For the last month or two my machine (Tecra M5, 2 GHz, 2 GB Ram XPP sp3 fresh install about 6 months ago) gives a message that "Your computer might be at risk" during startup which goes away (and Firewall turns on) as it finishes loading. I spoke with NAV and uninstalled NAV and reinstalled (and updated to NAV 2010 at same time.) No change.

I have read that this could be related to start up programs and the order in which they load, which I've never had much luck adjusting other than unchecking in msconfig or using a third party software (and I didn't see any difference then.)

I have not been concerned until recently when one of the online programs I use upgraded and during one of the operations it locks up my browser about 1 time in 3 (IE 7 my machine runs slower on IE 8.) It does seem to behave properly if I've just run diskcleanup. This program is called Tempo 5 and it has very heavily java programed database quireies, etc.

Any thoughts?
