this is my first post here,and I'd appreciate any help.
Norton 360 found I'm infected with Boot.Tidserv.b
I couldn't see any problem expect bluescreens-shutdown-restart,the last two weeks.
sometimes it happens repeatedly,sometimes once or twice per day.
I tried Norton's special tool (FixTDSS.exe) which didn't find anything.
But I wasn't able to turn system restore off,before that,according to instructions ,
because I can't check the box(it's grey),and I can't set a new restore point too.
I hope you can help,
