Logon Problem at the welcome screen

Hi,

I was having some problems with a whole host of trojans that had taken a
hold of my computer. I did have uptodate antivirus and it was effective in
finding and removing them, however one of them always managed to evade this
and would bring up a message once I had logged on. Its process name was
winupdate86.exe which was always in the folder System 32 in the Windows
folder. this process blocked the task manger and the registry editor but with
Windows defender i was able to look at the currently running programmes and
see that it was this winupdate86.exe that was the cause.

I then also noticed an exe programme that was on the startup list called
winlogon86.exe which i thought was the reason that this winupdate86.exe was
always there whenever i switched on my PC. and so i deleted it.

Now when i switch on my PC i can get to the welcome screen and then when i
click on the account(there is only one account) it says "logging on" then it
just logs off...hence i think i have deleted a critical file for the logging
on process.

I do have the Windows recovery disk from Dell and easy option would be to
reset to the factory settings. but if i could use the recovery console to
just repair the logon file I dont have to lose my work.

Is there anyone out there who can tell me the spcific code lines to use to
repair/copy a file. I have used the chkdsk command but as i have no knowledge
of command promt i am stumped as to what to do next.

Please help
Many thanks

Reloading Windows is the only way for you to get a stable installation.
Everything else is a waste of your time. Remember to format all partitions
of your disk during the installation process. Post again if you need advice
on how to save your data files before going ahead.
 
Hello Pegasus.
I have a similar problem. My computer was also infected by a
worm.win32.netsky as well as a trojan. I was able to download an update to
my McAfee antivirus program as well as McAfee's Stinger program to find
malware/viruses. They seemed to work but now when I try to log on XP then
logs me off.
I was intrigued by your answer, can you elaborate on how to save the data
files before proceeding,
Thanks - Ernie

There are several ways to retrieve your files without using Windows. Here
are some of them.
a) Restore them from your backup. If you don't have one then this is the
time to review your backup policy. Important/irreplaceable files must never
be stored in just one single place. Doing so is asking for trouble.
b) Remove the disk, then connect it as a slave disk to some other Windows
PC.
c) Remove the disk, then install it in an external USB case, then connect it
to some other PC.
d) Boot the machine with a Bart PE boot CD (or similar), then copy the files
to a slave disk or to a USB mass storage device.

About a): The 2.5" disk you might buy for methods c) or d) would be a
low-cost but highly effective backup medium.
About b) and c): If this is a laptop then removing the disk can be as simple
as removing a cover from the underside of the laptop or as involved as open
heart surgery. It all depends on the laptop.
About d): A Bart PE boot CD (http://www.nu2.nu/pebuilder/#download) takes a
fair effort to make but is quite fast in booting up. A UBCD
(http://www.UBCD4win.com) disk is easier to make but takes forever to boot
up.

Just to add another option here... you can also use one of the many
Linux Live CD's that are available to copy files from your infected PC
to an external drive or a USB thumb drive. After all a file is just a
collection of 0's and 1's and if an OS can read the file and write an
exact clone of it, that's all that is needed.

Would you rather just fix your PC?

Attacks to the XP login process are quite common and usually easy to
fix with no data loss when properly diagnosed.

Do you have an external USB case to move your HDD or do you have
experience in slaving a current HDD in a working computer?

You will need a genuine bootble XP installation CD to create a BartPE
or UBCD4Win CD - do you have one?

If you decide not to fix your current system, you will still need a
bootable XP installation CD to reinstall XP after your data is moved.

If you have a bootable XP installation CD, why not just use it to fix
your current system?

If you don't have a bootable XP installation CD, it still may be
possible to fix your system.
 
Hello Jose,
Thanks for your post and help.
I have no experience in slavin a hard disk.
I do have my original Dell installation disks including the Reinstallation CD
I tried starting in safe mode and used the Last Known ood Config with no luck.
If i put in the reinstallation disc is there a way to repair Windows without
losing my data?
Also i am interested in the BartPE will that allow me to pull of my files
before installation.
