I've been trying a number of free trials, free software, etc...and am now attempting to put together a realistic and affordable protection system for 3 computers (1 on XP Home, 1 on XP Pro) and a HP Notebook running 32 bit Vista Premium. First...I paid the $5 x 3 for A-Squared. Now, I'm looking to pay $49 for Outpost Security Suite which will cover 3 machines for a lifetime. I have also downloaded Sandboxie and will probably buy that as well since I can run it on all three machines legally. Retunil also has a freebie going on, but I'm not sure that it's needed for our type of computer use. Sandboxie is pretty cool however, in that we can run Firefox through Sandboxie and flush the box as needed. I assume that most malware is "surf" related, so this makes sense. Machines all hook to the internet behind a D-Link N router. Computers are used for a variety of reasons...college work, desktop publishing, website maintenance, a fair amount of online gaming, browsing the web, etc... Not all family members are "up" on security protocols, so I need something pretty easy that runs behind the scenes. So... Outpost Security Suite (to purchase with New Year Special) A-Squared (already purchased for $5 a machine) Sandboxie (probably will buy this as well) The other choices are many...but so far, these 3 are working well together without any appreciable slowdowns, blue screens or apparent conflicts. My budget is basically $100 for 3 machines. If there are better combos, please let me know before the Outpost "special" expires Thanks for the help.
