Please did virus really attaks hardware? And what can I do to avoid this threat
virus' attack data, not hardware. Certainly, though, you need to be running a good AntiVirus application. See here.
The closest I've seen is that joke virus that opened your CDROM drawer. Otherwise it's as Rick explained.
Many people talk about many things. That does not make them true. Virus' do not "attack" hardware.Quote:

I'm dying to see proof of a virus destroying a motherboard as you say. What "stuff" from the 'net can end up on your motherboard?
I even found the question intrigueing myself thinking I'd like to learn something... so googled a variety of ways and found nothing.
What do I get for my efforts? A reddie! :p
Funny how this works: When I'm plain wrong people are kind and correct me in posts, but 4 of the 5 reds I've got visible are plain silly. Oh well http://www.lunarforums.com/forum/Smi...fault/beer.gif
Well, y'know, you DO have some good connections here. You could clean up that undeserved reputation of yours. :)
Actually, I think a looooong row of greenies would look pretty boring, so the reddies mixed in gives the page a nice Christmas flavor. :p
It's technically possible for a virus to damage hardware. The recent PSP Brick virus proves that, and if you look back, the CIH virus a few years ago attempted to flash the BIOS of the infected system to disable it.
The problem with hardware damaging viruses is that they have to be highly specific in terms of the hardware and software they can actually be successful on. For most virus writers, there's either no payoff, or a very small one... Why fry someone's machine when it can become a Zombie that can be used to SPAM or hack others... for money?
In any case, running an up-to-date AntiVirus software package will protect you from these known threats - Although it's impossible to guarantee protection in the future from what "might" happen.
I'm more surprised that there are not more viruses out there targeting cell phones and PDAs.

Karim, if you won't install any security then you are in for a world of hurt!!
Deep Freeze will NOT protect you from virus infection, much less malware.
Philly, I must disagree with you, the viruses you mentioned attacked the systems firmware, not hardware.
I don't want to have a useless antivir to slow me and make me :mad:. Anti virus only keep bothering you with bannal messages all the time. And when a real treat is up the anti is out of date o somethingQuote:

Bear in mind that it takes less than 30 seconds for an internet connected computer to become infected !
If a 10k application can open your cdromdrawer why do u think virus can't attak hardwareQuote:

Gee, I don't want to wear a condom, but the alternative is a lot worse! If you think an A/V affects PC performance, imagine what the virus or spyware will do to it!! Stop being foolish and install a good A/V. I use E-Trust Armor A/V which doesn't seem to have an appreciable affect on performance.Quote:

An example of this is your BIOS. So a virus COULD target the BIOS EPROM, thereby rendering the hardware unusable. This might seem like its attacking hardware but its not.
That's a pretty geeky separation... and while I can see what you mean, in the case of the CIH virus, let me ask you: How many PC manufacturers offer a solution to fix a bad BIOS flash?Quote:

You're going to be replacing the mainboard of those devices to get them up and running again.
The bottom line is that if the CIH virus managed to corrupt a PC's BIOS, and you can't boot the PC, and there's no way to re-flash the BIOS... the hardware is dead because of damage caused by the virus.
It would be very foolish to use a network connected computer without any anti-virus protection. Even on a stand-alone machine, you usually would want a basic AV scanner available to scan removable media.Quote:

Just because yoiur data is on another partiton does not make it any less vulnerable.
Karim, as has already been pointed out repeatedly viruses attack data most notably your OS!!
Here's an excellent piece about how they work and what they do.
Read and learn !!
