Firefox still hangs on file (exe) downloads. A good example of the d/ling problem is trying to d/l ImgBurn from Betanews.com or Softpedia.com. It's a 1.5mb d/l and yet never finishes plus it you'll have to kill the Firefox process. I have left Firefox for up to 15mins and it can only be closed via task manager. As for the copy/move/delete problem with an exe, if I try to copy/move/delete an exe I'll eventually have to do a forced reboot. I'm running WinXP SP2 with all updates. WinXP firewall. NOD32 v3.0.621.0 with: Virus signature database: 2790 (20080114) Update module: 1019 (20071030) Antivirus and antispyware scanner module: 1102 (20080103) Advanced heuristics module: 1068 (20071119) Archive support module: 1069 (20080113) Cleaner module: 1024 (20071217) My machine is a P4 3.0ghz with 2gb ram. It's definitely NOD because as soon as I disable NOD the hanging does not occur. I've spent the last 3 days trouble shooting before I posted this just to make sure it wasn't another piece of software. I also tried the "disable email file" scan and the problem still occurs. All my NOD settings are default with the exception of disabling ThreatSense.
