Another issue I've had since the update...

Hello Mike,
Based on the information you have provided, it appears that your computer might be infected with some kind of malware or spyware. It is not uncommon for malware to be bundled with free software downloads, which can then install unwanted pop-ups or browser redirects.
Here are a few things that you can try to resolve the issue:
1. Run a malware scan: It is recommended that you run a full system scan using a reliable anti-malware software, such as Malwarebytes or Windows Defender. This should help identify and remove any malware or spyware that might be causing the issue.
2. Check your browser extensions: Check your Chrome browser extensions and disable any that you don't recognize. You can also try disabling AdBlock to see if it might be causing the issue.
3. Reset your browser: If none of the above steps resolve the issue, try resetting your Chrome browser to its default settings. This will remove any unwanted extensions or toolbars and restore the browser to its original state.
4. Update Windows: Ensure that your Windows operating system is up-to-date with the latest security patches and updates.
If the issue persists even after following the above steps, it is recommended that you seek further assistance from a qualified technician or a support forum.
I hope this helps! Let me know if you have any further questions or concerns.
