For the past month, Avast has been blocking threats in Chrome, usually with the same log description as the screenshot I've attached. I did a scan with Malwarebytes and it couldn't find any threats so I decided to start a free trial to activate real-time protection. Now Malwarebytes constantly gives me notifications that it has blocked redirects/pop-ups from www.tradeadexchange.com and popcash.net. I reinstalled Firefox and immediately upon opening it, Malwarebytes blocked the redirect so I don't believe this a Chrome issue. I have tried disabling Adblock/Ublock from Chrome but it has not made a difference.
Avast, AdwCleaner, Windows Defender, and Spybot have not found any real threats beyond browser cookies. I even purchased Hitman Pro but it too has not turned up anything concerning. I don't have any unknown programs or processes and according to Avast's logs, this issue began around August 4th, 2017. No significant changes were made to the system at this time and I did not install any unknown programs.
Today's Malwarebytes log shows two new domains blocked: www.liveadexchanger.com and www.1-1ads.com. the 8/31 log shows a threat from preview.ibb.co.
I also added the following to my hosts file but it hasn't made a difference:
Any help in getting rid of this annoying issue would be welcome. I'm tired of seeing threat notifications. I am currently scanning with Sophos Virus Removal Tool and will post the log here when it's finished.
