As a precaution I moved this to Malware Discussion > Home User Assistance and removed the attachment, replacing it with the image as part of the post.
As it turns out Webroot is legitimate software. You mean that Uninstall button in the McAfee UI wont work?
How about uninstalling Webroot from Control Panel > Programs and Features? Then try your installation again.
Here are Webroot's instructions:
Move your cursor to the bottom right of the screen to open the Charm Bar menu. Click Search, then type "appwiz.cpl" (without quotes), and press Enter on your keyboard.
This will open your Control Panel to the list of all programs currently installed on your computer.
Scroll down the programs list until you see the Webroot security product.
Click the Webroot security product entry once to select it, then click Uninstall/Remove.
When asked if you are sure you want to uninstall, click Yes to continue.
If prompted with a CAPTCHA, enter the requested characters and click Enter.
Thanks Ex Brit.....much appreciated!
