Note: Due to the whitelist policy of Qihoo 360 antivirus software, ETAGEAR has to submit an application to 360 for each new release, and it takes about 24 hours to get the application passed. So every time a new version is released, it may be mistakenly reported as a virus by 360 within 24 hours. However, you don't need to worry. After 24 hours (the day after the release) As long as you update the virus database of your antivirus software and rescan it , it will no longer be reported as a virus.
