Hi - My Avast started playing up for some reason (it was getting very slow when I was searching) so have decided to reinstall. I understand that it is not advisable to download and install Avast whilst there is another Antivirus and Firewall running.
Surely, if I go online to download and install Avast without any protection, I am asking for trouble so how can I safely do this???
Once you have downloaded it, go off-line. You should then be able to uninstall the other AV and install Avast without intervention from the other program.
