I've been noticing my computer is very slow and uncooperative, often needing multiple access attempts or to be refreshed in order to download or display. I thought nothing of it... until I tried to check my email. And my facebook. And my one of my favourite forums.
I keep receiving the same error message on a few sites, about the security certificate being expired and content being blocked.
I Googled and found an article which said it could be related to 1. time and date on my computer 2. the certificate could be genuinely expired, or 3. it could be malware.
I don't think all of the security certificates were expired, because it's a few sites. So I ran a full system scan using Avast! and found no threat. I changed the date and time as recommended - but then I received another error message when I clicked 'update' to synchronise with the internet time server.

Also I keep getting an error message when I try to get Windows updates. Pic http://www.facebook.com/photo.php?pid=251385&l=4a0acaa576&id=100001338721987
I confess, I have bypassed them because I really needed to access my emails. Don't kill me
Is there a way for me to find out what's causing all this and fix it?
