AVG Internet security issue after W'11 update

My laptop with Windows 11 installed got last update yesterday. After that my all browsers, starting with Edge, Firefox, AVG security browsers starting to block all webpages with security warning, red triangle in middle of page, does not allowing to continue. Using AI giving all information to analyze, the result is ended up in HTTPS security setting. Toggling it on-off sometimes helps, but if I reach my webpage I need to stay there to have access, otherwise I need periodically toggle checkbox on-off to reach my target page. The virus database is fresh, July 5, 2026, the Internet security software is from Jun 26, 2026. This issue happens only in Windows 11 after fresh update of OS
