I am running Mcafee Anti virus 8.7. In my C drive there is a folder called Quarantine & into Quarantine folder there is lots of files with an extention .bup. Almost 500 around. Can I delete all those files? If I delete all those files would it be problem to run OS or any other programs? Even on Mcafee action it says to clean & delete files if its infected. Why still file sore in Quanrantine folder with ext .bup files. Please check my attachment file for action option.
