I have built a new Windows XP Pro SP3 PC and want to run "Lean" while still having good security while browsing the web. My only web access so far has been for Windows Update and Microsoft Office Updates. Current Setup: 1. NOD32 version 3.x Antivirus (with BlackSpear’s Recommended Settings xml Configuration File Loaded, Configuration Password Protected), 2. Windows XP SP3 Firewall On 3. SuperAntiSpyware Free Edition 4. Sandboxie Paid (All Web Browsers Forced into “Sandbox”, Only Web Browsers and Windows Media Player Allowed to Run in Sandbox, Auto Delete Sandbox Contents on Web Browser closure) 5. SpywareBlaster. For the time being I have decided to leave off the following: Microsoft WindowsDefender, Ad-Aware 2008 Free Edition, AVG Anti-Spyware Free Edition, Spybot Search & Destroy, MalwareBytes AntiMalware and a2free 3.5 AntiMalware. Plan to add: 1. FunkyToad’s HostsXpert (For Window’s Hosts File Management) and the MVPS Hosts File (with routine updates). I also will disable the Windows DNS Client Service to minimize the load on the PC caused by numerous entries in the Window’s Hosts File. 2. When a2free 4.0 AntiMalware is released in a few weeks I plan to give it a try. Does anyone have any suggestions for additions/deletions? I have been thinking about HIPS and/or HIPS-Firewall such as Online Armor. I also plan to try out Paragon Disk Backup Personal 9.0 in the near future. Thank You in Advance.
