Bitdefender security keeps uninstalling com.google.android.trichrome library

Hi Members,

Bitdefender Mobile Security does not remove files on its own, it's prompting the user to decide. Can you please upload a screenshot?

Stay safe,

Mike

Hi @Kodhee ,

Thank you for sharing this in the Expert Community. You must've received one the following messages:

 %s app was uninstalled during on install scan.
* {app_name}: %s was uninstalled while the scan was in progress
* Malware Scanner: %s app was uninstalled during on install scan.

The idea behind is this:

1) Bitdefender Mobile Security detected a new event, in this case a new package install/ update, so started scan

2) Until BMS managed to extract info from the package or get a final answer from the server whether the app is clean or not, the system decided to install/ uninstall immediately, before BMS got the verdict on the app.

There are some discussion over the web on this library, not necessary antivirus-related , but rather glitches : https://www.thesharedweb.com/com-google-android-trichromelibrary/

Stay safe,

Mike

Not an expert, but I think I can explain what is happening here a little more clearly:

When Google Play Store upgrades chrome (which includes com.google.android.trichrome) this triggers Bitdefender to do a scan, whilst scanning the upgrade process continues.

The Play Store removes a version of trichrome as part of the upgrade process. Bitdefender sees this package disappear whilst it is still trying to scan it and therefore generates the report that the app was uninstalled during the scan triggered by an "on install" event (which includes upgrades). This message could mean that a virus is trying to hide itself by uninstalling parts when it detects a scan happening, but in this case is more likely harmless as Chrome is upgrading at the same time.

TL;DR Bitdefender is not uninstalling trichrome, rather it is warning that something else uninstalled trichrome whilst Bitdefender was trying to scan it. If Chrome was upgrading at the same time, it is harmless. If Chrome was not upgrading at that time then it could be more serious, hence the alert.

Experiencing the same issue. Keen to hear from the BD team on a resolution for this issue.

I too just started receiving 38 BitDefender trichromelibrary notifications overnight (all by itself) and then 38 more after I manually updated 11 apps through the Play Store.

I got one of these pop-ups. It doesn't match up with the time Chrome was installed. Anyone have any clues as to what is going on?

Alexandru_BD, that might be fine for some people but turning off a warning mechanism seems inappropriate. I've run BD and Chrome for years and these new trichromelibrary notifications are a very recent phenomenom for me. What's changed to induce them? If they are just a nuisance notification then BD should add a management mechanism.

com.google.android.trichromelibrary*

Hi Alexandru,

"Surely you have it on your phone."

I have Webview but not the trichrome library. This is searching all apps in system settings with show system apps on:

Nothing there (I've tried looking through the list and searching the whole string - it's not listed). As per my earlier post it appears to have been uninstalled by BD:

Please advise.

The APK mirror site has three versions released yesterday. None of the version numbers match the one uninstalled. The phone updated overnight while I slept, and I got this notification this morning.

Hi Alexandru - it's not a safe practice to suggest to BD customers they should download apks from a 3rd party website. There is too much unknown risk for this to be a suggestion.

I understand the issue and how it relates to WebView, but this should be raised with the Google/Andriod devs as causing a poor UX for BD customers.

This type of notification which may seem minor is enough to confuse paying customers and raise doubt on your product. Its def not a matter to brush off maybe in the BD APP warn users of this issue or have some mechanism to inform/address the alert.

@Ak47code In case if you don’t want to download the app from a website like APK mirror, there’s still a way to successfully download com.google.android.trichromelibrary by clearing Google Playstore app cache:

1. Go to Settings. 
2. Tap on ”Apps.”
3. Find and open “Google Play Store.”
4. Open ”Storage” and finally, tap on ”Clear cache.” 

In March 2021, after a new update of Android WebView was released, thousands of users started complaining about crashing apps: Gmail, Facebook, and Amazon. Google advised users to update their Android System WebView and Chrome browser to fix the issue. So it's not the first time we encounter issues with this.

As a side note, it might be a good idea to update Android WebView and Chrome (if not already updated):

1. Open Google Play Store app.
2. Search for “Android System WebView” or Chrome.”
3. Tap on the “Update” button.

Going forward, the Mobile Security developers are currently investigating this and we are pursuing the possibility of a fix from our end.

Regards

Deleted PlayStore cache.

Uninstalled WebView updates, reinstalled them.

Still no library. Bitdefender also reported deleting it again last night. I don't get multiple notifications, but now two nights in a row.

Alexandru,

Thank you. I'm a paying customer with almost three years left on my third renewal of a ten licence pack.

Am I going to see a quicker response by raising a ticket please?

I only jumped in here as the issue was related, but it's not multiple notifications, and it only started two days ago.

Thanks @Alexandru_BD 👍

FYI: I have been getting this for a few days as well. Followed the steps this morning. Even uninstalled Android System Webview, updated, got 28(?) immediate notifications.

Long time user, first time poster.

Hi,

The developers are troubleshooting this as we speak. An internal investigation is conducted by our mobile security specialists and with the help of Google, they should be able to fix this soon.

Bear with us for just a little bit longer, I completely understand the frustration and inconvenience this situation has caused.

Thank you everyone for your valuable input during this investigation.

Stay safe

Hello, I am still getting 25 of these messages every night. Cleared cache, what else?

Thanks Alexandru,

I hope this fix will allow it to install, as the answer to "Surely you have it on your phone" is still no in my case. I'm getting one notification nightly when my phone auto-updates.

I got the update. I will find out tonight if this is a good or cosmetic. Another message last night that trichrome library was deleted during install .. once every night now since May 10th.

@Alexandru_BD

Thanks, and yes I will let you know, of course. I think that is part of being a responsible member of the community - and to support when things go right, or not.

Ifi get the message again, or if don't but trichrome library is still not installed on my device, I will disable Bitdefender for one night and see if the library is then installed. This will offer more insight for the team to work with.

Hopefully all good now though 👍

Hi @Ak47code,

Thank you for sharing your feedback with the community, glad to hear this has been resolved. 👍️

Hi @A_Person,

That is good news 😊
