Similarly it's been fairly common that when addressing someone's PC that was running slowly to find it had several AV and other tools installed because the owner hadn't de-selected the offers of 'Free' stuff in the process.
Similar with all the extra tools, either downgrading them to the free versions or uninstalling the combo versions (AV + FW) and re-installing only what you want.
The only really crafty ones were those where they had a series of tick boxes that used a combination of positive and negative wording to get you to not opt out of stuff but still not really and issue if you read them properly.
