Two months ago, we reported that Google AdSense was being blocked by Kaspersky Internet security software. That was fixed pretty quickly. But now, we are hearing new reports that the latest Kaspersky update is blocking Google ads again.

The alert people are seeing from Kaspersky is:

Virus detected
Severity: Critical event
Application: Kaspersky Anti-Virus 6.0 for Windows Servers Enterprise Edition
Version number: 6.0.2.555
Task name: Real-time file protection
Computer: DRxxxxxxx
Group: xxxxxxx
Time: 25 January 2010 09:26:00
Description: Threat detected: Trojware Trojan.JS.Redirector.ar. Object name: C:\Documents and Settings\xxxx\Local Settings\Temporary Internet Files\Content.IE5\CGQQTE3H\show_ads[1].js

They are being triggered by pagead2.googlesyndication.com.

We have threads on the issue at WebmasterWorld, Kaspersky Forums and Google Web Search Help.

I have not seen a comment from an official Google represenative or Kaspersky representatives as of yet.
