Hi Caos, just to update you on my problem. You last asked if I had Office 365, actually I did not had it installed but was using it via browser. So I decided to look into the OneDrive storage and the potentially infected file was there, so I deleted. It looks like this resolved the issue? I no longer see the warning so I assume trojan is gone, hope so! One last question if I may? I did save the file to my desktop and then use Kaspersky to look for a virus, nothing found and that confuses me, should it be found there? I’m just curious about this it could be that there was macros on this file (Excel) that made Kaspersky think there was a Trojan? Anyway, many thanks for your help, most appreciated. Kind regards, Jose
