Can't remove or fix Privoxy


Recommended Posts

Hello all, I've been using Avira as my daily for some time now, and Malwarebytes occasionally when I feel something is off in my system, or like just recently, when I started getting pop up ads on certain websites. After running the scan it alerted me to the potentially harmful Privoxy residing in my system. I told it to remove it, it told me that all items were successfully removed, and it just needed to restart, but afterward I was still getting the pop ups. I did another scan and Privoxy showed up again, so I removed it, and restarted, and it was still there afterward again..

Now, from the bit of research I did, it seems that Privoxy isn't in itself a harmful program, it's simply a proxy, though it can be used maliciously. How can I fix it so that I stop seeing these ads?

And just for some insight, I use the latest Firefox and uBlock Origin.

Thanks!

Sorry for taking so long to respond, chkdsk told me there were 4Kb in bad sectors, so I ran chkdsk /f /r to try and fix this, and it actually corrupted my filesystem.. I spent the past couple days trying to fix it, and finally on a whim I tried automatic startup repair which did it. Obviously I was very relieved to have all my files and work back..

I tried everything you said and was optimistic at first, it seemed my problem was gone. However, after a few hours, the pop-ups returned.. I'll include all my logs below. Kasperky found two non malware objects that were potentially a threat so I told it to quarantine. I'll post a pic because I cant get the log file. Also, why is it important to run these things from desktop?

 

Thanks again!

Did you run AdwCleaner, can I see that log. Also which browser is affected by popups, one specific browser or more than one browser...

 

 

Yes sorry, I'll attach it. It affects all my browsers, Firefox, Chrome, Edge.

Also, FRST quarantined legit programs like EVGA Precision X and OC Scanner, and deleted all my pinned folders in File Explorer.

Though, if it's affecting all my browsers, wouldn't it be a system issue and not within the browser itself? I can see Privoxy and pS2PClnt running in my processes.

Apologies but I listed Privoxy entries for removal with the first FRST fix, if they are back run frst again as follows:

Run FRST one more time, ensure all boxes are checkmarked under "Whitelist" but only Addition.txt under "Optional scan" Select scan, when done post the new logs. "FRST.txt" and "Addition.txt"

Currently, whenever I try to run FRST, it start up, updates and says it's ready to use, and then endlessly loops restarting and updating, and I have to kill it through task manager.

Which programs were removed by Zoek, yes FRST is just a scan to have another look at your system, no changes are made..

 

Discord Appdata, 7 Days to Die Appdata, EVGA OC Scanner. Could the reason we are having so much trouble removing it be that anti-virus sees the inserter as a harmless program?

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into.
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.

Ok keep me updated...

 

It may not be related, though, around the time of doing the fix, my computer started freezing randomly and the desktop background will turn black at random points as well. I thought maybe it was the graphics driver so I did a clean install of my Nvidia, but that didn't help. I included the fixlog from FRST just in-case it removed something it shouldn't have that you notice.

 

On the Privoxy side of things, it has yet to return, and my webpages are no longer plagued by the pop-ups, so I'm very hopeful and thankful for that.
