Zedo is an adserver program that is set up as a service to pop up ads on your screen. Since it is a service type program most spyware/malware programs are fooled into believing that it is purposely installed and as such..they will not uninstall it.

This fix contains a Registry edit and if done wrong can cause harm to your computer!

2) Click on Start, Search, and choose All Files and Folders
3) In the all or part of file name box, type the following


4) In the Look In box, choose local hard drives and click Search
5) When core.sys is found in the c:\windows\system32\drivers directory,
right-click on it and choose Delete
6) Repeat steps 2-5 for the file


7) Close the Search box
Click on Start, Run and type REGEDIT and press Enter
9) Click on the Plus sign (+) next to HKEY_LOCAL_MACHINE
10) Click the plus next to SYSTEM
11) Click the plus next to CurrentControlSet
12) Click the plus next to Services
13) Find the folder called CORE and right-click on it and choose Delete

*** WARNING *** If the folder CORE does not exist, dont do anything

14) Close the Registry Editor by clicking on the X in the right-hand
corner of the window

15) Reboot your computer in Normal mode
16) Once the computer is rebooted, Run all your anti-adware/spyware utilities
