Experts: Only Two Weeks To Protect Your Computer

WASHINGTON -- Computer owners are being encouraged to run security tests on their machines within the next two weeks to ensure they have not been infected by two hacker networks that were seized this week by international law enforcement agencies.

The malware-driven network, called "Gameover Zeus," lifted banking credentials from up to 1 million infected Microsoft Windows computers, according to the United Kingdom's National Crime Agency.

The Wall Street Journal's Market Watch reports the U.S. is home to the highest percentage of Gameover Zeus infections, at 13 percent, according to the Symantec security company.

A second network, using Cryptolocker malware, took command of more than 234,000 computers, demanding ransom payments to unlock files.
