What if the software maliciously orders some monthly services? After I bought a software, I kept refreshing it when I opened it, and then China Mobile sent me a text message saying that I ordered it.

If the mobile phone is infected with a virus, it will automatically deduct the fee, and automatically surf the Internet or make a phone call. You can log in to /b2UNza to search for "Antivirus Pioneer", download and install the free software "Antivirus Pioneer", then update it to the latest virus database, and then carry out malware killing.
