I recommend these four "free" essential programs to all users.

Spybot - Search & Destroy:

Spybot - Search & Destroy can detect and remove a multitude of adware files and modules from your computer.

Ad-Aware SE Personal Edition:

With the ability to scan your RAM, Registry, hard drives, and external storage devices for known data-mining, advertising, and tracking components, Ad-Aware SE easily can clean your system.

AVG Anti-Virus Free Edition:

AVG Free Edition is the well-known antivirus protection tool. AVG Free is available free of charge to home users for the life of the product. Rapid virus database updates are available for the lifetime of the product, thereby providing the high level of detection capability that millions of users around the world trust to protect their computers.

Surf the Web, block pop-ups, and keep spyware at bay with this lean and fast open-source browser.

Make sure you update all software after installing. :)
