My new Dell Precision m4600 (i7 quad, 16gb ram and 256 SSD) came yesterday and I have spent hours trying to figure out what was causing a problem as I slowly added my programs and application to the Windows 7 x64 OS. At a certain point the laptop would boot up to the login and then hang on the Welcome screen. At first I assumed it had hung up and after two complete restores I went through a more controlled install of the 30 windows updates, Chrome and the new Nod32 install. I discovered that the problem occurred after Nod32 was installed and the system was not really hanging but took 8 or 10 minutes to get past the welcome screen (considering with the SSD an normal full boot took less than 30 seconds without Nod32). Suspecting HIPS I turned it off and had no problem. I then ran it in interactive mode to try to manually add programs to the ruleset. After a number of still long boots, the wait was down to 6 minutes. I than turned off only the Self Protection and - back to normal sub 30 second boots. I've been a long time user of Nod32 (almost since the original release) and still think it by far the best anti-virus software but this was really annoying. Has anyone else seen this and any fixes? Perhaps the SSD is too fast for it!
