Possible Anti-Virus Software Issue / AVG Free 8.5.285

Good evening! I am not sure I have an issue or not but I have never had an anti virus scan return such a thing and the list has grown over the past week. I am currently running Microsoft XP Home Media Center and I am not exactly sure which files have added themselves as locked over the specified time.

I recently downloaded HijackThis but as that forum seems to be jammed I didn't want to add to the workload there. What should I do to look into this matter? I have done the following already:

1. Scanned with Kapersky - Trojan found in Outlook Express deleted items - cleared those and now clean
2. Attempted TrendMicro's Housecall without success - wouldn't run on my machine although it HAS in the past
3. Ran Malwarebyes and Windows Defender with no infections showing

Am I paranoid? What other information can I provide to make that determination?

Thank you guys very much in advance for any help. You all do an amazing thing here!

Hello. these are normal findings in scans. They are skipped files. When the scanner runs it comes across these Operating System files and they are not allowed "locked" by the system to be scanned. It is a way of the system protecting important files from being accessed by what may be a dangerous device.
If you still feel a little paranoia feel free to post that section of the AVG scan that showed them.
