We just installed in our Windows 8 PC an update from Comodo. For some strange reason, now all updates forces you to either check-mark 'yahoo search engine set as default' or an option that protects against malicios software. We can't installed until we check one. Since the malicious option we done need, we are force to check yahoo.
The problem is that we have all set to google. So in order to install comodo update, we had to choose yahoo engine.
How can i change all search engines configurations back to google?
