Hi I have no idea how I was infected but for a few weeks like 10 times a day but randomly I open a website or click a link in Google Chrome and I get a 2nd tab called totaladperformance.com opening too and then a pop up in the bottom right of my screen and the voice saying a threat has been detected or identified.
Thing is a full system scan from Avast finds nothing. Malwarebytes Premium Threat scan finds nothing.
Avast obviously knows about it cause when the site opens Avast goes haywire but when the site isn't opening on its own Avast has no idea its on my system and I can't work out why.
Its not the websites. Same site nothing happens after reloading site and its happened on like 50 sites over the last few weeks.
https://www.radio-rentals.com.au/Think this site may be what gave it to me but am not sure. They are a legit long running aussie business which makes me unsure if its even possible they are to blame.
I was using a free Dreamspark student copy of windows 8.1 pro and then I installed Windows 8.1 basic retail edition over it so that when I upgraded to windows 10 i'd have my retail copy as the one 10 was an upgrade too. I now have windows 10 and had to uninstall Avast and reinstall since after the upgrade to 10 the firewall wouldn't turn on. Thing is this issue has persisted through from the pro install of 8.1 all the way to windows 10.
Right now I have a license for Avast Internet Security and it and Malwarebytes installed.
Thanks in advance for any help given.
