From your careful desription of the problem, it seems
like you may have malware on your PC.
Malicious software (malware) can be virus, trojan, keylogger, worm, or anything
that is loaded to your computer under suspicious circumstances.
Meaning, the people who do it, don't want you to know.
It doesn't do you any good.
Just messes up your PC.
I want you to read about how to post a HikackThis log (HJT).
HJT is a small program that shows what is going on.
We read & study the report.
It will give us an indication of what kind of computer you have,
what updates & windows OS (operating system) are involved,
what your browser(s) are and the level of update patches they
have to defend against problem files.
Internet Explorer is probably your browser.
There are others people use.
The tutorial will explain how to run the small program,
how to post the report and where to post it.
It will take a day or so to get back to you.
We will post a reply to the same place you post your HJT log.
You'll learn more that way.
We'll explain exactly what you need to do one step at a time.
You may need to download other programs, and run them, too.
We'll know when you post the report.

You will read that we want you to run a couple anti-spyware programs first.
Doing that will make sure whatever they can't eliminate, we will using HJT.
Each of them is fairly simple.
Download each, install them & make the update first, before you run the scan(s).

Use Spybot S&D 1.3
Use Lavasoft Ad-Aware Personal SE 1.05
& UpdateUsing Spybot - Search & Destroy to remove Spyware from Your ComputerUsing Ad-Aware SE to remove Spyware & Hijackers from Your Computer
I don't think you'll have any problem.
The main thing is to let them fix (by deleting) any problems they find,
and then run the HJT so you can post the log.
Take your time.
No hurry, no worry.
