Clearly, gauwzaken.com has a clear phishing attempt:
Once your PC is attacked by gauwzaken.com, you may get such pop-up warning all the time:
"The page at www.gauwzaken.com says:
WARNING!
Your system has (13) Virus!
The Virus may comput you data.
Please follow the instructions to remove the Virus"
It's clearly a crappy attack, the English is all screwed up and you'd never trust a popup anyhow. What you need to do is to remove gauwzaken.com from your system as soon as possible. If not, gauwzaken.com is going to mess up your browsing.
