Hi Katy :
Long time, no see . So what did you do to make your computer go berzerk ?
After reinstalling your OS, it is probably best to "download" but do NOT
"install" an antivirus program until AFTER getting the Microsoft Updates, since
most likely your computer is SAFE from being infected while connected to
the Windows Updates Site .
But I am surprised another antivirus was "active" while you got those
"Updates" . What is the name of the "another freebie", probably either AVG
antivirus or Avira/Antivir, each of which have their OWN proper Removal
procedure, which I can give references ?
