experiencing the symds.sys BSOD mostly during the nighttime and probably when it is scanning .
had tried some solutions before ...but after a period of time it is returning.
having troubles with this failure for approx a 8 or 9 months on and off now .
running XP
pentiumD2.66
2 Gbram
internet security 2010 updated as described !! is now version 17.6.0.32 NL
but still it keeps shutting my system down overnight.
