When did NOD32v4 (Antivirus and AntiSpyware) first come out of Beta? Is the current build, 4.0.314, the first one since Beta, or has more than one build come out since v4.0 came out of Beta? I've gotten a lot of advice to move up from NOD32 2.7 --- not for the new user interface (I'm used to the old one, although initially it drove me crazy), but for better AV and Spyware security. I've now got the time to do the upgrade (after first making a backup image of each computer's C:\ partition). I'm debating whether I should go with the latest 3.0 version (3.0.684), or jump ahead to 4.0.314. I use Windows 2000 Sp4 Rollup1 v2, and I expect to stay with that OS for the foreseeable future (even though Windows Updates for Win2k will die in 2010), because I don't have the time to clean-install and then learn a new operating system, and to reinstall all of my current software. The only network I have is a Workgroup (peer-to-peer) home and home office network of four laptops, only three of which use NOD32 and would get the upgrade (the fourth one acts as a print server and is a Win98se with a 4gb hard drive and 96mb of RAM). There is no domain server-client network anywhere in sight. The three "real" machines have 40gb hard drives with lots of spare room, but only 1gb of RAM. All computers use Mozilla's Spysweeper browser and email (descendant of the Mozilla and Netscape suites). I'm not considering the Smart Security Suite because I'm quite happy with my Danware NetOp "driver centric" firewalls v4. Is there a NOD32 comparison features list, v3 versus v4, available anywhere? I'd appreciate any comments, suggestions, or advice I can get. I do NOT want to slow my computer operations noticeably below what they are with NOD32 v2.7. Roger Folsom P.S. For Anti-Spyware I'm currently running Webroot's SpySweeper 188.8.131.52 which is the last Win2k version that will be available, but my subscription doesn't run out until 10 July 2010. Can NOD32 3.0.684 or 4.0.314 and Webroot SpySweeper run (i.e. be monitoring) simultaneously, in "real time"? For demand scans using either one, I do shut down the other program. The NOD32 3.0.684 Quick Start Guide and User Guide make clear that you cannot run NOD32 and another antivirus program simultaneously. But in those documents I haven't seen a similar statement about NOD32 v3 or v4 and another antispyware program. And in years past, running multiple (at least two) antispyware programs was a common recommendation.
