It's not important if it's upper or lower case. Makes no difference.
Why not remove/delete/uninstall that program in stead of block it?
Or at least, don't run it when you boot. That's a setting in Task Manager (in Windows 10) or msconfig (in older versions of Windows). If it doesn't run, you won't get that message.
Occasionally, not every time I log on to my laptop, I get this message flashing up on the screen, telling me that it is blocked by my anti-virus software. I have no idea what this is so I checked on your forum where questions of this type are posted, and I noticed that someone had said that it should be typed correctly, "Itibiti.exe" and not "itibiti.exe", yet on the blocked notification on my laptop it comes up with the latter spelling. Does this mean that it is significantly damaging in that it is different to the Itibiti.exe or is it the same thing? I'm happy to keep it blocked but want to know whether these are one and the same thing or whether one is legitimate and the other may not be. Thanks.
