Hi, I have recently upgraded to 64bit windows xp. On 32b Win I was using free AVG. Now with x64 win i decided to try nod32. I have installed (trial version) it directly after installation of windows and all the drivers. I was experiencing very random restarts (maybe 1-2 per day). Usually while browsing in opera, or a bit more often while playing Flatout 2. I thought it's a driver issue... but after a week or so i have discovered that NOD was the cause. Were there similar problems in the past with nod? Or is this maybe know bug and there is some fix or workaround? So far I really like nod, so i would really appreciate any help. Thanks.
