strange virus?

[alidabiri]

hi,
i recently installed win-xp on my machine. after installation (a few days later). i keep getting these strange pop ups that looks like coming from windoes:
"your system is infected. visit registryalert.com" or regfix.com or regfixer.com" or pccleaner.com. the last message says that windows will shut down in 30 seconds, and shuts my system down. is there anyway i can get rid of this? is this coming from windows? or ms-new anti spy? any help would be appreciated.

It's spyware/trojan. Do you have Spybot search and destroy? Do a goole search for Spybot (freeware) Or you can do a HiJackThis scan READ instructions here: https://www.techspot.com/vb/topic17297.html and post and hopefully RBS will take a look when he gets a chance. (it can be done by yourself if you read carefully).
