How to kill Blaster (Lovsan)

[Frankie Deschacht]

I have apparently been infected with the Lovsan A (Blaster?) worm, after an
update from the MS updates site went pearshaped.
AVG antivirus recognises it, but can't remove it,I have also installed patch
KB824146 and my Firewall is on, to no avail.
How can I get rid of the monster please ??
Thanks,
Frankie.

Does it say anything about System Volume Info? You may need to turn off
system restore, reboot and then turn restore back on.

Try this link for the removal tool:

Thanks Unknown,
but I have already gone to that site and I don't understand much of what
they tell you to do.
Besides, it looks like the removal tool is a Symantec Update file, the
problem being that I do not use Norton but AVG as my AV software.
Where do I go from here ?
Thanks,
Frankie.

Look for blaster.exe in /windows/system32 and delete it.

DISCONNECT the subject computer from any network IMMEDIATELY.

If necessary to stop the reboot process:
Start/Run
Type "shutdown -a" ENTER

Install or enable a firewall IMMEDIATELY, before connecting to the
internet:

VERY IMPORTANT to follow ALL steps, closing ports or installing the
patch is NOT enough.
Download the patch and regedit referenced in the article below.
You may need to do this at an uninfected computer and burn to CD or
save on floppies.
Each file is small enough to fit on a floppy.

Follow this to clean and protect your computer:

After this is resolved prevent similar occurrences by installing ALL
Critical Updates from Windows Update.
Keep antivirus up to date and run at least weekly.
Install or enable a firewall.
