Kaspersky Blocks Google Advertising Sites

Kaspersky received an increase in complaints after it began blocking sites with Google ads yesterday.

After a dodgy signature was added to its databases the russian products began blocking some pages which display Google Adsense advertising, mistakingly claiming the pages contained the malicious program Trojan.JS.Redirector.ar.

Kaspersky admitted the mistake yesterday. "An incorrect signature was added to the company's antivirus databases on 25 January at 07:00 Moscow time (GMT+3). As a result, Kaspersky Lab products erroneously blocked some legitimate websites containing the link on script http://pagead2.googlesyndication.com/pagead/show_ads.js, which is used in the contextual advertising system Google Adsense," said the antivirus company in a statement.

However, Kaspersky moved quickly to fix  the issue. "The problem was quickly resolved and by 19:00 Moscow time the company's products had stopped generating alerts for legitimate Internet pages," Kaspersky said.

This is not the first time that anti-malware companies' mistakes have impacted on Google - In 2006 Norton Internet Security also blocked AdSense-based sites - Poor Google!
