I am sorry your PC got unwanted software. The correct download button is the one that looks like this:
The Winaero website has many ads. Because all the apps there are free and no one donates, the only way to earn revenue is via ads. You may have clicked on the wrong "Download" button which might actually be some ad which tries to install sneaky stuff and crapware which hijacked your machine.
I don't tolerate apps with crapware either but the apps themselves from Winaero are clean, they don't even have an installer, most of them are portable. However clicking the wrong Download button may have caused your PC to get infected.
You can use the Ghostery add-on for whichever browser you use (
https://www.ghostery.com/) to block ads. If you are using Internet Explorer, turn on Tracking Protection from the Tools menu and download a Tracking Protection List from
http://www.iegallery.com/en-us/trackingprotectionlists. Once the ad servers are blocked, only the correct Download button will show on that site. Then download the Winaero.com tools, you won't get unwanted crapware. The tools themselves are great and do not install anything else.
At this forum, I think you are the first to complain but I will take steps to prevent others' PCs from being infected by informing what they need to do to prevent clicking the wrong Download button when recommending Winaero.com tools.
