Avast Antivirus

Post by jeff37922 »

Do I need any kind of antivirus program on Linux? Or are viruses mainly a problem for Windows users? If I need one, would Avast work on Linux, or is there something else that's better?

No need for an anti-virus program on Linux at all.

don't fall for those scams.

for windows, yeah, it needs a helping hand.

a lot of folks do like to use CCleaner, but they generally don't know,
that piraform.com which is it's owner - was bought out by Avast, the A/V company.
- as piraform.com has a add-on product, which is part of it's A/V suite that competes directly with CCleaner.

but - that's on the Windows System, and thus is not relevant to your LinuxMint System.
ie: you don't need any A/V on your LinuxMint System.

What strikes me as odd is that there is linux malware out there yet not many, if any, of the regulars are actually concerned by it.

Hi jeff37922,

I just read your post and the good replies to it. Here are my thoughts on this as well.

Linux Mint users do not need an anti-virus application installed and it is not recommended although you can.

Previous post
Need for an antivirus.? - Linux Mint Forums
viewtopic.php?f=90&t=238726&hilit=maldet

I do not think Avast offers a current free version for home users, but they seem to have a paid for version for businesses.

Hope this helps ...

as a General Rule - - you don't need any A/V on your Linux System.

but that Malware is something else - - it often is Browser Based, rather than Operating System Based,
and it can affect your Linux System's Web Browser & so you could us a Malware Blocker in your Browser.

then again, it's not something that I'm doing on any of my PCs,
as I've figured that the attack can't do too much damage, unlike what could be done to any M$ based system.

One of our members, Pjotr, has a great Linux website, and one of his articles is about why you don't need an antivirus in Linux, and in fact may expose your computer to greater risk by installing one.

Hi, on the topic of Antivirus, if I am using VMware on my Linux Mint PC and running a virtual Windows PC which has Internet access through the host Linux PC, is it possible that this could cause an virus/malware issue on the host Linux Mint box??????

@wassa350:
What happens inside a virtual machine, stays within the confines of the virtual machine. Since you browse the web using whatever browser you use in the Windows guest, any infection only affects the guest. Also, as long as the host machine's directories are not exposed to the VM, you should be fine. And even though you shared a directory between the host and the VM, chances are there is no significant effect on the host since the malware only targeted your Windows guest. Say, you downloaded some random EXE, MSI, what-have-you Windows executable to the shared directory. The file will run under Windows but won't get that far in the host. Linux doesn't know how to interpret machine code designed to run on Windows, unless of course, you have WINE installed on the host or the shared directory is used by an application on the host that is capable of interpreting and executing machine code in that shared directory.

It goes without saying, apply contemporary and best security practices with a healthy serving of common sense and you should be okay.

Say, you downloaded some random EXE...
... so, apart from really, really bad websites, it usually takes a (user) interaction.
Unfortunately, mouse clicks and common sense rarely interact with each other.

Well I , for one , am concerned about it , and I keep a constant weather-eye on the situation .

Most of what I see is either of the proof-of-concept variety ,and I can't find any well-documented real-world infections ,
OR malware aimed at Linux servers ( ie. the majority of servers ) but designed to infect MS users ( one of the few sensible uses of ClamAV etc.)
Of course , the very nature of GNU/Linux systems makes it much more difficult for malware to actually do anything useful/destructive ,
compared to the almost limitless potential for causing havoc on Windows systems ( eg. via Registry changes and privilege escalation ) .

But nasty stuff targeting LInux is definitely out there , no mistake about that .
Example : credential-less command execution

Here's a very recent report :-
https://threatpost.com/local-privilege- ... ss/137748/

And remote privilege escalation on Linux has been successfully demonstrated in earlier cases :-
Hmm - on second thoughts , maybe shouldn't post that link ( send a pm if interested ) .

But I will maintain my " watching brief " and I trust that you and others will be doing the same 8)

PS - none of this makes a convincing case for GNU/Linux needing an AV , IMO .

Yep , that one is interesting / troubling , and certainly goes beyond proof-of-concept
I hadn't seen it before , thanks for posting !

And I note that your quote included the qualifying remarks I made , and I respect that .
We are in agreement that this stuff is "out there" , and needs watching :)

Until now most Linux machines have been quite immune to attacks , but as Linux rises in popularity, It will be attacked if for no other reason than it will be a Challenge to the writer of malware. So we need to be diligent and not bury our collective heads in the sand. Keep current with updates and use good personal computer practice by not visiting sites that are known problems , some free gaming sites are quite bad in this respect. But most A/V software is not really useful on linux. At least that has been my experience. The article that's been cited above is a good one https://sites.google.com/site/easylinux ... t/security
This page is one that ranks some web sites as particularly dangerous https://www.makeuseof.com/tag/websites- ... t-malware/ again this is mostly a MS problem, but still bears watching.

and the pages catweazel posted also bear watching, for now be careful and enjoy your linux freedom :)

So that's a forum for hackers and other users of a subversive, underground, noncommercial-so-probably-illegal operating system, and a forum for bikers (no further explanation needed). :shock: *shiver*

so what makes you think that?
it is legal software, and hosted by the largest motorcycle forum host in the world.

oh, you meant this forum, oh, ok.....

and you use the term 'bikers' negatively? for shame....

Sorry, it was a feeble attempt at a joke... as you probably know by now, I'm a biker myself.
And I use the term 'hacker' positively in daily life because most of my friends are hackers (no, they're not computer criminals).

that okay,no problem at all, I think you just used the wrong emoticon, as that is what I keyed on.

My yellow bike, and I took a ride today, met up with a friend about an hour away, and then we went another 1.25 hours on to Ponca City, Oklahoma to enjoy some good food at Enrique's Mexican Restaurant. it is definitely a 5 start family owned and operated enterprise. will go back some day.

here is my SPOT tracker map

it can be moved around, zoomed in, convert to Satellite view and see where we ate at the airport, upper left corner is where the restaurant is.
