There youve done it now..you touched a nerve.
Why do you boldly proclaim Linux to be the produce of an arse?
I,ve been using it for about 8 years,no anti-virus protection and I haven't been bitten once!
It does have some failings I agree,but less so than Windows. Biggest gripe is on the hardware side because Microsoft stitched things up with the manufacturers--wouldnt be nice if Vauxhall made it so that their cars only ran on Dunlop tyres because the wheels were square and welded on.
Penguins forever,Linux users unite and let us be Revolting. 
Too be more serious, anyone wants to try Linux then I heartily reccomend Mint.

That is a common misconception about Linux or any other non-MS OS. Virii exist for all common OSes.
The advantages *nix have is they strongly encourage you to never run as superuser, thus (OS flaws aside) anything you run in theory cannot cause OS issues. Microsoft have been pushing the same idea since the release of NT back in 92, but once 9x and NT lines merged with XP, many home users consider it a slur on their penile size to run as anything but Administrator. Hence the UAC built into Vista and later to overcome this.
Running without AV is an appallingly bad thing to do, and I strongly urge you to install some protection.
Now I work as a 3rd line support techie with several flavours of Unix (and Windows), each with its advantages and disadvantages. Linux advantages are quick development cycle, and it runs on cheap hardware. Disadvanatges are poor resource management and reliability. In the server arena, cost is another disadvantage. Linux's biggest advantage, and to be honest probably its saviour, is it will run reasonably well as a virtual server under the 2 most popular enterprise virtualisation systems - VMWare's ESX and Microsoft's Hyper-V
Linux has it's place (somewhere!), but its sure as hell not on a general purpose desktop. Or on most servers. It has carved out a nice niche for itself on web hosting servers due to low cost hardware, and the power of the Apache web server software.
