I just upgraded from 2.70.39 to 3.0.650 and I'm really pleased with the result. I noticed a big improvement in scan speed, and the new user interface looks great and is easy to use. The on-line and PDF documentation is complete and well written. One of my computers is an old 400 MHz laptop with 256 MB running Windows XP. Since I was removing and reinstalling NOD32 anyway, I decided to check out AVG 8.0. With AVG installed, the laptop was so slow that it was useless. With NOD32 it runs fine. Thanks to everyone at ESET for a job well done!
