Years ago I used ESET Smart Security on a Windows Vista pc, but didn't much like the behavior of the firewall and the overall operation of the system. So for the last four years I had not used ESET on any of my computers. Even with reading recently some of the concerns about the latest version, I purchased a subscription of NOD32 for one of my Windows 7 (64-bit) pcs. So far, I am very impressed with its operation. Thorough and quick scans, no slowdown to speak of, simple but elegant GUI. Internet connection is fast on startups, etc. I like this much better than Smart Security, as I believe Windows 7 firewall is good enough. I also have a paid version of Superantispyware as an extra layer of protection. I don't know, I feel confident and content with ESET. It just seems like a very good choice for security protection for this computer. But I wonder about their customer service. How is it? I know about the forum here, but can you really get through to speak to someone, or is their turnaround decent on email queries? Thanks.
