Serious hard disk problems

By computers ·
I am a private technician serving mostly homes and small offices.

I have run into a similar phenomenon on 2 computers within the last week, and wonder if it is virus related. In both cases, the computers had up-to-date Norton Anti-virus, and one had a clean install of Windows 2000 a week ago.

The issues seem to be:
1. even when shut down normally, upon boot, the "A disk check was scheduled" screen comes up, most often resulting in a hefty collection of chkfile fragments or the like. Cross-linked files are sometimes identified. One computer, running Windows 98, had collected 1.1 GB in temp files within the week.

2. When I placed the hard disk in my computer to check it, Windows XP reported that there was a chance that the data was corrupted, and that it will try to reconstruct. The result was total gibberish on the disk.

3. Various viruses detected and deleted or quarantined by Norton.

4. Requests to dail up by the computer.

The mbr seems to be totally ripped apart. A colleague suggested that this might be related the the MyDoom virus, but I haven't seen anything in the literature that indicated this.

Anyone seen this or have any ideas?

Although it doesn't resemble My Doom as outlined by the support sites, you could always run the mydoom fix found here anyway.

The other problames sound familiar to the BugBear worm the TEMP files may be due to ICMP traffic.

I would suggest running an online scan or trying different AV solution. Norton is more problematic than helpful in my experience, in fact that's the first program I delete when administering a workstation due to it's unresouceful use of the system.

Your suspicions are correct. This is not the MyDoom WORM, this is most likely a different virus.
MyDoom32 brings up notepad, and fills it with gibbrish, but it only does it once.
Try McAfee, Norton is about 92% effective and McAfee is about 95%.
They will all tell you they are 100%.
That is nonsense.
Read test reports out of Germany, to get a much more realistic view. (Do you speak German?)
This virus should be recoverable from.
Be happy. The really really bad ones, (Monk and family) actually delete Norton. (They are actually retrovirus attacks.)
MyDoom only prevents the PC from downloading antivirus programs, so, it also is not really really bad. (In my experience)

Thank you to everyone who have responded so far.

In terms of virus fixes that were run, the costumers had each run a number of them on their computers without finding anything.

I use the EZ Antivirus (EZ Armor Suite) from Computer Associates, and recommend it highly. It is not heavy in its use of system resources, and updates automatically as often as you set it to do (I use once every 12 hours). Often, by scanning a customers disk in my computer, I catch quite a few viruses that up to date Norton and McAfee have missed.

Another consideration to give to this is adware. There are some forms of adware that once in your system produce nearly the same reults (some of which you have described) as a virus.

Good Luck

Welcome to IE 6 SP 1 ! After installation lets' dial our ISP ! HUH ? Logged into network at the time ! System had a dialup connection configured when the upgrade started and IE "upgrade" defaulted to it, tell IE to never dial that connection (kills it real nice).

Win XP (NTFS) trying to read a FAT 32 possibly running a hybrid program to enable over 2 G HD. simple explaination on why it was giberish. 1.1 G is a sign of one of the IE upgrades, creates temp files and never deletes anything (software), upgrade further.

Chkdsk problem may be that start up file got marked as run on start up (depends on system/version how to make this happen) Win 98/ME a read only file saying run on boot, Win 2K locked start up file or is in the start up folder.

Another AV to consider is AVG from They have a free program that is very good for the money. It has also found viruses for me that Norton's or McAfee didn't find. It's worth a try.
