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...
