Popups appear when I move the cursor some text on websites, which has never happened before. These ads claim to be powered by coupondropdown. I'm not sure if these ads are malicious untile I read this page showing the hazards of coupondropdown. Well, the pop-ups I'm suffering are triggered by malware. So I want to know F-secure online scanner can help me solve this problem? You may think the problem is redundant, but I just want my PC to avoid more danger. After all, I'm about to download the sanner.

It's possible that your browser has received an unwanted Add-On from somewhere, so the first thing I would suggest is to check your browser Add-Ons list and see if there's anything in there which looks suspicious. Also check any existing Add-Ons which you already know about for recent updates, which may have bundled in the adware (check add-on Options, etc).
I'd also recommend running a scan with Malwarebytes which will hopefully find and remove any adware which has crept into your PC.5 Like
