Please help me!

Fresh install of Avast Internet Security 2018 on slow computer(but very good) having Vista Home Premium SP2 installed.
Internet Explorer 9.0 fresh install.
All sites with protocol HTTP accessed very well.
Some sites with HTTPS give error certificate.
Some sites with HTTPS are completely blocked.
Some important sites(ex. Wikipedia) work. These are exceptions.

Cannot install Google Chrome… Many problems. I think it’s time to unistall AVAST on my Vista Laptop and to try another antivirus COMPATIBLE.

PS: Google Chrome doesn’t support Vista anymore.

What happens when an older operating system reaches end of life, you need browsers that can run on it and support TLS 1.3: https://duckduckgo.com/?q=tls+1.3&t=ffab&ia=web

Thanks to all !

Finally i installed Avast Free Antivirus.
Now i have installed Firefox 52 compatible Vista. I made configuration for TLS 1.3.
My old computer started a new life. Sleep, hibernate works. No errors in browser for SSL certificates.

I will try next weeks to install a new version of OS (WIndows 7 probably).
Until that i will try to find all drivers compatible for my old system. I will try to upgrade memory.
I think that is enough.

Broblems? NO BROBLEMS. Avast really knows what is that…

PS. For me it is really a pleasure to comment in this forum.
