I recently installed the trial version 4 of the ESET NOD32 together with the recent release of free Zonealarm firewall. Unfortunately, after installing the two, my unit experienced random reboots.. And it happened many times. Im suspecting the NOD32 because I installed the ZAF8 first without experiencing a problem. As the NOD32 followed, there appeared the problem.. I reverted back to NOD32 v3 and without uninstalling the ZAF8. My unit is Okay now..
