DNSChanger - This little, mean piece of malware appeared last fall that could disrupt your access to the Internet and redirect you to malicious/fraudulent websites, where cyber-criminals could either steal your money or push more malware/spyware onto your computer. The FBI knocked out those that were responsible, and they have put a 'safety net' of servers in place to make sure those that are infected can still surf the net. On July 9th however, the FBI will be taking those servers down.
