I am going to buy xoftspySE to delete the trojans popups on my PC. I dont know if it works or not. Somebody said it sucks, and i dont believe it. xoftspySE is the only one i can truth because it describe exactly my problem–>http://fix-slow-computer.com/spyware/how-to-remove-unknown-trojan-message-unknown-trojan-remover/. Some advice plz.?.

Chosen Answer:
Xoftspy is scareware. It will “find” malware on even a virgin system. There’s nothing that Xoftspy does that you can’t get for free.
Before you flush down the toilet, try Superantispyware for free:

I agree with heebus. Xoftspy is a waste of good money.
That link you provided about the phony “system warnings” indicates a Smitfraud infection.
Any “warnings” are fradulant and a scam.
Almost all “general purpose”,”all-in one” spyware and virus removal programs such as AVG, Norton, McAfee or Spybot S & D cannot remove it.
The standard tool to remove this pest is SmitfraudFix. The full removal procedure and the free removal tool is here:

After running SmitfraudFix, to clean-up any remaining infection traces, scan for trojans, adware, cookies, and spyware and remove (free online scan, no downloaded program) with Ewido Online Scanner ( now known as AVG Anti-Spyware). This is NOT the same as AVG Anti-Virus. Press “Scan your computer now online and clean it for free!” on the left.
