hello, i got a problem usin windows XP on internet. when i enter to a site it gives me a pop-up like: YOUR PC WILL SHUTDOWN AND RESTART ON 60 SEC. WHAT can i do, what is this, how ca i resolve this?? help plzzz..

Does the pop-up say that the Remote Procedure Call service has stopped unexpectedly? You probably have a virus. Try this. cursum perficio

A simple fix. Don't go to that web site any more.

Or is the error indicating a problem with lsass.exe? If so, it's probably a virus like Roy said. Sasser is my guess. What anti-virus program are you running? Soylent Green is PEOPLE!

Is it restarting really after 60 seconds?I think it can't(if you are not opening any file from web).Try to install popup blocking software if your browser hasn't and always keep in mind`don't respond every windows that appears,in some of them you can see a button with text "scan for viruses" or something like "your computer is infected,allow me to scan it for free",don't respond messages like this,this is only text,and it can't do anything,only send you to site with viruses,malware and hacks. Don't worry man about that "s---",even if it appears in your desktop and says "your computer is infected with the virus and you can't do anything".

search google for"spybot search and destroy"

It's a virus, and as said, probably sasser. Get removal info from whatever AV program you're using. If I had more time I'd do it for you. Do a Google search. Also find out why your AV program isn't doing its job.
