Hi,
I was wondering what are the best configuration settings for Avast! 4.5 free home edition?
Also, does anybody know anything about a file called: patchinstaller.installer ? I have heard it is a “bad” file.
Thanks!

There is no such thing as best settings. What is best for you isn’t for someone else, so you have to decide on the settings. The help file explains what they do. (start > programs > Avast > help)

For possible settings/options in Avast4.ini, have a look HERE

And that file (including itsBHO address) is indeed harmfull as my BHO util shows.
