Local proxy system for filtering out advertisements and malicious web code

careful of infected downloads of this that install without permission and carry privoxy plus malicious software.
Privoxy spams down your browser with adds. It slows down your PC as it uses more than 50% CPU power. Hard to uninstall as it install it self again even after being removed in safe mode. It's a piece of crap virus, and all other ratings are written by the authors!!!
Prevents browsers from connecting to the internet. Works with other viruses to prevent fixes from being searched
privoxy.exe is an application that always trys to brind up ads and also is listed as malaware on most computer
  Nunya Bysness  
It gives you ads EVERYWHERE
well I did not install this process so why should I trust it its open source anybody could alter it and pack it with something else or download it when I visit there site without my permission there fore in my opinion don't trust it!!! if you never installed yourself
Annoying piece of shit will completely slow down your PC. Remove it by any necessary means as soon as possible!
This thing is messed up. Replaced Google Chrome with it's own version, creates a proxy that redirects traffic back to localhost @ 8118 and injects so many ads and insanely intrusive system popups telling you your system is infected and you have to pay to clean it. Insanely hard to get rid of. Constantly reinstalls itself and even runs in safemode.
Installed without permission. Continuously causes internet problems by setting up a proxy which is completely unnecessary for me. If I wanted a proxy I'd get something legitimate. Also program files folder has a really unprofessional name: Gamma task mEnager. What does that even have to do with setting up a proxy. Too many things off with this background process so it's definitely not doing your computer good. I guess it's spyware since all your internet has to go through the program...

Reinstalling annoyance. Probably a virus based on collected evidence.
I occasionally go into programs to see what has been installed. That is when I noticed the AFC Secure Net Folder in my program files (x86)folder. By that time 12 hrs later I was shut down. Couldn't get online couldn't run virus program, restore nothing! Had to do restore a backup image made by Acronis true image.
Malware... It prevents connecting to the internet.
Spams your computer/browser.
VIRUS. Bogs CPU with ads and doesn't turn up on antivirus or anti-spyware scans. Hard to remove, do not install!

privoxy installs a proxy server and it will log everything you do and it's hard to remove, this is a piece of crap. don't install!!
Privoxy is used by spyware processes
Ok there is obviously a problem with some malware using the name privoxy.exe. I would just like to say the real privoxy from is a genuine web proxy used for filtering ads. It's just sad its name has been hijacked.

This is malicious adware that uses a proxy to spam the user with adverts. To stop it in Windows 10, go to your network settings, click 'Proxy', and make sure where it says 'Use proxy' it says 'off.' This will disable the proxy.
Not to be trusted. Remove all AFC secure net stuff, kill the service remove chrome and reinstall. Even then it comes back.
Use AdwCleaner to remove it. It keeps coming back, but it's a temporary solution for now at least. Still working on nuking this thing
  Fionn C  
Annoying virus, set's up proxy to direct you to advertisement sites, maybe even more dangerous. Remove ASAP
definitely some illicit activity, I didn't even install it and here it is setting bogus proxy settings (aka sloppy data leak)
  fuck privoxy  
adwear. Giving you publicity everywhere, with a whole bunch of liks to fake anti-virus. When you deleat, it changes your proxy setting so that you canont log on to internet after deleting it.
Privoxy itself is benign and, when used correctly, can be used to improve your computers security. However, it appears that some malware uses or pretends to be privoxy. If you, or your IT department, installed privoxy from, it is not an issue as long as you know what you are doing. Other software and settings may require it in order to work and may install it as part of setup. If you did not install it yourself and aren't aware of any software that may be using it, its probably a good idea to run a malware scan.

It creates a folder on Program Files (86) named AFC Secure Net and it has 7 files or more inside this folder including Privoxy.exe. As soon as I see the adds I go to Task Manager stop the Task of Privoxy.exe file and go to Program Files(86) and Delete the AFC Secure Net folder. After I start the browser Go to Proxy Settings and turn off some Local things that Privoxy does it by default.
Privoxy is opensource and can be rewritten by anyone to be other than it was meant to be. Currently I'm running it as an adblocker on Linux. It seems to be extremely good at that. Can also be used as parental control to block pretty much anything

It makes ads in your web browser (very annoying and without your permission) and put localhost:8118 as Proxy in your internet settings. It keeps coming back if you delete it normally but thanks to ESET antivirus it's gone.

Best practices for resolving privoxy issues

A clean and tidy computer is the key requirement for avoiding problems with privoxy. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
