Is this normal so much? Do not have a virus?

Actually, that list looks completely innocent to me. A lot of things are very-routinely going on "behind the scenes" all the time.

netstat is usually used to find a certain type of connection, like listening ports. It's tedious to examine the raw output of netstat without any switches.

See where it says STREAM? That's normal communication within the kernel and the kernel and the rest of the system.

Code:
Active UNIX domain sockets
Address          Type   Recv-Q Send-Q            Inode             Conn             Refs          Nextref Addr
fffff8001c9afd20 stream      0      0                0 fffff80006886960                0                0 /tmp/dbus-tnk2lMbydv
fffff80006886960 stream      0      0                0 fffff8001c9afd20                0                0
fffff800cb25c0f0 stream      0      0                0 fffff80006892960                0                0
fffff80006885d20 stream      0      0                0 fffff80006893d20                0                0 /tmp/.X11-unix/X0
What is STREAMS?


It's the output of TCP and UDP data you want to pay attention to.

Code:
$ netstat -a
Active Internet connections (including servers)
The stream output came from the same command on my FreeBSD box.

It is normal enough. Don't forget that in Unix philosophy all are but files. To implement this philosophy it was necessary to employ "files" through which other functions/users/applications can access but within permissible security protocols. These they call "sockets". Therefore, don't worry about those "stream connection" reports; they are happening only within the kernel space and in some limited incidents in the userland but are not harmful as long as you observe the basic security and safety rules in marshaling your system.

As to your question about "virus". It is less likely to happen in Unix or Linux for many reasons, as this question has already been thoroughly discussed among the matured opinions elsewhere in the internet. But these basic principles should be enough to keep safe:
--Obtain the Installation ISO or DVD/CD only from qualified or safe sources
--Install only applications you understand and know the credibility of the source
--Run the browser ONLY as a $USER not as root
Hope that helps.

m.m.

Specifically, run as a user which is not capable of becoming root ... which, unfortunately, is usually not the case by default.

Your user should not be a member of the wheel group, which is capable of becoming root by entering the command, sudo su and specifying his own(!) password.

This is the so-called principle of least privilege, which leverages the fact that computers are very good at saying "No!" but really don't know when it's right to say "Yes." Your ordinary everyday user-id ... or, user-ids ... should be compartmentalized from one another and have no capability to gain elevated privileges of any sort.

Use multiple user-ids in the same way that companies use separate, lockable, offices and filing-cabinets within those offices for the various people who are doing various sensitive things. And for the same purpose. If you "wear different hats," create a user-id for each hat. Simply by making it "less than trivially easy, or possible," to poke one's nose where one's nose does not belong, you vastly improve the security of your setup, because nearly all intrusions are simply crimes of blind opportunity. If the pizza-box cat burglar encounters a locked front door, he'll simply go on to the next house.

I can't say if it is normal or not just yet. Run wireshark and maybe some other tools to diag network or virus issues.

"Best practices" are tasks that you can learn and use that protect your system.

Ohh, good combintation of netstat without the "n" on the end is not quite friendly anymore. LOL.
