Well, I seem to have no problems with Avast for virus protection which also integrates itself into Outlook and prevents any trace of those dreaded infected e-mails from being opened. I paid for Adaware SE plus together with Adwatch and the combination of these seems to prevent any spyware from entering my machines. Regular runs of the excellent Spybot utility rarely, if ever find anything untoward. - Or am I just not browsing the "naughty" sites?
P.P.
