"Very good! It immediately found Bookmark Sentry, Timestats and WebpageScreenshot as being malicious, and I know for certain that Bookmark Sentry is malware as when it's activated, it keeps trying to open pages linking to dodgy versions of Flash. Definitely worth an install!"

"Awesome!!! The Chrome browser in my Mac somehow got some malware in it for the first time in 2 years. AppleCare couldn't locate the origin. But I think that Jonathan H. got it because the problems began right after I downloaded BOOKMARK SENTRY, as well as HOVER ZOOM! I hope that that'll be the of that malware and that this extension will prevent any further!"

"I've had this extension for a while now, and it has successfully identified malicious add-ons/extensions that compromised my security."
- Chrome Webstore

"Works great to prevent malicious extensions - this is essentially an anti-malware extension to prevent bad behavior from other extensions. It's been added to my toolbox of security and privacy add-ons. I'd like to thank the developer of this extension for filling a much needed role in protecting Chrome from malicious extensions!"
