While I was programming my EV3 robot on my Windows 10, the Lego Mindstorms software immediately closed, and then Bitdefender Antivirus said that it was some sort of Ransomware. It was Bitdefender that closed the application. It looked like this:
Clicking on "attention required" then shows the following:
So then I pressed "Restore Location" and stored the file into some random directory without even knowing what I was doing.
Now I don't have this problem anymore, but I seem to be the only person who has ever had it. And I also wonder why MSIMGSIZ.DAT is needed for the Mindstorms software since Bitdefender seems to say that it came from the Internet Explorer.
Is there something wrong with my PC?
Or is this occurring because of the Mindstorms Software itself?
Btw, this happened to me two times in a row.
EDIT TO ADD
It turned out to be some corruption with the Mindstorms software, according to Lego. It didn't remember my brick because I used the Lego site to update firmware to a version that the software didn't recognize. Even now it still tells me to downgrade.
