Windows defender scanned my computer and found a high/severe threat C2 Lop
but is unable to remove or quaranteen the item. It told me error OX 80501001.
I have the latest updates and am running XP.

This error will occur if a threat is detected inside of a container such as a
ZIP file, RAR archive, etc.

The "remove" action cannot (in most cases) be applied to an object inside of
such containers, without deleting the entire container.

The issue is that you may have a ZIP file with tons of non-malicious file
in it, but one or more "bad" files as well that are detected.

For now you can check if the ZIP file has anything else inside of it that
you want to keep. If not, just delete the ZIP file yourself and you will have
removed the threat.

If you really want to keep the ZIP file around but do not want to see this
error gain, you can disable scanning inside archives. Clear the checkbox for
"Scan inside archives" in the Tools section under the Options menu.
Generally, threats inside archives, while good to know about, are not
"active", meaning they can't do anything bad to your system while inside the
archive.

Open Disk Cleanup via Start, Programs, Accessories, System Tººls.
It will scan the system first. Click the More Options tªb.
Now click the Clean up button under System Restºre.
This will remove all but the most recent restore pºint.

I hope this post is helpful.

Let us know how it works ºut.

Engel's information is correct.

Am I right that this finding was on a full scan, rather than a quickscan?

If you filter the System events log on source "windefend", you can find the
log messages recording the original detection at the time of the scan.
Those log messages will include the complete path and filename involved, and
you can decide whether or not to simply delete this file from your system.

Microsoft doesn't do this automatically, because such an archive might
include uninfected files that are important to the user.
