Standard disclaimer: I can't see and test your computer myself, so these are
just suggestions based on many years of being a professional computer tech;
suggestions based on what you've written. You should not take my
suggestions as a definitive diagnosis. If you can't do the work yourself
(and there is no shame in admitting this isn't your cup of tea), take the
machine to a professional computer repair shop (not your local equivalent
of BigComputerStore/GeekSquad). Please be aware that not all local shops
are skilled at removing malware and even if they are, your computer may be
so infested that Windows will need to be clean-installed. If possible, have
all your data backed up before you take the machine into a shop.
