It is best to run the Spy Ware Utilities in [b]Safe Mode[/b] so you can remove any infections but make sure that they are updated first so that they can destroy all the infections that you have picked up along the way. Just be careful with Spy Bot S&D as it is capable of crippling some of your used programs so look carefully at what it picks up and if you see anything that you are using untick it things like Windows Defender and some On Line Banking Programs are the most likely culprits though some Internet Installed Software can also be picked up along the way.
Most often however when you have problems with installs that don't last long it points to a HDD failure occurring as the drive slowly fails. But if you are not employing any Protection from Virus or Spy Ware you can expect about 5 minutes of Web Browsing before you get hit with an infection so you really need to stay on top of these threats.
