Trouble logging onto the CC website.

After changing from Norton anti-virus to McAfee anti virus software, I found that I could no longer logon to the Caravan Club website. I could enter the website main pages, but Internet Exporer ver 8 would not allow me to use my logon to access the member only activities. 
I spoke to the website team who advised me try another internet browser. I downloaded Google Chrome and hey presto! Logon was acheived without difficulty, with a faster access than before through the pages. 
Thanks to the web support team.
