Scam virus warning advert leading to avanquest “Onesafe” affiliate software.

Never a dull day… A call from a client today who had been visiting a local council website in the UK. Not sure why but this council website has adverts on it.

One of the adverts on the page for a short period of time was hijacking visitors to a fake virus warning page. Unusually this one isn’t coaxing people into calling a fake technical support service. This time it, after a lot of loud noises and fake screens, tries to get the victim to download some system cleaner software.
The first URL involved in this is a click tracker or forwarder that seems to only allow a single visit and then won’t allow you to visit it again:

Which then forwards the victim onto an AWS Cloudfront site:

    Did you manage to figure out what is causing this? I’ve been experiencing this issue as well, I’ll be playing a game in full screen and then this URL will open by itself. I can’t work out what’s causing this! Nothing found when I did an Avira scan

  2. An advert on a website that was left open on the computer.

    Hmmm, I have AdGuard Adblocker installed and when this last occurred for me I only had Steam and Wikipedia open! Was “hoping” it was a virus that caused this. Unfortunately it seems that this is a recent issue, as this is the only article I’ve been able to find.
