Thanks for the answer.
I am just curious because I just installed OnlineArmorFree Firewall and noted that the free version does not protect against keyloggers.
I am so pleased that AvastHome does protect against Keyloggers--this is such a great app. I have been using it on some modern and old computers and it works equally well.
The other day it caught two trojans when I was downloading some files--he sirens went off, it stopped the download, and asked me what to do. It was a very dramatic moment. It felt so secure to know that Avast was there when needed. Woefully, my other antispyware realtime app didn't even notice that the trojans were entering the system.
Thanks so much to the Avast team and all the helpful volenteers that contribute to this forum.
