comment Why does Ubuntu 14.04 keep shutting down when playing video?
Seems like the most relevant information and most likely root cause is using a proprietary Nvidia driver (the "tainting kernel" warning). Two options are: 1) Use explicitly supported hardware 2) use a generic video driver (not nvidia binary). I realize this is not ideal/optimal. Personally, I stopped buying Nvidia stuff. Will gladly buy again once they become more Linux friendly.

comment AVAST antivirus for Ubuntu?
Why would you want to run Avast on Linux? What do you think it will give you?

comment AVAST antivirus for Ubuntu?
I would go further than Rinzwind. Installing privileged proprietary binaries on Linux (not just Ubuntu) makes your system less secure, not more. Be very careful with installing anything you can't audit especially when it has to run setuid, intercept system calls, etc.

comment What antivirus programs are available?
Be careful when someone suggests you should download a "free" binary for Linux from non-official repositories. At best this would vastly increase your attack surface. At worst, it'll get infected with malware. Is Avast open-source? (if so please post a link to the source). Can it be audited? Does it do auto-updates? Does it run as root? Does it intercept system calls and modifies their semantics (e.g. can it make a read of what it thinks is a "virus" fail)? Given my take on the answers to the above questions I don't believe it can improve security on an otherwise clean Ubuntu system.

comment What antivirus programs are available?
@EliahKagan - ClamAV is mainly intended as protection by a Linux system to other (non Linux) systems. It is not needed to protect Ubuntu itself from native viruses. I think that yes, this accepted answer should be modified to make this clear. As is, it misleads by suggesting that Linux in general has a virus issue which one needs protection against. Thanks.

It is also misleading. It implies that you actually need AV on Linux to make it more secure which is a fallacy. Note how up-voted answers are suggesting non-free and non open-source "solutions" to a non-existent "problem". Commercial AV solutions would make your Ubuntu system less secure by introducing proprietary privileged code, possibly with auto-updates and "phone-home" mechanisms to your system. By allowing and encouraging such AV systems to be installed, you actually open yourself to who knows what.

comment Do I need to have 'antivirus software' installed?
The need for AV to prevent user-level damage is a complete fallacy and non-sequitur. You can do user level damage like removing $HOME without having a virus. No one can protect you against your own free will to destroy your system, certainly not an AV. The only relevant question is do you willfully download and run untrusted code from untrusted sources. On Ubuntu you can't do this unwillfully.

comment top like utility for network activity/ports by process
Thanks! nethogs seems the closest to what I'm looking for. I wasn't aware of it. Wish it would have displayed a PROTO, PORT and process STARTTIME too. This is especially needed for the unknown TCP entries...

comment Do I need to have 'antivirus software' installed?
Once you start on the slippery slope of installing non open-source software which you can't audit (like bitdefender) from places that are not the official Ubuntu repositories - yes, you might have introduced a security issue to an otherwise pretty secure system.

See this answer: security.stackexchange.com/questions/438/… it makes a pretty strong case for not using AV at all and suggest stronger alternatives to security. Most of these alternatives are standard on Linux.
