Hi there, I've been searching and trying out different combinations of layers to secure my XP32-SP2 PC as good as possible, with a minimum of resources taken by them and not too much questions constantly popping up (like for example Comodo V3 with defense+, which I really like, but is too 'present' for me). Currently I have running: Realtime: Nod32 v3 PC Tools Firewall Plus PC Tools Threatfire Ad-Aware beta 2008 (with ad-watch running) I also have a license for Norton Antibot, but not currently installed because I read on different places that Threatfire gives the same kind of protection, but better .. I don't really know if this is true. Also Outpost Pro-license, but I think it's too 'heavy'. On-demand Spybot & Destroy F-Secure Blacklight SysInspector AVG Antispyware Preventive: Router (With Firewall on) Firefox (no extra security add-ons, don't really want them) Thunderbird All latest updates (XP and other software) Spybot & Destroy Spywareblaster Secunia Software Inspector Microsoft Baseline Security Analyzer CCleaner and other (registry) cleaners MVPS HOSTS File My question here is: Is my machine protected enough this way for all/most existing different kind of Threads/malware, or would someone recommend me to change something in this setup? PS: SAS always seems to find nothing on my PC, so does A-Squared, tried them both. That's why for antispyware on-demand I only use AVG Antispyware now..
