Millions of Facebook, Twitter, Gmail and other users had their user names and passwords stolen according to a report that was just released from Trustwave.

The hack was done by a keylogging bug that was installed on computers worldwide.

By the time it was discovered, more than 93,000 websites had given up their users information. Researchers tracked the bug back to the Netherlands and found that the following popular sites had been affected.

318,000 Facebook accounts

70,000 Gmail, Google+ and YouTube accounts

The companies were told of the breach. Facebook, LinkedIn and Twitter notified and reset passwords for compromised users.  If you want to know whether your computer is infected, update your antivirus software and download the latest patches for Internet browsers, Adobe and Java.
