    In my opinion, the fear of viruses is far greater than the threat. Taking myself as an example, I do not practise what is usually referred to as "safe browsing." I am not afraid to "accidentally" visit dangerous places like porn sites and download something, (I know. My bad.) and I have never had a virus. The main key to avoiding them is using a little common sense. What is my definition of safe browsing? One example; if an e-mail is received from an unknown source and includes an attachment, open the attachment at one's own risk. And of course, web sites offering something too good to be true are too dangerous for even me to venture into.


    Not yet. Wait a couple more years.

    This article misses the entire point of AV software for GNU/Linux - it's primarily targeted towards mail servers or file servers which serve windows based networks.

    What do you mean? Are you saying that Linux anti-virus software is intended for Linux servers on Windows networks?

    The Anti-virus software scans the files that Windows clients upload/download, helping to prevent spreading. I have Anti-virus on my server for this reason. A quick scan weekly on the "server shared files" helps to fight windows-based viruses. Sure the Linux Anti-virus software also fights Linux viruses, but it is more effective at keeping the Windows clients the server "serves" safer.

    Although very brief, those are still two of the most informative posts I have seen on the web concerning virus protection.:cool:

    The tech press are in the news business, which is tantamount to being in the ad business - the world likes bad news - it "sells papers".

    I've skimmed a lot of articles about "Linux malware" over the years and none have ever been worth the read... you usually get to the end and read something like 'it only affects Linux 2.4 and only if the user is running everything as root'...

    I'll give you an example - I did a search for "new linux worm":

    http://www.linuxtoday.com/security/beware-of-new-worm-targeting-linux-pcs.html
    (several were clones of this)

    Then

    http://arstechnica.com/security/201...s-routers-cameras-internet-of-things-devices/
    It's important not to be naive here and understand what is going on. Firstly the main target here will be Linux based devices (cisco, netgear or whatever routers, etc) running horrendously out of date kernels.

    There will be a rush of people to buy new domestic wifi router/modem boxes - symantec often bundles it's software with new routers...

    The articles appear to put the blame on open source software and Linux and of course it's symantec, a leader in the "virus industry" who depend on the proliferation of malware in order to sell their subscription shitware...

    The blame in fact lies squarely with the companies who produce these devices, who fail miserably in providing up to date firmware and give no assistance whatsoever to those trying to produce open firmware to replace the aging one. This is despite these companies using Linux on their devices and profiting from it.

    I had an interesting problem: mama gave me her USB Flash to copy some files, after copying she found some viruses on the device, so here's the question: if I got a virus, maybe it was written only for Microsoft Windows or I need to find an additional security?

    If the virus is for Windows then it will not effect Linux. But for the sake of security, wiping it with a program like Gparted may be a good idea.

    I usually install AVG to scan windows and just wanted to give an update to the avg URL it is "Not cool enough to post links yet". The URL above "still not cool enough to post links" currently goes to a windows only download.

    Thank you for the article! Much enjoyed!
