OK, so here's my story: I'm running Vista x64, and I have a license for KIS 07 good until 2010 which I received through a promotion. HOWEVER, I'm tired of KIS slowing down my connection and taking 30 seconds to load certain web sites (anandtech forums for a popular example). As of right now, I'm running my NAT router and Comodo, along with SuperAntiSpyware (paid). I'm quite happy with SAS, but Comodo and Avira just don't seem "polished" enough to make me feel safe. Over the past few days, Comodo has crashed randomly about 6 times, Avira's icon randomly disappears from the taskbar on windows startup (fixed for now), etc. So, that leaves me looking for new software, even if I'm going to stick with my current config, to make sure I covered all my bases. I'm debating going back to Outpost's firewall (which I had before KIS, on XP), as they were rated as high as Comodo recently. Once I edited a few rules, Outpost ran smooth and gave me no problems. I was also looking into NOD32, which I had paired with Outpost, but the whole proxy web scanner business scares me off completely. So... Is there an AV that has excellent real-time methods of keeping viruses OUT of my system, can reliably get something that leaked through, can protect itself from malware shutting it down, is light, and doesn't slow my system down? It's a pretty damn beefy system, so the fact that kaspersky bogged my browser annoyed me to no end. A fast scan is a PLUS, but frankly, I run scans weekly, and it's almost always overnight, so I don't care if AV1 can scan in 40 minutes, while AV2 scans in 90 minutes. And please, let me know if I'm chasing an imaginary product here... So far, I can't find anything that fits the bill. Edit: Thought I'd mention, I'd prefer a HTTP scanner capable AV, but between the NAT, and Comodo's HIPS, is it neccessary?
