This is a more serious threat... usually virus are not that harmful even if they are really annoying.

I will start to fear when they will attack my motherboard Bios... until then, AVG is doing the job.

fix = fdisk /mbr

Not necessarily accurate. If the system is still infected, repairing/replacing the mbr won't matter as when you boot back into windows it could just reinfect your system again.

Like red said, a virus is a virus, no matter how you put it. They all basically do the same thing - mess with your copy of Windows, not going any deeper than the Hard Disk. Until the day comes when someone finds a way to get past the HDD/Software level and truly embed a virus into the RAM or Bios, I'm perfectly happy. Besides, you shouldn't really have to worry as long as you're not doing anything illegal or watching pr0n and the like.

@redgarl
I do believe a while back there was a virus that did exactly that. It was early on when mobo makers started using flash to store the BIOS. Now days, they have a removable chip that you can replace (or high end systems with two separate copies of the BIOS) in the event that you flash improperly, or heaven forbid, another nefarious virus figures out a good way to wipe it out on you.
Back then, the virus basically shelled your mobo and you had to get a new one.

Google the CIH Virus

not to mention formating your MBR would sacrifice your OS settings.. thus making you reinstall your OS.

True, but that would at least let you run an antivirus program and find the dll. That avoids having to wipe your drive and lose everything.

So pull the drive, scan on another system, boot into recovery console after virus is removed, boot to recovery console, bootcfg /rebuild, fixmbr, reboot.

 

[ohiou_grad_06]

No need for that, boot from a rescue disc such as ubcd 4 win. Also, fdisk command may not be necessary. I think if you boot from a Vista or Win7 disc, that it can detect and fix things like that correct?

 

[psyic]

Mitch's solution is really the most elaborate and correct way to do it. I would advise another scan after those steps in safe mode within the machine, perhaps with MBAM.

All fdisk /mbr would do is clear the mbr (more or less), not really do anything directly relating to fixing it.

 

[physx7]

OTLPE + fixmbr = win

It sucks how Windows, having one of the largest market shares of Operating Systems, is always under constant attack.

When UEFI comes out, if a virus was to take over THAT firmware then your computer would be screwed, could do almost anything!

 

[chickenhoagie]

next thing you know they'll have viruses that are stored in the capacitors of ur power supply and cause a mass overload, shortening the circuit in ur wall which will in turn make ur electricity go out in the house. Hell, pretty soon they'll find a way to give ur computer AIDS.

/kill C Drive

I thought Win 7 was meant to be uber secure, with permissions to install stuff and such? This sounds like the bad old days again, when will they learn and implement tighter security?

 

[Strider-Hiryu_79]

Oh no! My downloaded pornz are at risk!

Formatting your MBR does not sacrifice your OS settings in any way.

Another alternative would comprise of loading a pre-installed environment via disc/flash drive, then running a virus scan from there.

Preferably the newest Windows PE where you can run the recovery console right after.

whats next a virus that drops child pron on a pc.

 

[rkelly1]

Theres one out there. i lost a desktop motherboard to it luckily it was a junk computer

 

[Tamz_msc]

I thought that boot viruses were uncommon these days because the OS protects the boot sector.
