My Mrs was living in London when we got together, in Stoke Newington. It was fairly easy to get to from Sheffield (M1 then North Circular) and is nice and safe – the type of place that has a farmer’s market on the weekend. Tube from Finsbury Park which is 5 mins on the bus.
Or bus in to town, which is what she did as it was faster and easier
What’s a psp cleanup scan and where did you get it from? Something that mentions ‘Windows speed issues’ sounds dodgy as a dodgy thing, particularly if they’re asking for money to ‘fix’ them.
Take Dawson’s advice, and it’ll hopefully get rid of whatever is telling you that nonsense
