Did you try a regular uninstallation via Control Panel followed by the MCPR cleanup tool? You can always restore the sidebar later using an sfc /scannow for instance. If it's disabled by the software removal then there was something wrong to start with.
You can turn off the antivirus and firewall components but you'll still be bugged to buy the product I'm afraid as that can't be turned off.
What operating system and service pack is this? With that info I could research repairing the sidebar.
I just did a regular uninstallation, without MCPR cleanup tool. Do you think that's necessary as well?
As for the sidebar, at the risk of sounding like a complete layman: I don't really know what an sfc/ scannow is..
My operating system is Windows 7 Home Premium and it came with Service Pack 1.
Thank you for being willing to look into it!
It should be OK. If you install other software and it detects McAfee still then post back and we'll go from there.
The sfc or System File Checker is a useful tool to repair an installation when something malfunctions.

A good way of avoiding having to use it is to never use registry cleaners, be careful where you surf and what you download to avoid infection and keep Windows totally up to date, all of it.
I uninstalled Mcafee again, but this time I didn't tick the option of deleting all files and now it seems to work properly. I don't get any pop ups anymore and my sidebar is still working, so it seems that my problem is fixed.
That's good. I'm now wondering if perhaps it had quarantined part of the sidebar for some reason. I guess we'll never know.
