Did AdwCleaner find anything?
What you can also try is uninstalling / deleting the wifi driver, and then trying to reinstall it. It's possible it's a corrupt driver. You can do this by going into Device manager -> right click your wifi device -> Uninstall... -> check the box mentioning deleting the driver file as well -> Click OK -> Reinstall driver.
