I am having a problem towards typing on the searchbar of youtube (typing delay) and i saw a post that kaspersky may be the problem so i tried the method they suggest which > uncheck the - 'inject script into web traffic to interact with web pages' but it did not work. After that, I removed the Kaspersky extension in the browser and then the typing delay has gone. So my question actually is, is Kaspersky Extension really necessary? Should I add it back or not?
