Hello.
I run a PC with 2 operating systems (dual boot), one is Windows 7, which is my main OS I use for pretty much anything, and the other is Windows 8.1 I use for misc. stuff (and for those Windows Store games :P)
Today I re-installed Windows 8.1 (I used to have Windows 10 instead of 8.1, but that's not important), and got nothing but Google Chrome, Discord, Malwarebytes (free with premium 14-day trial) and my graphics card's drivers on it. I went to the Chrome App Store and installed AdBlock, AdBlock Plus and Popup Blocker Pro. Now I keep getting messages from Malwarebytes that sites named "tradeadexchange.com" and "popcash.com" were blocked on Google Chrome. However, no site or even a popup, not even an ad ever opens at all, which makes it seem odd to me. Another odd thing is that I have everything I have on the Windows 8.1 partition on the windows 7 partition (and a ton of more things) too, and yet there are none of those notifications. I have tried a full scan, a full scan in Safe Mode, and have used Adwcleaner - nothing was found.
Is it a weird false alarm or truly a very stealthy adware infection?
