Adobe Update Popup in Safari

In iOS/iPadOS we have two primary mechanisms to mitigate potentially malicious websites...

1) The native Safari Browser may be augmented with an effective Content/Ad-Blocker component. There are many Blockers available within the App Store, of varying quality and capability, but by far the best is 1Blocker. This is sophisticated, highly configurable and receives regular updates to both binaries and blocking rules.

It should also be noted that with 1Blocker all processing is local - and does not rely upon an external third-party proxy of dubious trust. In addition to blocking unwanted content and malicious content, Safari becomes substantially more efficient; unwanted content is not filtered after download, but is simply not downloaded at all - leading to substantially improved rendering speed and reduced bandwidth utilisation. This has added benefit on metered connections (such as Cellular).

2) Malicious redirects and known malicious websites can be greatly mitigated by configuring use of a trustworthy Recursive DNS provider in preference to any automatic, or DHCP derived settings. One such provider is Quad9 - which provides effective protection against malicious websites. Other Recursive DNS providers exist - again of varying quality - such as OpenDNS and Cloudflare.

Here are the DNS Addresses for manual DNS setup on your devices. If you have the ability to do so, your Home Router should be similarly reconfigured to use the trusted Recursive DNS provider of your choice; this will largely automate optimised DNS configuration if you wish to rely upon DHCP for all connected devices.

Quad9 IPv6 DNS Servers

There are other alternatives to Quad9, such as OpenDNS and Cloudflare.

I hope you find this information to be helpful in resolving this issue.
