I had McAfee installed on my laptop, initially as a promotional free 30-day subscription which I continued, and it would bring up multiple pop-ups every time I used it - so unnecessarily disruptive. It also repeatedly changed my preferred search engine against my wishes. After a year, the plan auto-renewed at a far higher price ('Secure VPN' + 'Virus protection pledge', for a total of £99.99). I was horrified, deleted it and requested a refund. Now that my subscription has expired, they email me every day with dramatic subject lines such as '42 million threats could find you!'. Meanwhile, I've moved on to Norton and I'm having a much better experience. I'm not in the habit of writing reviews like this but I wanted to warn others!
