I'm using Bitdefender as an antivirus software, but there has been one file that scares me so much in the Quarantined section of Bitdefender. This certain file named m.lnk can't seem to be deleted. I tried deleting it in Bitdefender and finding the file manually. It never disappeared. Recently, I'm having problems with my PC wherein sometimes it suddenly changes to Windows 7 Basic theme and some of my files seemed to have corrupted. I'm a bit paranoid that this file is causing all these troubles that have been happening. Can anyone help me about this one? I also can't see information online about this certain file.
