Just encountered this exact proxy clearing issue on a Windows 10 (Build 1709) computer. Uninstalling Avast Free Edition eliminated the problem.

I am facing the same issue using Avast Premier (17.9.2322) on Windows 10, 64-bit (1709). As mentioned in previous posts the registry entries for proxy settings get deleted by avastsvc.exe. There doesn't seem to be a fixed period when this happens, nor a specific event that could trigger such strange behavior. Has anyone figured out the reasons? This is the only post I found that discusses the issue. It doesn't make any sense for many users that have to use a proxy for various reasons.

Same exact thing here. extremely annoying and fucking dangerous from a privacy perspective, especially for those such as myself who live in a country where you need a VPN to access the internet and viewing the wrong political opinion can get you a visit by police. Seriously F Avast for not looking into this. In the middle of browsing the system proxy resets with zero warning unmasking all your traffic and preventing access to western websites. Windows and Avast are both fully updated. Avast is reset, IE settings reset, network settings reset. I've reset everything and the issue persists. The only option I have is to uninstall Avast because this behavior is far more dangerous than the low risk of malware.

Hi, comrades - same way (process monitor, proxy settings reseting) i found this forum )))

Tests (not sure how it sound on english version of avast just)

1) Disabling browser-extension time2time recheck - not help
2) Disabling\removing all components (free ver) (except realtime, software updater. avast-itself protection disabled) - helps
(still testing)

Not good advice and certainly not resulting in good protection.
I've reported the complaint to Avast.

Hello,
I have been bothered by the proxy setting being deleted for almost 6 months now until I found this forum/thread. All this time I thought it was Windows Update that was causing the problem (as I found in the other forum).
Our company bought more than 10 licenses and we need the VPN and proxy setting in our work.
Work around for web browsing can be done via Firefox proxy setting but other Windows proxy setting dependent such as skype etc. has caused too much trouble.
Some of my team eventually uninstalled Avast from their computers leaving Windows Defender running instead... not a very secured environment I suppose.
I was able to capture and reproduce the problem via procmon in my Windows 10 environment which is having the same problem... proof that Avast has been deleting the Proxy setting.

I really hope Avast do something about this quickly. Otherwise, they will lose more users other than free version!
