DEFENDER lights.  He tells me it's off and it must be enabled.  I tried several times and I can't activate it.  I see the DEFENDER icon (it looks like gray Castle) in my field of security.  The ICON in my programs (install/remove) is NOT there?  0x80071A90 error message

In ADDITION, 2nd edition: I have an infected memory stick digital camera.  It has infected my computer 4 times from AUGUST 2009 I realized that it was the culprit.  It leads to the DEATH of SCREEN BULE.  He arrived Friday.  I made the recovery of the system.  I REINSTALLED it.  QUESTIONS: What should I do with this memory stick?  Throw it in the trash?  I lost 6 months of precious photos.  Can I move photos or keep the photos?  What do you recommend?

In ADDITION, through the memory stick infect my computer and then the PICTURES who made the infection.  About 3 or 4 flash drives have been put in my computer.  Are they all infected?  I have College CRITICISM of work on one that I can't lose.  What should I do?  Should these flash drives be CLEANED of INFECTION?  They CLEAN themselves without losing me my files stored?  What do you recommend?  I need someone to assess whether or not they are infected?

The infected memory stick infects my digital camera?  And my Photosmart HP ALL IN ONE printer?  Are they ALSO infected?  Will be going to infect my computer.

I do not think that the SECURITY SOFTWARE I have: (free from Comcast) Norton and Microsoft Security Essentials, are fighting the infection from the memory stick.  It would be good to have an EXPERT evaluate the memory stick and tell me what they think.  As well as my flash drives, an expert must evaluate and tell me if 3 flash drives are infected? And they are clean? And the files that I have on them can be saved?

I hope you can help me, THANK YOU, WG

First, you have to run two anti-virus programs.  This is NOT recommended.

Second... you state one of them is Microsoft Security Essentials.  If this is the case, you can't turn on Windows Defender because MSE already made defender and stops automatically Defender because it is no longer necessary.

Difficulty of these 2 things and your problem should be solved.
