Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning

The worm spreads by sending text messages that contain variable messages in Chinese and a link to a website at 184.108.40.206. If the link is followed, an application will be installed promptly.
The malware will be registered to start on the phone boot up, and tries to connect to a website at http://rec[...]rzwxdsu.com over GPRS or 3G connection, infecting the phone and restarting the SMS spreading.
