  Please help I found some info, but it's too high-tech for me to understand example go taskmaster > output tab firefox.exe process. may not even know where it is!

  Firefox 4 versions and later, do not run on a PowerPC Mac and require at least OS X 10.5 and an Intel Mac.

  The latest support for your operating system version is 3.6.26 , you are fully updated.

  For more information, see:

  Firefox 3.6 system requirements

  Firefox 10 system requirements

  [For older Mac that are not supported in versions of Firefox 4 +, if you want, try TenFourFox for PowerPC currently running Mac 10.4.11 and 10.5.8]

• Error message says cannot be installed. Try to install again and then inform the producer of the program for the Adobe programs Air & simple gadget.

  Original title: impossible to install adobe air or the brighthouses program simple gadget. Stops at the request...

  "When I download Brighthouses ' easy Gadget", it goes into the installation of the application, rolls 3/4 of the way and stops, which gives a message that it can not be installed. Try to install again and then inform the producer of the program '. Three different agents of brighthouse tried to fix this, but no one could. His attempts to install adobe air in the same time and that will end either. I had both programs (Adobe air) and easy Gadget installed for a year before losing them to a blue screen. Since then I have not been able to relocate. Does anyone know why? Driving me crazy.

  Hi Lou,

  (a) you can completely remove the programs Adobe Air & easy gadget by following this link.

  Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry in Windows:

  How to manually remove programs from the add tool / remove programs

  (b) thereafter, try to download & install programs.

  To download Adobe Air, refer to this link: http://get.adobe.com/air/?promoid=BUIGQ

  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.
