I installed NOD32 today, everything worked fine, until I rebooted: everything froze, even task manager. I did a hard reset, rebooted, same problem again. I then rebooted into safe mode, and uninstalled NOD32, rebooted normally; now the system is stable again and everything is working fine. I suspect NOD32 somehow causes a conflict with the networking stack which is installed by cfos speed (I'm currently using V4.21 build1 403 ht tp://www.cfos.de/beta/cfosspeed-v421-build1403.exe ). I've seen some other threads (in the cfos forums) which indicate there might be some issues. Can anyone else confirm this?
