Does Avast identify them selves w hen they return a call from support over the phone.
I ask because while trying to resolve a issue on my old windows XP computer I was receiving erroneous calls that concerned me. Thanks
Most, if not all, of us recommend you never use the third party support.
For best results post your issue here in the forums. We are user volunteers
dedicated to assist others with their issues.
We know you have an XP. Which SP?
Other security software you have now or ever had?
If uninstalled how was it removed?
And tell us about your issue.
