My server offers NtnAntiVirus free as one of its utilities (one need only uninstall their version and install the version from the server company ... a large Cdn concern ... then install the downloadable version). Option 2 is to upgrade the lic for the present version for 1 yr (about $35 US), purchase NtnIntSecurity+System Works Basic 2006 for $45 or buy NtnAV for $40.
Norton has always seemed such a memory hog. I have WinDefender on board, use a goodly number of the malware programs recommended by GksToGo (Adaware, Spybot ... and used Ewido when it was necessary).
(Another family member uses Avast and as yet ... no problems).
I know none of them are perfect but sometimes it is good to listen to the advice of those who have to deal with the end results of virus/spyware/trojan ... malware intrusions such as does this forum prior to making a decision.
Now the question ... any recommendations suggestions considerations that one might make in making this decision.
