When you try to install Office you get an error message that the install fails and signature verification can not be completed.
When looking in untangle you see that virus blocker lite has new hits:
virus_blocker_lite_name
Win.Adware.Browsefox-12535(0122bab0a42f8dcb58553c1844478dd0:18299931)
Disabling virus blocker lite allows for the install to complete.
