalled & said 'let that be a lesson...'
