It appears every time I open the internet. It wants me to download a cleaning program which I know is a scam. I have tried everything, ccleaner, spybot, avg, adware. What else can I do?

Is the advertising trying to sell you, one (or more) of these useless products? If it is one of these, then it is an infection called Smitfraud that is causing the phony warnings. It is scam advertising trying to swindle you. And a link to a free removal tool is down at the bottom.

More infomation and another free removal tool called RogueFix can be found here:

Most “All-Purpose” malware apps such as AVG, Norton, Spybot etc unfortunatly can not remove or even detect this vile pest called Smitfraud.

Good luck.

I used to get that all the time when I used Yahoo! Mail.

Now that I switched to GMail, I don’t get any of those annoying advertisements.

Give it a try and see which you like better… the ads or the email!

Use pop-up bocker. Latest browsers have that feature. If you still have old browser download yahoo toolbar or google toolbar, they aso have pop-up bockers.
