My son just got a nasty malware to his computer even though it has MSE updated and running. Didn't do diddly against the attack. His floorball teammate sent him a download link to download minecraft. The link installed a 'download manager' which hijacked the browser and did probably other nasty things too judging from the spur of network activity, which I didn't investigate any further before restoring the computer from a freshly installed image.
So there it was, MSE happily chugging along and updated and the computer was fully pwned by malware. That's how much you can trust the 'security' products, folks.
He couldn't just visit minecraft.net?
An associate of mine, who's name I won't disclose, is a hacker. He says that the two easiest security programs to bypass in order are Mcafee, and MSE. Not because they are bad, but because so many people use them that it's become the equivalent of riding a bike.
No security software is ever perfect, even the government gets hacked from time to time. It's something that most people seem to be incapable of wrapping their heads around. My brother criticizes me for only playing the same 3 games, and visiting a small handful of websites on the computer. In one afternoon, he visited 56 different websites, downloaded 1.5GB of data and 7 games (their file sizes are included in the 1.5GB of data). The very next morning I got on the computer before work and it alerted me that there were 1 new virus and 5 malware. He promptly tried to say that it was me who caused the problem, so I promptly deleted everything that he had downloaded, including the $30 he spent on games.
As for what gyrene81 said; I am the only one in the house who can fix the computer, except for a few problems that are beyond anyones experience. The problem is that I'm usually working odd hours so I'm not always home to take care of the problem. It's easier on my part to have someone else fix it for $75 than to spend 20 minutes a day for 6 weeks trying to fix it myself. Besides most of the viruses that get onto the computer are benign and cause no noticeable performance issues. There is no security risk because I never do anything risky on the computer. I don't check my bank account, and the online shopping is done with PayPal and green dot.
And also, microcrap is the most popular OS out there, I doubt that will change anytime soon.
