The thing is, when you download "customization tools" free from the internet, or when you download free security programs from the internet, or when you run multiple security programs all at the same time:
you can expect nothing but problems.
Most of all, avoid any free downloads, especially the ones that claim they will fix, clean or speed up your computer. These types of free software are a scam, to plant spyware in your computer.
You will learn that, someday.
A. Delete all free downloads, especially the ones you already named, restart.
B. Insert win 7 install disk, select: "upgrade"
C. This will reinstall the operating system, without erasing your personal stuff.
D. When your system is running normally again, install a professional all in one security system. This WILL NOT be a free download.
E. activate, update, and scan entire computer with your professional security.
Now, if you can resist installing more free junk programs, your computer will probably work just fine.
