File Help :X

I was looking through the files on my hard drive (sweeping through) and i found out I fo sho have a virus :( (Due to me not having "access" to delete it even though I am admin and have all admin privaliges, plus the file name is like f50067238047abc bla bla bla with all these random files in it). My anti-virus software literally expired 3 days ago too ><.

Either way, the main point is, I NEED HELP!! How do I remove this file that I can't delete since I don't have administrator permission to do (even though I am the admin..)

I already tried some methods derived from Google but none have worked :(
