Invalid certificates

[system]

Avast Web Shield is blocking access to certain websites because the certificate is invalid. I was able to access these websites a few days ago so what’s the problem now? Can anyone help?
P.S. I’m having the devil of a job reading the Captcha (?) letters!

What OS/SP ?
What exact version of avast ?

What OS/SP ?

I’m running Windows XP and using Firefox as my browser (does that answer the SP query?)
I have Internet Explorer but it won’t fire up for some reason.

I know XP’s old but, as I said, it has been fine up till a few days ago.

What exact version of avast ?

I don’t know, but my sub. was renewed in September and it says everything’s up to date so I assume I’m on the latest version.
