After the recent NAV 2007 update, the software virus protection will crash after a few minutes of system start-up. or will immediately crash whenever I start-up Firefox or any other software. I did a system restore and from then on, I have been getting the PIF::AlertEng.dll error each time NAV2007 my PC is startup. I also have ZA Pro running together with it. It had never given me any problems until the last update. NAV2007 still works fine and I can't figure out what the error actually means. Any help will be appreciated. Thanks.
