I actually don't agree with this at all. I'm tempted to remove the post, but I'll let it stand for now; in the future, be sure to remember to include a link to the source.
Viruses can and do write entries to the registry that will cause them to respawn even after a heuristic scan by virtually any a/v application out there. This is what is so misleading about the article. You can get hit with vundo, and if you fail to remove the source cause, it will simply keep respawning itself, no matter how many times you remove it.
Other a/v programs fail to even pick up certain viruses. A good test for your a/v is called the
Eicar Test; save it as a text file and see if your a/v picks it up.
The bottom line, IMO, is that in many instances neither malware nor viruses can be removed 'easily'. One can do a LOT of damage to one's machine attempting to run some of the fixes out there, and there are just as many rogue antispyware programs as there are viable ones.
As far as taking it to a professional (which, indeed, can be quite costly) we here at PCHF have a fully functional virus removal section at
Security & Safety - PC Help Forum - Free Computer Help, Windows, Hardware, Software and more!. I have sent dozens of people here to get there machines fixed for
free (donations are always accepted

), and furthermore, as I work in the IT industry, I can state that companies such as Circuit City and Best Buy are not necessarily looked on with high esteem in their viral removal capabilities.
There is a reason that it takes a year or so to graduate from Malware Removal University; it's a tough course, and it's a tough field.
Not meaning to sound harsh here or anything, but I think that you are vastly underestimating the pervasiveness of viral infections in the wild today.
looking forward to your feedback, actually.
thanks,
