    Do you really believe that those were 1400 real trojans? More likely 1399 were sales/marketing hype to get the gullible to bite, give up their credit card data and then the real fun begins.

    Ive been using Windows since 2.0/386, skipped a few dogs, and currently stopped at XP until 7 and 8 go away and 10 becomes the next useable version. Heck I have one PC with just DOS 5.0 and 6.21 loaded as a few programs I use were never upgraded to WIN or anything else.

    Ive been using several AV programs over the years starting with McCrappy, Norton before it got bloated, Kasperzy, Avast, and currently use AVG 2015 Free along with Malwarebytes Free, Spyware Blaster, Spybot S&D (the latest version is a huge improvement, CCleaner.

    With 9 PC's/laptops/Smartphones in the house used by me, my GF, and my youngest son (27) we have set behavior rules as to what and how things get downloaded, updated, etc. My GF is Russian and even a little porn is acceptable if I share it with her......

    I disagree. Linux is not nearly as bulletproof as everyone would like to believe. Security can only be as good as the users.

    If you really want to avoid viruses, disconnect from the internet and remove all mass storage I/O options. Or, run a single-tasking computer with only 64K of available RAM. Or, build your own computer and write your own OS.

    Security by obscurity isn't half as bad as the experts would have you believe, either. You wouldn't believe how many times I watched someone try and hack my Amiga thinking it was *ix or *ux. It was good entertainment.

    LOL.

    Nice Carl. Your GF must be great.

    I agree, a lot of AV software says you have a lot of problems. But provides a Click Here to fix them all.

    After you give a credit card number of course.


    People that click the "Fix your computer Now" and expect a magic fix, should not be on the internet.

    Yep, a real surprise to find her also at my ripe old age; she will be 48 next month!

    Tanya was a Russian Army pilot, props and choppers, for 10 years and got fed up with the sexism and told she didnt have a future for advancement beyond her present Capitan plus the Army was being downsized anyway.
    Then to the St Petersburg Police, mostly Search and Rescue, and some interrogations of the various ethnic groups in the Confederation. She speaks fluent Chechnyan, and several of the -stan languages since all are/were in the Army and taught herself English from movies, TV, and shortwave radio plus visiting VIP's and military cooperation officers she ferried around.

    She has been here for 12 years, a happy US citizen, and still flying and interrogating, now for a US agency. Im slowly learning Russian and flying as she uses me as an excuse to keep her instructors certificate current. I expect her to get a ham license next year and she drives others crazy when I let her talk on AM; the accent is "adorable" as many say and I already know (-; I just have to keep reminding her that she has to watch her tendency to swear/curse a bit when getting animated/excited which has been the norm in her daily life for decades now. As ex USN I still slip at times!

    My #2 son who taught himself Russian years ago as a means to get into the field he wanted, retired from the USAF as a Major, now lives in Germany which he speaks like a native, has a Russian GF and its a blast when we all get together on Skype...and they enjoy picking on my pronunciations while helping the learning process.

    Specifically Linux distinguishes between kernel and user runlevel, memory and data. User processes are in fact, run on behalf of the user and contained in terms of the resources they may access. Windows does not hold such conventions, and as such, often programs running under a API may directly touch the disk, display, I/O ports, etc. When user programs under Linux attempt such nonsense, Linux simply shuts them OFF - terminates their main and subordinate child processes. reporting an error in syslog. All I/O calls must go thru the kernel, hence no chance of any funny business, including but not limited to: wholesale file access, calls to root-only utilities, access to system processes, the ethernet port, tcp-ip stack, system daemons, etc. Malware relies on Windows "ignorant-by-design" approach to networking in order to take over your machine. Linux being based on UNIX has the superior security designed in knowing full well that every user program is suspect in terms of security. HENCE, Linux does not need a "virus scanner", registry cleaner, malware scanner, etc. It's all built in. And remember: Linux is FREE! ;)

    Really ?

    Not really, Windows systems use Ring protection.

    Most Viruses run in Ring 3. That is all it takes to Hose the system.

    Some viruses may have access to Ring 1 or 2 if you have a rouge driver.

    Getting to Ring 0 may be a bit harder, but can be done, even on a Unix box, If a user really wants / needs to. I am sure you have been there done that. I have, but only for embedded programming normally.

    The problem with Windows is that people go click crazy, Even when it asks "Are You Sure"

    And they run automatic updates, because they think they are needed, when they are not.

    I would suggest that your success with not getting malware has a lot more to do with your good surfing habits and general computer use knowledge than using Linux or OSX. Both those operating systems are just as susceptible to any machine-independent mobile code as Windows (i.e. Java, Java Script, Adobe Flash vulnerabilities, Chrome and Firefox vulnerabilities, etc.), and both have their own hacks.

    The only reason you don't see and hear more about Linux and OSX being trashed is that they're small market... Linux and OSX people *think* they're safe, but nothing could be further from the truth.

    Linux was certainly not "designed for the internet." it was designed to be a UNIX knock-off that regular people could use. It pre-dates the bulk of what we now call the internet by many years.

    FWIW, I just got hit with a Trojan on eHam. Fortunately MalwareBytes prevented it from communicating until Norton killed it. Two ip addresses in Mother Russia and one in Jolly olde England.

    Just a couple of things, you can still run your favourite Windows flavour as a host in Linux via VirtualBox. I have Windows XP installed just for one reason, and that is to run the software for updating my satnav, this is the only reason I've got it on there, otherwise I would kick Windows into touch.

    Anyone looking for a decent flight simulator for Linux have a look at Xplane it runs on both Linux and Windows, you will need a hefty video card to run it to get the best out of it though.

    I have done the same. Have you tried Win8 via VirtualBox ?


    Have Fun.

    I had enough trouble using Windows 8 in its normal environment, certainly wouldn't want that infestation on my machine thanks.

    @OIJ I would suggest those using Linux are savvy enough not to fall for a "banana in the tailpipe." ;)
