Using the uninstall feature in the Add/Remove Programs in the Control Panel will not work, so you need to do something else to get rid of this nasty software.
This should work, if not, please post below, and let us know where what went wrong.
- Run "regedit.exe"
- Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows
- On the right-hand side you should see a String called “AppInit_DLLs†with a value of “pushow*.dll†where * is a random number.
- Right-click on this String and click Delete and then exit regedit.
- Open "C:\windows\system32\"
- In that folder there is a file called "pushow*.dll," where * is the random number you saw above. Delete all pushow*.dll files.
