Excellent video as always, and informative. The several year old version of Comodo firewall is still solid protection, which does not surprise me. It's tempting to reinstall it on this machine since I bit the bullet and moved up to Win 10, leaving my beloved Win 8.1 probably for the last time. I think, though, I'll wait for the new Comodo, if it ever comes. Kaspersky is serving me well.
