Can Google Chrome cause a virus?

Yes it does. There is no root kit protection for the browser and therefore your network becomes a back door for anyone who likes to drop trojans, etc. Also, google Chrome is part of the Pentagon's Cyber Task Force. Everything you do on Chrome is monitored very heavily. All of your personal information, sites visited, files downloaded, etc, are all stored on a cloud server that is constantly scanned for "malicious activity". Basically, if your using Chrome, you have zero privacy while Surfing the web. And it's slow as molasses.
