I'm currently running NOD 32 v 4.0.437 and I've noticed that there's now an updated version available. I'm a bit mystified by this, since I've seen NOD tell me that program modules have been updated in the past few weeks, so I know it's been updating signature and program files OK - But I'm still running on an outdated version somehow? Additionally, I've noticed that several people have noted that the most recent version of v4 has weird problems saving files. I'd not like to encounter that. So I suppose my questions are (1) is it safe to be running on this older version of NOD v4, or am I unprotected from some threats and/or exposed to bugs and flaws that are fixed in the upgrade, and (2) how can I ensure that NOD updates itself properly? Also, as an unrelated question (since I don't want to open two threads!) what Antirootkit software plays nice with NOD v4 on Windows 7 x64? Sophos was the only x64 compatible version I found, but it doesn't seem to run despite claims of compatibility. I've seen Avast Antirootkit, but I'm not sure if it's a stand alone scanner, or a full A/V package that will conflict with NOD. Any help would be appreciated. Thank you!
