Cant delete files on E: Can you help?

Hello,

I recently installed Nortons and had to remove McAfee. Everything came back clean. Not sure if I did something incorrectly but I now have an E drive that is filled with files that appear as the following. My original files are there and have no problems.
$√???▌.╗░▒

`?⌐???+.?▄

There's 100s of them. I tried deleing but I get an erro that says: CANNOT DELETE FILE: CANNOT READ FROM THE SOURCE

I tried opening and it says: the file name, directory name, or volume label syntax is incorrect

The properties show 0 bytes but the drive shows like 3,000,000 kb for most of them.

I'm very unsavy when comes to internal computer problems. Please help if you can.

Thanks
Ben
