Since I last update avast chrome was not starting and kept opening various pages and e unresponsive. Nor did mozilla but at least the last time I tried and partly succesfully opened mozilla it told me it was crashing due to avast trying to installing plug-ins and that is how I figured out that it was not just chrome being fussy but that something had gone wrong with the avast installation.
The funny thing is that avast safe browser was installed as the other components, this is based on chrome, it seemed to work just fine while my normal chrome kept not responding. This made me feel like avast was forcing me to use "their" browser.
I am very unhappy about this, I feel lucky I didn't install any plug ins for my least favourite browser, internet Explorer. I idownloaded another antivirus in case I needed to completely unistall avast.
I have unistalled the browsers plug in and the safe browser... finally both chrome and mozilla works without having to reinstalling them. You have to improve something here because it's only out of luck that I didn't update or install plug ins on internet Explorer and I was therefore able to look up for a solution (which yes it was inspired by this forum). I am not a computer genious so the reason I am writing this is for people like myself.
