We know Google isn't afraid to make it rain for the sake of Chrome's security, but today's provisions appear to be an inside job. Laying the smack down on toxic browser extensions, the company introduced a new set of security measures that label applications in violation of its safety guidelines as malware. These potential threats try to bypass the browser's silent installation blockers by manipulating its management settings. Once installed, the malicious software is enabled by default and cannot be removed or disabled from within Chrome. Google cautions that within a week people will begin seeing download alerts when attempting to install an identified threat. In the meantime, we suggest you start making plans to check out your current extensions just to be sure your setup has a clean bill of health.
