And some other questions ( pertaining to the full version ) : - What happens after the 30-day trial expires ?? Does TDS become completely useles ?? - What EXTRA features are present in the fully purchased version? Opposed to the demo or trial version . - I have two computers in my home , do I need to purchase two licenses -one for each ) to install TDS on these ?? - in the trial version it says I need to download latest signatures even though I installed the very latest version from the site , is this a DEMO/trial thing ?? I have loads of stuff running in my systray ( going to list this in a se ) , is anything known about any conflicts between TDS and these apps ?? - Kerio personal firewall - MS Anti Spyware -Spybot S&D - Spyguard -Spywareblaster -AVG 7 PRO The only thing missing seems to be a good anti trojan program and this seems to be the works - but I'd like the questions answered prior to deciding whether or not to purchase .Also : Does TDS work with a yearly sunscription fee ( or will the new TDS 4 ) or is the purchasing pricce "all-in " Like this forum, by the way .
