I am trying avast Pro 4 and Outpost 2.5 at this moment. Can any of you who are also using these two programs advise the followings.
1. How well avast Pro 4 and Outpost 2.5 work on a single Windows XP PC? Is there any conflict you have ever experienced?
Nope. Everything works fine. They should never conflict as avast! is not a firewall and Outpost is not an antivirus
2. I learned that having avast scan the log file of Outpost may slow down system performance. How can you make an exception of this within avast?
I never noticed that but you can:
1. Let the Outpost log file to a minimum size.
2. Exclude it from avast! scanning into the antivirus settings (Exclusions page)
