Win 7 takes 15 minutes to boot

Okay I ran check disk it rebooted and 10 minutes into the scan it showed that 1/3 of scan completed and that it couldn't read four different sectors .

but below that it said file verification is completed . 247,000 files processed . 1000 large files processed

I walked away and came back 1/2 hour later and the computer has rebooted . So I don't know if I'm going to be able to see the results when it reboots in the event manager thing, as last time I tried this I couldn't find any results there.

If it boots fast in safe mode, is one of the start up programs.
I also have Avira (free) and it works well.
What you can't have is two antivirus. You have to uninstall one of them. (avira or MS essentials).

. Fair enough but does the antivirus start in safe mode? . The second question I have is avira has been installed on this computer (my friends by the way ) for two years , apparently always coinciding with Microsoft security essentials, why all of a sudden the problem ? Also, I have friends who for some strange reason deliberately run two antivirus systems without incident
