I was in a bind, having inadvertently opened a scam email that I had already confined to my Spam folder, and that sent a maelstrom of malware on my system. I bought a Restoro package originally to sort an email issue I was having, which is how this error and all the malware came to light, so I thought it well worthwhile investing in a further service to allow Restoro to thoroughly clean my laptop. That is now done and, apart from my Outlook server which I have to check on, I understand my laptop is back to running healthily and - I wait to see - performing better than ever. A well-worthwhile service that I can recommend!
