What if the downloaded weather forecast APP seems to be virus software?

Delete it, as long as there is a little sign, it should be deleted, otherwise it is really a virus, and you can't cry, or your next Tencent mobile phone housekeeper can have a look, he can identify virus software. You can try to see if it is real virus software. If not, keep it, if there is, use it to force uninstall. The Chinese New Year is coming, so be careful, or you will ruin your mood in vain.
