I am using Comodo Ice dragon browser on my Vaio laptop. I know I haven't downloaded any updates. However, just today 3/3/20, I open up my laptop as usual, when I opened up the Comodo Ice dragon browser, a message popped up stating: "History and Bookmark system will not be functional because one of Ice dragon's files is being used by another application. Some security software can cause this problem". I don't know what to do to retrieve back the history and bookmarks. I haven't backup on any of them. I only backup what was on my desktop. This is the first time I encountered this problem. Also I searched for solutions online, however it keeps going back to the same solution but for the Firefox browser. I need answers as to how to resolve this problem.
