Always state your full Windows version (e.g., WinXP SP3; WinXP 64-bit SP2; Vista SP1; Vista 64-bit SP2; Win7; Win7 SP1; Win7 64-bit; Win7 64-bit SP1) when posting in a forum. Please do so in your next reply.

Please answer all of the following diagnostic questions by number in your very next reply (no need to quote this post):

1. What anti-virus application or security suite is installed and is your subscription current?  What anti-spyware applications (other than Defender)?  What third-party firewall (if any)?

2. Has a(nother) Norton application or a McAfee application EVER been installed on this computer?

3. Did a Norton free-trial or a McAfee free-trial [pick one] come preinstalled on the computer when you bought it? (Doesn't matter if you never used or Activated it.)

4. Are ALL of the following updates listed in View installed updates (not Update History)?

I have NOT got KB2497640 ( I have IE9); KB976932 as my PC was new in March; KB2524375 or KB2393802 - I assume the older ones were put on by Dell prior to shipping

I'd very much doubt it, RR!

1a. If you installed IE9 prior to (before) 12 April, KB2482017 should be listed in View installed updates.

1b. If you installed IE9 after 12 April, KB2497640 should be listed in View installed updates.

[Note: KB2497640 will not be offered via Windows Update nor would you be able to install it manually as long as IE9 is install.]

2. Even if SP1 was installed (and you've told us that this is NOT the case), both KB2524375 (released 25 Mar-11) and KB2393802 (14 Feb-11) should be installed.

I have got SP1 - I must have downloaded it when my PC arrived.   I have KB2524375 and KB 2393802.

The only thing that is not there is KB2482017.  I downloaded IE9 on 6 April.

All updates went fine today - I never have had any trouble before it is only the few Windows Defenders that have been an issue of sorts - a sort of false negative.

Maybe using the link to the error code 800705b4 which sorted out 2 unspecified problems will have cured the problem?

Many thanks for your interest, PA Bear
