Just updated A2 today and found it gave me a new version 1.5. Trouble is when I try and scan it freezes up my whole system for about 2 mins while it loads up the Sigs! Never had this trouble with previous versions. I've tried disabling my AV/FW while loading, but it makes no difference. Also I notice I've lost that rotating A2 logo during scans. What's going on here? Is it worth downloading and reinstalling a fresh copy or are others having the same problem?
