I was considering using performance boosting software for my laptop but am reluctant after many incidents with the blue screen of death appearing due to the software messing with the registry.Despite renewing my internet security in December I was pestered by an advert from McAfee to boost my laptop’s performance and at an offer. There’s nothing to say it was only up until December as subscriptions are generally for year.So the discounted offer was a bit of a con with it being for under 10 months up until the internet security subscription runs out.I have finally decided to finish with McAfee and look somewhere else.
