Recently, you might have noticed that every Google search results were showing the message “This site may harm your computer”. This was happened on Jan 31, 2009 between 6:30 a.m. PST and 7:25 a.m. PST. This was clearly an error.

According to Google, it was a human error. Google flags search results with the message “This site may harm your computer” if the site has some malicious code on the page. This protects us from visiting such web sites which can harm our computer. Google and StopBadware.org work with together to maintain the list of such web sites and this list is periodically update.

As per Google the error was occurred because of the following reason:
“the URL of ‘/’ was mistakenly checked in as a value to the file and ‘/’ expands to all URLs. Fortunately, our on-call site reliability team found the problem quickly and reverted the file. Since we push these updates in a staggered and rolling fashion, the errors began appearing between 6:27 a.m. and 6:40 a.m. and began disappearing between 7:10 and 7:25 a.m., so the duration of the problem for any particular user was approximately 40 minutes.”

In fact it was an error from their and but they worked hard to fix it as soon as possible. Thanks to Google team to fix this in short time.
