Win XP Internet Shutdown

I have Win XP Pro and have recently been getting a message on scrteen which reboots my computer only when I am on the internet. I use a dialup connection and it doesn't matter which browser I use. The message is:
Windows must restart because Remote Procedure Call ( RPC) serer terminated unexpectedly.
Shutdown initiated by NT AUTHORITY\SYSTEM

I don't use nor never have used Windows NT

If anyone can suggest a solution to stop this happening I will be absolutrly delighted !

 

You have the Blaster Worm. Follow this link for resolution.

I am very surprised there are still unprotected PCs out there, as it has had so much press at the time. Antivirus updates have included this for some time now. What AntiVirus are you using?

 

You have the Blaster virus
The FIRST thing you need to do is ensure that you have installed ALL Microsoft Updates.

SECOND:This is an ABSOLUTE PRIORITY,get a good firewall,read it's documentation so you know how to set it up and make sure it starts on bootup.

An excellent FREE firewall,called ZoneAlarm,can be found here:

THIRD:Another ABSOLUTE PRIORITY is to get a good Antivirus program and AVG is as good as it gets.You can get a free copy here:

(I use these 2 programs on my machine and have had no virus,trojan,worm or browser hijacking in over a year)

Spybot Search & Destroy is a free program that does a good job and can be found here:http://www.safer-networking.org/index.php?page=download

Another thing you can do is an online system scan from here: http://housecall.antivirus.com/housecall/start_corp.asp

FOURTH:Before running ANY scan for virus,trojan,worm etc. you should ALWAYS turn off System Restore as copies of everything you are trying to get rid of are in System Restore just waiting for you to put them back where they came from in the first place.

This will delete all restore points on your machine,but if they are infected you don't want them anyway.

FIFTH:Another good thing to do before running the scans is to clear out your TIF and other temp files.
In Internet Options, under the General tab click the Delete temporary internet files, choose to delete all Offline content.
Also, go to Start - Search - Files or folders - in the "All or part of the file name" box, type: *.tmp and choose Edit - select all - File - delete.
Do the same for "Cookies"

Empty the contents of the C:\Windows\temp folder and C:\temp folder, if you have one.
Empty Recycle bin.

SIXTH:Now you are ready to scan your system using the above listed Spybot and Housecall

Make sure that you update antivirus,firewall and scanning programs on a regular basis,and particularly,just before performing a system scan.

Once you have cleaned your system and have it running the way it should,turn System Restore back on and create a fresh,clean restore point.

 

Many thanks for your prompt assistance. I use McAfee antivirus ( subscription version ) which I update every few days. From another response it appears that having "System Restore" turned on may be the answer to the problem as McAfee keeps detecting and deleting the b....thing, but it keeps coming back.

Will turn off and delete restore points, do a virus check and a "Spybot" check and hopefully peace will again return.

Thanks Again
