Hi Can I ask if anyone has noticed any system slow down running Superantispyware Pro? Currently, my recommended security system is been Nod32 & AVG anti spyware. Since AVG has not updated their system to run with Vista, it has prompted me to look elsewere. I've noticed though that AVG AS (Plus) does seem to slow down lower spec computers Also I'd like to check if there are any issues downloading updates through Microsoft ISA Firewall? Most of my customers run computers on an SBS2003 network & use ISA 2004 on the server & the ISA 2004 client on the desktops. It seems that AVG AS will sometimes connect to download updates, but will always have problems if there are more than 15 AVG AS computers on the network. Checking with AVG, they say that their product is not supposed to work at all with ISA. If I change products, I need to make sure that I won't get the same issue with SAS.
