Of course, if you don’t know the fact that it’s no an Android malware you might be scared that your device is infected. After all, the fake pop-up claims that your SIM card may be infected and you will soon lose your contacts and other important date. Scary, isn’t it? but down’t worry.

If you got this “Malicious viruses: Rootkit.Sirefef.Spy and Trojan.FakeAV-Download” pop-up once and you managed to close it then you are probably fine.

If it does you will also lose your history, bookmarks etc. but that’s the price you’ll have to pay. If the clear operation doesn’t work you may need to do a factory reset, but back up your important data first.
