Virus in microsoft Patch

[Alan]

Last night I was having problems with the RPC shutting
down my computer automatically if I connected to the net,
having phoned my ISP I was directed to a patch on the
microsoft website. Upon installing this patch I was
informed by my antivirus software that I had contracted a
virus from this patch. So be warned, dont assume microsoft
files are clean.

Anything you obtain from Windows Update is guaranteed to be virus free.

Of course, if your computer was already affected by a virus, that virus can
easily spread to something you download.

Alan;
You already had the virus (worm).
That is what was causing your issue.
Now you can blame Microsoft for your troubles or you can install the
patch (should have been done a while ago.
Enable firewall (why wasn't it enabled)

Follow this carefully to fix the computer:
You most likely have a worm W32.Blaster.Worm
DISCONNECT the subject computer from any network IMMEDIATELY.

Install or enable a firewall IMMEDIATELY:

VERY IMPORTANT to repair, closing ports is NOT enough.
Download the appropriate patch referenced in Ron Martessl article
below.
You may need to do this at an uninfected computer and burn to CD or
save on floppy.

This is the IMPORTANT fix by Ron Martell:

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.

Here is a more complete solution:

You have probably received the following error messages
when using your computer:

"This system is shutting down. Please save all work in
progress and log off. This shutdown was initiated by NT
Authority/System."

"Windows must restart because the Remote Procedure Call
(RPC) service terminated unexpectedly."

This is a known security issue which was first found on
July 15. There is currently an Internet Worm that is
taking advantage of this security issue. Microsoft
published the patch to fix this issue on July 16 for all
of the affected systems on our web site. For more
information, please refer to the following page:
