Recently (for the past 2 or 3 days) the popup window "DT Properties" occurs on startup. I have no idea what prompted this, but while I don't notice any significant performance decrease (which, I assume, can rule out a virus), it does get quite annoying.
I click the 'Restore' option, but to no avail.
I have attached a screenshot of the popup window on startup.
Any help would be greatly appreciated!
