Virus infected PC

By freemindneo ·
An HP PC, running Win ME, seems to be infected with a virus, it will not start Windows. I've tried to reinstall Win 95, Win 98 and Win XP and it appears to be installing the software but when it stars running Windows, it freezes. I've reformatted the hard drive twice.

Can a virus be removed by reformatting?

How can a virus be removed without being able to start Windows?

Thanks!

Many viruses will be removed if you perform a FULL format. format c:/u
Even better, is to boot from a write protected startup floppy, and run fdisk.
Start with fdisk/mbr This repairs the master boot record in case it is infected.
Then, use fdisk to delete ALL logical drives and partitions.
Re-boot, run fdisk again to create the partions you desire.

This sounds more like a hardware problem to me.

My first thought is incompatible or bad memory.
I have seen RAM modules pass the POST test, but not allow Windows to load.

Next, check any plug-in cards. A bad modem or NIC are common causes of systems not booting.

In order to answer how to remove a virus from DOS mode, it helps to know the specific virus.
There are good knowledge bases with lists of virus'es, and how to remove them, at both Symantec's and McAfee's web sites.

Norton Anti Virus 2003 allows you to boot the computer from the NAV CD ROM and peform a DOS scan to detect and clean before actually performing the Norton installation. The same can be done by creating a NAV rescue disk from another PC that has Norton installed. Then boot from the rescue disk and perform the DOS scan.

However I agree with the other answer, I dont think this is a virus problem. I would unplug and remove all non-essential hardware components and try different memory to see if this makes a difference. If it boots, then start putting things back one at a time.
