• How can I reinstall Windows Defender on my laptop HP Vista 64-bit?

  Bots and a kind of virus/hacker got in and everything moving & ripped off many drivers needed for important security programs such as defender and Trend Micro Titanium, Ran Malwarebytes and Spy - bot Search & Destroy, but nothing came.  Responsible for Microsoft Security Essentials and who is working for a little time, and then when the computer restarts after updates through Windows Update, Security Essentials is disabled, just as the Defender is always, it seems!  When I try to start it (Yes, as an administrator!) until you get the error code: 0x800106ba and display hangs.  I try to save almost 4 000 photos stored on my laptop and transfer them to a new external hard drive, a few buddies very attentive gal of my friends bought for me (I'm home with AIDS and the very limited income, so it really sucks if I can't get my main source of social interaction, news) creative and well stuff even more upward and running the way it should have been when I bought 2 years ago!).
  I digress from the subject, sorry.  In any case, I downloaded the Defender, called Windows Installer: Defenderx64.msi Windows and when I run I get another error message that says that the Defender is already loaded and to reload I must uninstall Defender. and when I try to it says I can't because he shook in Vista, somehow and not repairable.  Please advise!  JSB

• Windows Defender will not be updated

  I am experiencing strange shift of internet and I think it's because Windows Defender won't be able to update. I am running Vista x 64 final. I recently started to receive a new error every time I start my computer, something to the effect of Windows Defender service is unable to start. If I try to start it manually, I got the error: 0 x 80070003: the system cannot find the path specified.

  Normally I wouldn't complain about windows Defender does not because I have my own solutions, but I believe that it is still problematic within my system. Every half hour or so, my firewall warns me to say that something in a temporary folder called mpistub.exe or something is trying to access the internet. I found this exe is a windows update, so I allow it through. Now, I believe that because the service cannot start, the update is impossible to apply and continues to go to the internet to try to get a shift to internet update, causing news for my pc everything.

  Someone knows something like that? I would like to reinstall windows Defender so that it can update itself and let my only internet. And I don't mean simply turning on or off; I can't do this if the service does not start. Oh and I tried to restore to an earlier date, it is not far enough.
