Locked out of Docs & Settings/Owner folder in XP Pro

Hello,
I have recently been infected with both CWS and JS Byte.Verify exploit. Something (One or the other of these two, apparantly) was sucking down my RAM quickly whenever I logged online, among other things.

I seem to have gotten CWS taken care of with the CWS Shredder, and RAM is fine now, but I still have in issue with Byte.Verify. I installed XP Pro (was using XP Home before), and I am locked out of Docs & Settings/Owner subfolders. I can open Owner, but can not open, delete or manipulate anything inside it ("Access is denied"). AVG scanner found two archived files in this folder from Byte.Verify a couple weeks ago (they do not show up in scans since then). None of my other virus scanners list a problem. Re-installing XP Pro doesn't help, that locked folder is still there.
Could someone tell me what causes this and how to correct it? Thanks!
