Hi, Just installed a trial version of nod32 to replace mcafee which used too many resources (caused weird pauses on my system - a t42p). When imon is enabled, firefox just won't work. Resource usage spikes, pages don't load after firefox opens, and I need to shut it via the task manager. I've tried disabling the http scanning, changing compatability modes, repairing winsock, but no dice. Can anyone help? It's fine to tell me to switch to KAV. I'd prefer to stick with NOD32 - it seems very trim, and I like that. I just want that imon to work. It seems important enough to use. If I can't get it working soon, I guess I can try out KAV, which is resource-heavy, but perhaps won't cause the resource spikes that Mcafee did. Thanks. I've also had troubles with updates, but I see in another thread here that's just the trial version that has a "dumb" updater. Will it also update the engine over the next month for me?
