am I infected? Google results full of spam

regardless of what I search (mostly computer related problems) all that comes up on Google is spam results and ads that have an orange box with the word "ads" and all I get is junky results and/or spam results. Googling anime characters even returns spam results. I have Ad Block Plus but Google is still full of ads and spam when I search

Hi,
You might try safe mode with networking and test,
Shut down your machine,
Power up and Tap the F8 key continuously until you see a black page with white text,
Use the down arrow key to toggle to safe mode with networking/ hit the enter key.
Just for the record the download button to use is "Download now @ Bleeping computer" not the Big green one,
Cheers.

Download the AdwareCleaner (from the site given above) on another system and put it on a USB stick or an SD card. You can run it directly from there - it needs no installation. It is less than 2MBs.

Thank you whs, sorry for the very slow reply. Follow whs's advice.

No problem. Looks like we lost the OP.

Op? Sorry.
