Help with saving cookies

I had a virus which this group successfully helped me erradicate. Obviously with the cleaning out process and tyding up my cookies were probably wiped. Now when I log on say this forum or hotmail and I check save password and user name then next time I visit it hasnt saved and have to go through the log on each time. I normally wander around several sites during a 4 hour period and then log off each evening but having to log on each visit I could do without. It worked ok before the clean up and saved the cookies. Anyway I can bring this back? thanks scudo

I have edited this as it still does not appear to work and I have to re enter passwords etc everytime I log on,
This only started after my pc clean up, link below.
