Hi.
Thanks for your reply.
My Avast Antivirus is the "free"version. Attached is a copy of my nodes. dat file as a (txt file). Secondly, I have been unsuccessful in trying to "purge" (by stopping or deleting - if that's what you want me to do) as suggested.
The method I am currently using at the moment is, not having Avast boot up when Windows starts, so will require me to start the Avast Antivirus application manually. After doing this, I am able to reconnect successfully online and establish a stable connection with my browser properly. Several times, the Avast Behavior shield has accessed my physical memory again. If this happens, I empty my internet cache, and restart my computer using the above method (where Avast does not load during Windows on start up).
Thanks
