I cant browse chrome or explorer

[REDACTED]

after avast has been installed to my computer I cant broswe chrome or explorer, becouse I cant open images, or links which I could open when there where no avast in my computer. If this wont change I am surely will delete it from computer. aND I wanted to pay for upgrades...well admin I hope this will change!

Was this a clean installation of ONLY Windows or from a recovery medium?
If it was Windows only, did you install ALL drivers for the system?
What Windows version?
What EXACT avast version?

I had similar issue when I updated my Avast. I use Windows 7 so not sure if this will help you, but this is what I was told to do. I did this and can know open my Internet Explorer browser and go from there. Hope this helps you.
