Hi there, my first time posting on your forums here, but I've been a fan of Malwarebytes for as long as I can remember.  Great tool, it's helped me so much over the years. (and so far I really like what I see in regards to the Premium, I will most likely purchase it, especially now with this problem...)

 

So here it is.  On my previous windows installation (Windows 7) I got some really nasty malware that was loading ads from a bunch of different places, but most notably "adnetworkperformance.com".  I downloaded Malwarebytes Premium, to see if it could fix the problem, but no dice.  I tried running Malwarebytes Anti-rootkit and junkware tools, as well as Nod32, Spybot, Hitman Pro, and clean installing my browser. (I use Firefox and Chrome both, and both are affected by this malware)

 

So I decided to finally upgrade (a fresh install, I did not actually click "upgrade") to Windows 10... as I was at my wits end and nothing worked.  So here I am, a formatted hard drive - I install Malwarebytes Anti-Malware Premium, and shortly after installing Java (from Java.com / Oracle).  Same with adobe flash player.  There is zero chance that I clicked a fake on either of these, yet somehow one of the first things Malwarebytes starts blocking is adnetworkperformance.com!   Maybe I'm mistaken, but this shouldn't be possible... this was not an upgrade, the hard drive was completely wiped... so my question -

 

Would Malwarebytes be blocking adnetworkperformance.com on multiple websites if it my hard drive WAS NOT infected by malware?  I'm not visiting fishy websites - the fishiest ones by far are facebook and cnet, which I've used for as long as the internet was a thing for me.  It's fairly frequent when visiting a webpage that adnetworkperformance is blocked, and it depends on the web page... I never see the ads, at least not yet, because they're being blocked by malwarebytes / my browser, but infections from things like this tend to get worse. 

 

I'm at my wits end... can anyone possibly clarify whether or not there's a chance that I'm actually not infected by malware on a clean install?  Where can I even start with a problem like this?  I've searched google and tried every single solution I found except for manually modifying my registry.   I considered myself to be pretty adept at using computers, until now...  I have never had a virus / malware like this - how can it still be affecting me after a format?  Any suggestions would be immensely valuable to me...

Apologies, I can't figure out how to edit my post.  I believe I put this in the wrong forum, I thought I was under the general Malwarebytes Anti-Malware help forum.  Can somebody please move this to the appropriate forum?  sorry about that...

I'm just posting an update as I believe the problem has been solved.  A user mentioned to me that my browsers could be syncing and automatically installing old extensions and such.  

 

I decided to uninstall all extensions in the 3 big browsers, and then followed their instructions to "reset" or "refresh" the browsers (which returns everything to the basic default).  Afterwards I deleted all partitions on this drive (to be safe, as I failed to delete the system reserved partition the first time anyway), and reinstalled Windows.

 

So far this infection has not come back and I have not seen Malwarebytes or Nod32 block any websites... so maybe it's taken care of?  I feel like the Java Developers Kit that was installed (it was from the Oracle java website) has something to do with what was happening.  As I understand it, the JDK has been used to exploit people's systems for a long time now, so maybe I shouldn't be surprised.  In fact of the very few extensions I had installed, that was the only one that seems likely.   

 

This is by far the most persistent adware I've encountered, with the biggest impact to my systems performance.  I have a more or less top-of-the-line PC that I built, that adware can affect it's performance that much is ridiculous, but I wouldn't want to do anything on an infected PC even if it didn't. 

 

Thank you for the suggestion that lead me in the right direction!   I've been playing computer doctor for days and getting pretty tired of it, so... thanks a lot!  Now I can go back to loving computers again.

Hi. I am so perplexed by Facebook blocking my signon stating I am infected. According to my report (Premium MWB) I am clean and another run from Essentials states clean. Nothing found. I reset Chrome and cleared everything from history several times.  And  am not familiar with this company insisting on download and thought to share, for awareness.  https://www.trendmicro.com/en_us/contact.html

I'm not sure if you meant to post this inside this thread - but you'll get much better help of you post your own topic.  My problem was very unlikely to have been caused by facebook and didn't really have anything to do with it either.  

I'm far from an expert, but have you verified that the website is the official facebook website?  If it is - you should try cleaning your browser cache - cookies, temporary internet files, etc.  It depends on your browser, but typically those options can be found in "settings" under your browser interface.  Some may call it "options".  That's about all I can think of, for your issue, but you'll get much better help from actual troubleshooters here on MWB.
