One in seven home networks in North America suffer from some type of malware infection, a new reports said. So, what does that mean when someone takes a laptop home at night to work on project and then plugs into the home network to look up some data?

Half the threats detected during Q3 2012 consisted of spam zombies or banking Trojans while the remainder were mostly adware and other lesser threats, according to a study by Kindsight Security Labs. The basis of the study was on data gathered from the security firm’s service provider customers.

The one-in-seven infection rate recorded by Kindsight in the third quarter is an improvement by one percent over the second quarter, according to the report. While that is an improvement, home networks suffering from malware infections could present a problem for work at home scenarios for workers.

Consumers most commonly suffer a malware infection after visiting websites contaminated with exploit kits via drive-by attacks.

Kindsight names the ZeroAccess botnet as among the worst problems faced on the Internet. ZeroAccess was the most active botnet in Q3, with more than 2 million infected users worldwide with 685,000 in the U.S. alone.

These bots engage in a sophisticated ad-click fraud scheme that each day generates about 140 million fraudulent ad-clicks and 260 terabytes of network traffic, according to the report. ZeroAccess could be costing advertisers $900,000 per day, the report said.

The second most active botnet in Q3 2012 was TDSS/Alureon family, also called TDL-4.
