When I turned my computer on, it claimed it was infected with a trojan virus and a worm. I went through and scanned, and found only one file, which I deleted. But it still fussed, so I decided to restart it. Now it is crying about a spyware.cyberlog-x. I scanned, but found nothing, but my system performance says it has been lowered by 47% <<;

So, are their any free online spyware deleter things that any of you could recommend?
