Why is my back up aborting with a code of 0x810000037?

Aborted Backup

I did a little bit of research on this and I'm including a link with this transcript to an answer out on Microsoft.com.

The theory is that of all things - it's malware.

• See: The system cannot find the file specified. (0x80070002).

The answer that's out there seems to indicate that a particular form of java-based malware can cause exactly this behavior. Make sure that Microsoft Security Essentials is up-to-date and up to the latest, then you can resolve the problem.

It will find malware that's on your machine, remove it and after doing so, the backup will complete.

Keep virus software up-to-date

My recommendation, in general, for most of these kinds of solutions (of course!) is to always make sure you are running up-to-date anti-malware software. Make sure that you're running it regularly and you're running anti-malware software that is recognized as good (and recommended by others.)

I have my own page of recommendations of which Microsoft Security Essentials is currently top on my list.

• See: What Security Software do you recommend?

It's just one of those things that whenever you encounter an unexpected problem like this, it's worth making sure that all of those boxes are checked; that all of these things are being done:

• That you are running anti-virus software.
• You're running anti-spyware software.
• You're behind a firewall.
• That all the software that you're doing this with is as up-to-date as possible.

So, give that a try. Chances are removing some malware will simply take care of the problem for you.
