My most recent AVG scan on my Android found a suspicious text message that it said could potentially be part of a phishing scheme. It wouldn't say which message it was, however, it only offered to mark it with a warning (presumably if the message was resent?). I looked through my text messages and there wasn't anything out of the ordinary. Most of them are from people I know and google's system for two-step verification. I did recently sign-up for banking alerts on my phone, and the activation texts were still in my message list. I deleted all of those messages, restarted the phone and ran the scan again - it found nothing. The AVG people I called said it was probably clean, but couldn't elaborate on whether it was a true "false positive" or not. Has anyone had any experience with mobile alerts being mistakenly marked as spam or suspicious?
I would like to inform you that currently these types of sms/texts will be marked as "Suspicious" - as they do contain suspect phrases such as "credit" and a phone number - and that we are currently working on improving the detection engines.
It is possible to add sender to the trusted list. To do so please open AVG AntiVirus -> Privacy -> Call and Message Blocker -> Messages -> select incorrectly marked message -> Add sender to trusted list -> Ok.
Note that the version 3.1 was released recently and its installation is strongly recommended.
