hi, i've downloaded the avast home edition and after that, I cannot open any websites in firefox or internet explorer? When I uninstalled it, then I can open any websites! I've done this twice already, downloading and removing it! Why is that? I'm using windows vista home premium. How does avast work? When I bought my toshiba laptop, it came with the McAfee security trial and it has expired already. Maybe I have to uninstall McAfee so that Avast can work? I would really appreciate any response on how to go about this problem. I haven't downloaded again the Avast home edition until I know how it works. Thanks!
