Secure Antivirus Pro enters the system through Zlob or Vundo trojans and installs its ‘trial version’ without the user’s permission. It then stars loading fake security warning messages and pretends to perform security scans and find various infections and parasites.

Secure Antivirus Pro imitates to scan your computer and displays fake reports and messages, such as:

“It seems that your computer is infected with W32:Virut virus. This threat has been designed to steal money, Internet accounts, send massive amounts of spam, and commit various kinds of fraud.
It is recommended that you remove this threat immediately to avoid participating in criminal activity.
Do you want to remove Virut now?”

Secure Antivirus Pro is just a scam, which tries to fool you into buying its non-existing full version.
