Stop downloading random things and you won't get
adware.
Run Malwarebytes, scan your PC and remove any infected files. Scan your PC with different Antiviruses to see if they detect anything (I suggest Avast! Antivirus, refrain from using McAfee) and remove any infected files found. Run CCleaner or completely wipe your web browser's cache. Install AdBlock Plus, don't click on any foreign links or any advertisement. If the app doesn't uninstall through your web browser, try uninstalling it from control panel, and if that doesn't work, you'll probably have to find the root folder, delete it, and delete any registries that direct to the root.
If all your problems still persist, download TeamViewer 9 and try to get live contact with me whenever you can and I'll remove the adware for you, but don't resort to this option until you do everything above. If it didn't work then that's when you contact me. Try to tell me what you last installed or were last doing before the adware got onto your PC.
If you do need to contact me, try some of my contact lists.
