a warning about Avast Business Protection: i tried to install it but my computer frooze.
i had to do a "hardkill" by removing the battery from my laptop...
i restored my system-backup and tried again, on my second attempt it once again frooze,
but after a while it finished the installation.
then i got an errormessage: "trial expired"....
i restored my system-backup and tried a 3rd time, but it frooze my computer once again,
so i finally gave up....

so if you´re thinking about installing it, then perhaps you should continue (to think about it).....
if you´re going to install it, then i suggest you make sure you have a good systembackup before you go ahead, because Avast Business Protection seems to have some problems with R2....

Avast, AVG, and Avira blow big time. They are free for a reason.

ESET NOD32 AntiVirus 5 works like a charm on server, with Orca trick. Let me know if you need help on how to get workaround to work if you are interested in installing ESET NOD32 Antivirus 5.

Does Avast 7 work on R2 ?
Last time i tried Avast it didn´t work normally....

Thanks for the tip about ESET, but at the moment i don´t plan to install ESET.

Yes, Avira works, but i got some minor problems that i suspect was caused by Avira, so i temporarily uninstalled it.
But i´m going to install Avira, just to see if i get those problems again...

I´m currently using Forefront Endpoint Protection together with MBAM, and so far they seem to like each other, using mutual exclusions.
