A few days ago I downloaded the Kaspersky Security Cloud – Free edition and allowed it to install it’s extension on Chrome. It didn't take long for me to notice that it didn't work very well, for example the CPU usage jumped to 80%+ when I entered certain sites. Then I removed the extension. What I want to know, if it is normal for when I search on Google for there to be green shields (URL Advisor?) even without the security extension installed.
