The Internet is still not safe, and the risks may lie in unexpected places. While companies like Google continue to ramp up their defenses, a surprising number of nefarious websites still slip through.
Google last week released numbers that revealed the problem. In 2011, Google suspended 824,000 advertising accounts that violated its terms of service banning misleading claims, ad spam and malware -- more than three times the number of accounts in 2010.
"We find that there are relatively few malicious players, who make multiple attempts to bypass our defenses to defraud users," Google said in a blog post. "As we get better and faster at catching these advertisers, they redouble their efforts and create more accounts at an even faster rate."
