So today I was browsing in my pc and I found that that in local disk C: there is a text document named : "csb" , when I openned it it says "finish!! " .
I scanned my pc and that document but no virus was found, it was created 15 days ago, not sure what it could be, can't find information anywhere. I run windows 8.1, antivirus and ccleaner, everything is updated. My other computer doesnt have this text document.
I thank any information.
