Re: IE Malware / Spyware Control Methods

[Chris Krough <ckrough () vet upenn edu>]

Following the concept of least privilege is very effective at preventing 
spyware installation. We've reduced the access level of most of our 
users to 'Domain User'. For users who require frequent administrative 
access we provide them with a secondary, preferably local only, 
administrative account. For users with occasional administrative needs 
we either upgrade their account temporarily or just perform the 
installation/changes ourselves. This practice has almost completely 
eliminated spyware problems from our network.

Depending on your users needs there is a good chance that lowering 
default account privileges will increase the load on your support staff. 
Installations and low-level configuration changes will require attention 
from someone with administrative privileges but the time saved over 
handling spyware/virus incidents is greater.

Have you upgraded your clients to XP SP2?
