Generic UP.x!hv.g

  The other day I saw that McAfee had found "Generic PUP.X!hv.g" and could not remove it from my system but reported it was not a problem.  Today I decided to try and remove it and find out about it.
  I did a Google search for it and found a site and clicked on the site.  A install window came up and said I needed to installed a program.  I clicked No not to install but no matter what I clicked on to not install it the window would not leave.  I had to close Firefox.
  When I started Firefox back up it went to that install page and I had that window to deal with....
  I never installed it..Well I never clicked to install it.
  I did a re-boot.  
  Most of my programs are missing.  All sort of other problems.
 
  I have now booted up in Ubuntu.  I used the disk burner program to burn the image of Windows 7 to a DVD.
  It just got done but I got the message that some files may be bad.
  My hope is that that message was not correct.
  Well I am going to re-boot and see if I can install Windows 7.
  Even if I do get Windows 7 installed I will have lost all my data and programs that I had paid for etc.
  Have I said I hate Windows?
