You’re welcome.
If you check my signature you will see I use MBAM Pro (with resident protection enabled) and no problems with avast, just add the c_windows\temp_avast_ to the MBAM Ignore List tab.
I too would suggest the removal of S&D if you have MBAM Pro.
Since IE is an integral part of your OS you should keep it up to date.
With firefox, I would recommend that you have the following add-ons, NoScript and AdBlockPlus. I also have RequestPolicy, but you may find that too noisy (you would be surprised just how many external sites are accessed by some sites), it prevents cross site scripting (so does NoScript but it isn’t as flexible), which is commonly used in these driveby attacks.
