Hi,

Since a few weeks, I noticed a strange behavior in Firefox for android : at first when I when I wanted to type in the search box for example "sony", after the letters "s" an "o" were displayed, it opened the site "soamsung.com", and because I enabled URL filter in my antivirus (Dr. Web), I was redirected towards a warning page about "Not recommended websites". The same happened when I typed something beginning by "er": it opened "erbay.com", but this was blocked by URL filter as well. There was other examples like this, I begin to type, then I'm redirected.

So I uninstalled Firefox and reinstalled it. I precise no malware was found in Dr. Web so I tried Malwarebytes : no malware was found either. Later, despite reinstalling, I observed the same behavior, but this time with "to": the towitter.com website opened, but was blocked. So, by curiosity, I looked into the firewall feature of Dr Web (which record all internet connections of each app) and saw something : very late in the night or very very early in the morning (when I don't use Firefox because I'm sleeping), there is connections coming from Firefox to some IPs, different from a day to another. They seem to be located anywhere on the planet (one from Madrid,Spain or another from Oregon USA...) according to whatismyip.com and the ISP is Amazon.com Inc.

How can I solve this ?

Thanks for helping.

Hi @rdell,

It sounds like it could be browser related.  I would try clearing your history and cache in Firefox.  Then also the storage and cache within the App info section of your device (settings>apps).

If that doesn't solve it, we can look for Adware on your device.

Thanks for reaching out,

Nathan

Hi @mbam_mtbr, thanks for answering.

I followed all the steps you mentioned above, but the same pattern repeats : when I type "to" (whithout pressing enter), Firefox tries to access towitter.com and is blocked by URL filter.

How can I look for adware on my device, knowing that neither Malewarebytes nor Dr. Web detect anything ?

Thanks.

Hi @rdell,

I can check for adware if you like.  All you need to do is send me an Apps Report.

To send an Apps Report with Malwarebytes for Android use the following instructions.

1. Open the Malwarebytes for Android app.

2. Tap the Menu icon.

3. Tap Your apps.

4. Tap three lines icon in upper right corner.

5. Tap Send to support

Choose an email app to send Apps Report.

Your email app will open with the Apps Report included.

At this point, it would be very helpful to mention you are submitting via recommendation from the Malwareybtes forum.  This allows our support staff to know where to direct it.

By sending the Apps Report, you will create a ticket in our support system.

Private Message (PM) me the email used and/or the ticket number assigned.

Nathan
