Viruses That Hurt Hardware

Dooga
Recently, my aunt just got a virus... it's not a normal virus that deletes files or monitors my movements... it's actually a virus that does permanant damage...

What it does is that is starts up with Windows, and occassionally use up your CPU excessively, causing your CPU fan to speed up. Then it suddenly drops down, so your fan slows down in a sudden stop. This not only hurts your fan, your CPU, but it also hurts your Harddrive, since your hardware's heat is inconsistent and jumpy. This resulted in some "harddrive inconsistencies" which made her computer freeze after 10 to 20 seconds after startup... ouch!

Anyone else got or know anything similar?

I have never heard of such a virus, but it must suck to have it. Well good luck with killing it.

I haven't heard of a such a virus that does damage to hardware.

However, have you tried booting the computer up in safe mode (pressing F8 whilst booting up) and then running a virus scan in safe mode?

Safe mode basically only opens the system files a computer needs to use to run. Safe mode doesn't load up the additional files on boot like normal windows does.

I hope you manage to fix it in the very near future smile.gif

I've never heard of a virus of this kind. To my previous knowledge the only way a virus can damadge your computer is by somehow damadging your cmos chip which would prevent the computer from booting at all. blink.gif

Ive never HEARD of one, ive had thoughts about a virus that could alter the bios settings and overclock the pc causing it to overheat etc... probably wouldnt even work!! What a biatch of a virus you have though. Do as said above thoughh and you should catch it and if you have any other details like the name etc.. then could you post here so we can make sure we dont get hit too.

Would hate to have that virus sad.gif

When i got given my laptop from my uncle within a week it was doing similar things, random things randomly starting (hard drive etc) it would lock up at first, then take ages to load windows, then somtimes not be able to load windows then i got error message "no bootable devices found, no hard drive found error" i called dell they sent me a new hard drive and now its fine!

Yeah, there is possible that virus can hurt hardware. The most dangerous attack i think is when the virus write the BIOS. So our computer can totally dead.

if the virus not damage our hardware, and it may monitoring our activity. If the virus is created using Visual Basic, there is simple way to destroy it.

1. go to e.g: C:\Windows\System32 and rename msvbvm60.dll to whatever you want like msvbvm60.dll.bak.
2. restart your computer and the virus will error!.
3. List the file, and delete manually.
4. You can rename it back to msvbvm60.dll

Hope's help biggrin.gif

I've not only heard of this type of virus a computer sciences major friend of mine wrote a proof of concept "computer killer" as a part of his thesis. there are a lot of things that a virus can do to mess with hardware.

-processor modulations(stated above)

-faked dropped bits in ram. this affects typically network cards and harddrives. normally a chip of ram drops a bit of data every quadrillion cycles or so. no big deal. this one fakes dropped bits every 100 cycles with a chip that during post checks good. this eventually leads to bad data being processed and junk instruction being sent to hardware. this can be rather devastating during shutdown because it'll give harddrive addresses that are severly out of range.

-forcing open transistors. sending bad data through the various busses can damage the power supply by shorting between conections on the mother board.

-there's a technique called "drive bashing" that on all drives with moving parts. it is a raw read/write that forces the internal parts to crash against the edges of the inside of the drive. a symptom of this occurs naturally in harddrives. if your harddrive is clicking, get it replaced because it's about to die (unless it's scsi).

it would be very awful to have that kind of virus in your computer. Something that will damage even your hardware aint something anyone would pray to have.

A Report on a NewsPaper
(IDG) -- The first virus capable of damaging computer hardware is in the wild, but reports vary on whether it's a serious risk to most PC users.
The CIH virus was first discovered last month in Taiwan. Besides infecting Windows 95, 98, and NT portable executable files, CIH contains a routine that, when triggered, will overwrite the code in the infected PCs system BIOS, the software that's contained in a chip on the PC's motherboard and is loaded on boot-up to control the keyboard, disk drives, and other system functions.
"It flashes [the BIOS] with a bunch of garbage and basically renders your machine useless because if you [try to] boot up without a BIOS, your machine doesn't boot," explains Wheat. "You actually have to take the chip out and either have it reprogrammed or purchase a new BIOS chip. But you can't do a thing with your computer other than pop your door open until you replace your BIOS chip."

I think you should consider the other option that this might not necessarily be a virus. We should not be too quick to adjudge a system virus-infected when it starts acting funny.

Some system file may be corrupt in which case you could do a system repair with windows cd that came with the system. This you can do by booting up the system with said CD in the drive, select install option and when it loads up it will detect the existing windows installation, then you pick Repair installation - it will replace system files whilst keeping your files on system intact.

You could also alternatively Restore the system up to point where the system was working right.
