Have been using SE4 for a year. Installed 5.14 last week with no problems and am just now starting on the tutorials.
So - 5.5.16 just arrived. I downloaded it so I could stay abreast of the innovations.
My anti-virus (BitDefender) tells me "
File C\Program Files (x86)\Light-O-Rama\LORVerifier.exe is infected with Gen:Variant.Bulz.199282 and was moved to quarantine."
The SE5 installed stalled due to (I assume) the the file being stashed wherever BitDefender put it.
I fully uninstalled the existing LightORama software and tried installing it again - same results.
