Alert: Microsoft Security Essentials SEO Poisoning

[kgun]

When a user browses to the compromised Web sites, so long as they have been referred by a search engine, they are redirected to malicious Web sites with domain names such as computer-scanner21 and computervirusscanner31.

I am very sceptical when Microsoft sends out security warnings. This is no joke:

1. My bolding: Why don't MS send out a security warning of using Internet Explorerer in red? No, it is no joke until someone has convinced me that Internet Explorerer is the most secure and safe browser.
2. Is it hidden ad for their products?
3. Again my bolding: Regarding searching, you can use Google safe search that will filter out some problematic sites.

From 301 Redirect Script for SEO - McAnerin International Inc. we read

"JavaScript is the second type of common client side redirect. Unlike the meta-refresh tag, a search engine will ignore a JavaScript redirect and stay on the page.

Some people have decided that they could use this behavior to spam the search engines, by stuffing keywords on a page and then using a fast JavaScript redirect to move people on to the next page while allowing the spider to stay and index the spam page.

Google figured out how to detect this tactic in the summer of 2004 and as a result a LOT of websites lost rankings, resulting in at least one infamous SEO firm getting a class action lawsuit started against them, as well as making them look really bad.

In short, JavaScript redirects do not work for search engines, and using them can possibly get you banned from a search engine, depending on the circumstances."

Quite possibly someone has found an alternative method of doing this.
