I am using avast! free edition and I want to install a firewall or hips to improve security.But no matter what software I install(e.g. look'n'stop,mamutu,threaten fire),there always is a green screen when I boot my computer.It indicate that aswSP.sys leads to the crash.This file is avast self-protect module.I hope next edition could fix the problem.My avast! version number is 6.0.1125,OS:winXP SP3
