Let's start by running Adware Cleaner, Super Antispyware Free and an Eset online scan.
Post the logs from the scans back here. Allow those scanners to remove whatever they find.
SUPERAntiSpyware.com - AntiAdware, AntiSpyware, AntiMalware!
Free ESET Online Antivirus Scanner
Hopefully one of those will find and remove the cause of the ads. If one is successful, then
use Ccleaner to clean up the temp files, logs, etc. Just use the default settings. Do not use the
registry cleaner. Not necessary and may cause problems. While installing the Yahoo Toolbar or other
will be offered. Be sure to UNcheck the offer unless you want it.
EDIT: CCleaner - PC Optimization and Cleaning - Free Download
If you are only seeing those ads while visiting one particular website, then it could be as simple as
blocking third party cookies. Disable third-party cookies in IE, Firefox, and Google Chrome | How To - CNET
After blocking the cookies from installing, you will need to run Super Antispyware to remove the ones
that are presently on your computer.
If you are using the Firefox Browser then install two add-ons....Adblock Plus and NoScript.
Adblock Plus can be installed in Google Chrome, too.
