The file in question "40157" is a zip file, if I run clamscan manually on the file it works fine:

----------- SCAN SUMMARY -----------
Known viruses: 4508245
Engine version: 0.99.2
Scanned directories: 0
Scanned files: 1
Infected files: 0
Data scanned: 11.87 MB
Data read: 5.84 MB (ratio 2.03:1)
Time: 19.107 sec (0 m 19 s)

If I delete the file in question from nextcloud, then on the next cron run it hits the next zip file with the same error message (obviously with a different file id though).

[hunter-nl]

I have the same issue. But the file(s) are not zip files. It is just random files. When error occurs it is always the same file. When that file has been deleted, the on next random file the error occurs.
Only difference with the above system description above is I upgraded from owncloud 8.0.2 and web server is nginx and php5.5.

[schiessle]

This only happens if the anti virus app is enabled, right? In this case it might be a good idea to open a issue in the anti virus repository https://github.com/owncloud/files_antivirus

Did you checked if there already exists a similar issue?

[hunter-nl]

When enabled in owncloud, there is no issue. It only happens when enabled in nextcloud.

[tgurr]

Same for me, I didn't spot this error while running ownCloud (9.0.2).

[schiessle]

When enabled in owncloud, there is no issue. It only happens when enabled in nextcloud.

Thanks, good to know. @LukasReschke is it possible that this is somehow related to your security improvements in Nextcloud? Just guessing.

[hunter-nl]

After upgrading to 9.0.51 or 9.0.52. This issue has been solved for me.

[tgurr]

I still see the error after uprading to 9.0.52.

[chef2gare]

for gentoo like distrib, you should include the patch from kaindl/owncloud-core@1395652
file .webapp-nextcloud-version is used by the webapp manager of gentoo.

[MorrisJobke]

I can't reproduce this anymore with the latest version of the antivirus app from http://github.com/nextcloud/files_antivirus/ and Nextcloud 11.

Please recheck with a newer version if this is still a problem for you.
