Then, if you click on one of those link it will turn result that says "Warning - Visiting the website may harm your computer!". See the images below.
If we click to all link came from the result it will give a warning of a fake malware. This also include search on images. All the link will return result from the following URL example.

The number of desktops and servers infected by the "downadup" worm has skyrocketed to nearly nine million, according to security firm F-Secure.
That is an increase of more than six million since Thursday last week, when F-Secure warned that the worm was affecting corporate networks and spreading rapidly.
The worm, also known as "conficker", is a large family of network that causes various problems, including locking network users out of their accounts.
F-Secure said in a blog that the spread of the worm was "amazing" and that the situation was not getting better.
The firm ascribes the rapid infection rate to the fact that there are several different variants of the worm.
The most common variant F-Secure has been tracking is creating 250 possible domains each day, the firm said.

Trojan horses are very common these days. As their name implies, they often sneak into a person's computer because they come packaged as a useful program like a screensaver or something. Then, once they are installed on the computer, they open up ports (like a secret door to the internet) on your computer and allow other types of infections to sneak in. These other infections come in totally unannounced. You won't realize they are there until your antivirus program happens to detect them. By then, it is possible that their intended damage has already occurred.
This is why it is important to have a firewall on your computer. The firewall increases the computer's security by closing all of these doors and locking them. The firewall only allows doors to open that are used by common programs like web browsers and email. For another port (door) to be opened, the firewall program usually asks for permission from the computer user. That's why you get the messages popping up in the lower right hand corner of your computer asking if it is okay for something to happen.
Another type of infection is the computer worm. Computer worms are like viruses except they do not come attached to any other files. These worms can move from computer to computer across a network. They move from computer to computer by going through open ports. This is the biggest benefit of having a firewall to keep those ports closed and locked. The internet is one giant network. So, just by being connected to the internet, your computer is exposed to this type of infection.
Adware is another type of program all together. Typically, these program come bundled with other software as well. When downloading some music sharing software, if you read all the fine print you would see that the reason that software is free is because it comes bundled with an adware program. The adware program will make pop ups come up on your computer. It might also modify your internet browser so that your search results are influenced in some way that benefits the author of the program.
I can honestly say from experience that you can guarantee getting an infection by using your Windows based computer to browse the internet regularly if you do not have an adequate firewall on your computer. The firewall is far more important than your antivirus software itself. This is one of the most misunderstood computer security issues among the general public.
