Hi, UniSales is an adware program or we say potentially unwanted program that keeps displaying a lot of ads on your computer. To remove it, you can follow the steps below:
1. Check Add/Remove programs in your Control Panel and remove any unknown programs/toolbars.
2. If pages are opening up each time you start up Chrome, check in Wrench > Settings > On Startup > next to the radio button for Open a specific page or set of pages, click on Set pages > remove any unwanted URLs by hovering over the URL until you see an "X" appear to the right side of the URL.
3. If pages are opening up when you click on the Home button, check in Wrench > Settings > Appearance > select the Show Home button checkbox > check if the URL that appears below it references anything unknown.
4. Also check that there are no extensions installed that may be causing these changes. Go to Wrench > Settings > Extensions > if you see any unfamiliar extension that you do not remember installing, try disabling/removing the extension to see it was causing these changes. To disable, uncheck the "Enabled" checkbox next to the extension. To remove, hover over the extension until you see a trash can icon appear, and click on the icon.
5. Press Win + R on your keyboard>type in regedit>hit Enter>click Find...from the registry menu>input Unisales to search for its malicious keys and remove all found items.
6. Go to the local hard disk C to find out and delete any files related to this adware.
