If there is no access in the scheduled time zone, execution of auto scaning may be delayed.

Can I switch the screen during scanning?

Scanning will be stopped, but the files are scanned properly and are recorded up to that point. Please restart scanning or wait until auto scaning is completed.

Login captcha is not displayed, or captcha value is not accepted.

Due to using Jetpack single sign-on function or caching plugin together, cached login screen without captcha or login screen including old captcha (captcha is generated at every access to the login screen for security) may be displayed. In this case, please create a URL as follows and try to access.

http://URL of WordPress/Changed login URL?jetpack-sso-show-default-form=1

If you have changed wp-login.php and login URL with a caching plugin, it is recommended not to cache the changed URL.

What if malware is detected?

When a malware is found by scanning only with pattern matching, there is a possibility of misdetection. Please consider waiting until the code is reviewed.
Please note that the website has been tampered when some files are judged as malware as a result of definitive diagnosis of individual files.

● If the malware is infesting the file originally consists WordPress, please delete only the tampered parts carefully.
● If the file is not a regular file of WordPress, the entire file can be deleted without any problem.
