I routinely checked the NOD32 downloads page today and found they've got a new build out. v4.0.417. So I downloaded it hoping it would fix whatever problems I had installing the first v4 build. It didn't.
But when I restarted my PC and installed v3 again, I noticed that the system tray icon looked different. So I open the NOD32 window and the whole thing is completely different. I realise I've got the new graphical layout that v4 offers. Weird methinks, how have I got v4 when it wouldn't install and I've just installed v3. So I check the actual build of NOD32 and I've got the old 3.0.684 build installed.
Somehow I've got the v3 engine with the v4 GUI.
Thinking something has gone majorly wrong with my Vista install, Excel spreadsheets take a few seconds to load and even longer to actually let me enter data. CCleaner takes 4+ seconds to load. On a rig running a Q9650 and 4Gb RAM this shouldn't be happening. So sometime over the weekend I shall check what drivers I need to have, wipe the disk and reinstall Vista. Should be OK now I know some tricks with Vista that I didn't when I first installed it last November.
