I got one of those take-over screens, such as in forced false impressions, but afaik, it did not come from an app as I tried nearly every anti-malware, and none found anything.
Previously, a website covering NXIVM was taking a really long time to load, and I felt suspicious. So, based on this, I looked up chrome vulnerabilities, and learned to clear its cache. This (apparently) solved this problem.
Keep in mind that the problem was outside of chrome where malware was disguising itself as the app I had just previously used, as if it was an extension of that app. Also, it seemed to choose non-google apps.
Knowing the 'whiley cracker' for 30 yrs now, I don't know if it chrome cache was infected as the code may want users to think that while waiting for some other opportunity that we can only imagine.
What is concerning is that it appeared to run an app from the chrome cache as an independent app. Is this possible?
I should add that it is a Sky Devices phone, where new products are being introduced without warranty support for its broken phones. They have chrome configured to load their site, and the 'false impression' screens coincide with their product page updates.
