I'm using a Dell XPS M170 laptop with 2 GHz processor and 2GB RAM, and WinXp Sp 2. I'm using NOD32 v 2.7 with the latest definitions. I'm getting 3 to 4 seconds of lag before I can do anything on a Web page in Firefox 2.04. Scrolling down a page, sliding the scroll bar, typing text in Web forms (such as this), selecting a bookmark, anything at all. I've noticed that hard drive access seems to accompany this, and from what I can tell it must be either AMON or IMON scanning files on the fly. I've reset Winsock, but that wasn't the answer. I've also set my apps to Higher Compatibility mode in IMON/Setup/HTTP, but that didn't fix it, either. I've been using NOD32 for a few days now and thought it must be a configuration problem, but I've been through the FAQ and tried various tweaks, bu the problem remains. I experimented with IE 7, which I don't normally use, and it was not affected by this lag issue. I also checked for background apps and processes that might be using excessive CPU or RAM, but didn't find any. This problem definitely coincided with my installation of NOD32. Any help would be appreciated.
