Virus intrusion
I use Linux Mint Cinnamon 18.3 64-bit. I installed Firefox 57 via Linux Mint repository. Yesterday I scanned my HDD by BitDefender for linux and found virus infection on my Firefox files. It could be a virus intrusion on Mozilla or Mint server. How to report this?

Re: Virus intrusion
I'm running Firefox also, and I doubt seriously there is a bug in it....
might be, but I'm not too concerned.
I looked at that program, and they want money for it

Re: Virus intrusion
You'll need to post what it found so others can work out if it's real or just a false positive.
Re: Virus intrusion
I wouldn't report anything until you're very sure you are not getting false positives. It happens a lot. It certainly happens more often than real infections happen; if you had one, you'd be the first I've ever heard about. Why don't you post the results, then people in the know can take a look at them.
BTW, as far as I know, Firefox in the repos is at version 58.0.2 not 57.

If your issue is solved, kindly indicate that by editing the first post in the topic, and adding [SOLVED] to the title. Thanks!

Re: Virus intrusion
this is the latest
Re: Virus intrusion
Many thanks for the responses. This is my first finding a "malware suspected" on linux as I used it for 3 years, so I got a little surprised. I dont have such capabilities to investigate apps, but I will recheck by clamav and write the results or log in several days.
Re: Virus intrusion
If you don't know how the application works, what is the benefit you hope to get from using it? I'm not being mean, I'm genuinely interested.
Instead of starting up yet another unneccesary antivirus, post the results from Bitdefender please.

Re: Virus intrusion
Strange. FF is installed by default. So what did you actually do?
Re: Virus intrusion
By quoting the exact message(s) and file names.
Please edit your original post title to include [SOLVED] if/when it is solved!
Your data and OS are backed up....right?

Hi teguh_broadway, & Everyone Else,
I just read your post and the good replies to it. Here are my thoughts on this as well.
I too would like to see the report from your BitDefender's scan, and or printscreens of it.
I also installed and ran BitDefender 7.7 on my system, see results below. It did not find anything in the Firefox 58, or anywhere else, except believe it or not, it did find one in the QT development sample files, a mp4 video file which I had it delete it.
Most Linux users already know that it is not recommended to install an anti-virus or anti-malware package into your Linux Mint system, see link below, because you do not need it. Most viruses and malware cannot hurt a Linux system and they have been specifically designed for MS Windows and or Mac systems with a couple very rare exceptions. Using a sandboxing application like "Firejail" with all applications accessing the Internet will also help protect your system.

There are many posts on this anti-virus topic in this forum already.
But I would like to express my viewpoints on this. There are various anti-virus and anti-malware software packages, some that a user can install are "real time" and always running and others are "run on demand" scanners. The "real time and always running" software packages can pose a threat because they are actively targeted by virus and malware creators and they usually have super user (root) privileges which bypasses the superb Linux built-in security. Most anti-virus and anti-malware scanners are not installed as a service that runs all the time, and do not scan the system's root area unless the user gives it permission to do so, so they do not pose a threat to install and use them like the others would.
Do you really need an antivirus (includes anti-malware) software installed in your Linux Mint system? The answer is usually no, unless you are actively exchanging files which includes music, images and photos, videos and movies, documents, etc... from or with MS Windows or Mac users, and or you download Torrents or other files from the Internet.
And even if you do receive or transfer files with MS Windows and or Mac users there are other options for scanning your files and folders, there are online anti-virus scanners like the excellent "VirusTotal", etc..., and there are excellent bootable versions of reputable anti-virus developer's rescue disks for CD/DVD discs and or USB sticks, like Kaspersky, Avira, Dr.Web, etc... Not sure if BitDefender has a bootable rescue disk for Linux with a nice desktop interface, which can be used to scan files or your whole system?
For those who do install an anti-virus package, I would also caution against automatically deleting or quarantining file(s), check any results yourself, or you could end up removing necessary system files and or software files rendering your system unbootable or certain software unusable. I say this from personal experience. As was already mentioned, another thing to consider is that these antivirus software can and do report false positives which means that some of the file(s) are not really infected with viruses or malware. If you are unsure what the results mean, ask here, or search the Internet.
"BitDefender" is a reputable and reliable anti-virus vendor. What I like about this is that it does not install a "real time" always running service, I can run it on demand or in the background when I want to, and it is an anti-virus anti-malware scanner that works well and fast. I have almost 2 million files and folders in my "Home" folder (much more than the average user) which only took around two hours to run on my ancient under-powered computer.
FYI: I usually run a bootable anti-virus disc (Kaspersky, Avira, etc..) or USB stick to scan my system and any attached drives like USB drives or USB sticks overnight, if I think or feel the need to; I usually run it once a month or more anyway. I do have ClamAV with LMD (Linux Malware Detect) installed for scanning my "/Downloads" folder while still in Linux Mint; turn off PUA in ClamAV and enable scanning larger files. Now I can use BitDefender as well while still in Linux Mint.
"BitDefender" kindly does offer a free Linux scanner version for personal use for now which you have to request a free license for and they'll email your activation key code and a link to download their software. They do want you to buy their business product, and claim this version is at "end of life". I just did this and I downloaded their free file "BitDefender-Antivirus-Scanner-7.7-1-linux-amd64.deb.run" for 64-bit computers, and I think "BitDefender-Antivirus-Scanner-7.7-1-linux-i586.deb.run" is for 32-bit computers.

I think this is for 32-bit computers
Hope this helps ...
In the first Image below, the first file shown in the results is an ant-virus test file that I purposely downloaded to test anti-virus software, the second file is a real file, a video file, that apparently did have a virus or malware issue.
The status box towards the bottom of the results screen just shows files that could not be accessed because they were in use and are not a threat.
This screenshot image shows the files that the scan found to be bad and infected with a virus or malware.
