The paid search ads of google had a tough time after a malicious illegal attack using AdWords accounts became public knowledge.

Criminals used AdWords to straight web browsers from side to side third party website that attempted to contaminate the PC. The attack would take benefit of a error in Internet Explorer to dive a backdoor and a post-logger onto PCs; the malware particularly looked for identification for 100 banking sites, according to Exploit Prevention Labs.

Google's Inside AdWords blog has a fresh post available, with the company's reply to this egregious abuse of its product. They caught and shut downed AdWords accounts linked to this attempt, and monitoring the situation.

"We vigorously work to find and delete sites that serve malware in both our ad network and in our search results," the post said. "We have manual and automated processes in place to find and put into effect these policies, and products such as Google Toolbar that aggressively seek out and alert users when they browse malicious or suspicious websites."

It doesn't look like the processes worked. Exploit Prevention Labs start noticing the against the law AdWords placements on April 10, a full two weeks before Google closed the offending accounts. Those ads likely ran for a time before Exploit Prevention Labs selected up on them.

Google also gave the standard security advice to users about securing their systems with up to date virus shield, and altering complex passwords frequently. Good advice, but it's also a deflection from the broader hope issue that people will have with paid search ads now.

Searchers were making very inoffensive queries on Google that twisted up these malevolent AdWords ads. These were searches that turned up phony ads for the Better Business Bureau and Cars.com, neither of which be inclined to be associated with the less than Zen cartsites usually associated with drive-by infections.

The circumstances is also going to make people who have been affected with attacks like these, without browsing any unusual websites, to doubt if this is how their computers got threaded with a nasty Trojan. This is not the first time criminals have tried to exploit AdWords, according to Google's stated practice of seeking for this behavior.
