You're using Windows 8 Pro but you use M$ Office 2007 ? interesting...
Does this sandbox all downloaded files? or is this pro only?Hi,
Try to find a backup software, it's always useful, then, since you don't use any add-ons, I suggest you a sandbox for your browser
2nd Browser IEI have no question to QuickHeal, the performance is quite good from most common threats.
Anyway fine configuration out there, consider to have a backup browser.
