I am running NOD32 3.0.695.0, Virus signature 5758, on a WinXP Pro SP3 system with IE8 and Office 2007. During the past few days I have been getting MS error messages to the effect that Outlook 2007 had to shut down because of a problem with NOD32. Today when I restarted Outlook, I got the following: "Outlook experienced a serious problem with the "eset outlook plugin" add-in. If you have seen the message muliple times, you should disable this add-in and check to see if an update is available. Do you want to disable this add-in?" During the past few days I have also begun to have IE8 hangs, and one complete freeze, also shut-down problems, some requiring a hard shut-down. I have made no changes yet, and after reading this thread, I am reluctant to install Version 4. Any suggestions for at least a temporary workaround? I don't actually know how to disable the Eset plugin in Outlook.
