My yahoo email spammed all my contacts with a scam email. Yahoo put me on to a company called Techy-9. They charged me £150 to supposedly clean up my computer. They used remote control and downloaded Mackeeper
After sending out a spam email to everyone of my email contacts I contacted Yahoo on the phone and they put me in touch with someone from Techy-9. He talked me through downloading a program that gave him remote control (Team control?) and downloaded Mackeeper to show that I had a serious problem....2000 files that had a virus and everything in the red! They then charged me £150 which I paid by Paypal to clean up my computer. I left the computer on so that they could do this. When I got back i restarted my computer, to find that all my folders and contacts on Yahoo mail had been deleted and when I went onto Mackeeper everything was still showing red.
I realise that by downloading any clean up apps your opening up a can of worms! Apps with Trojans. I changed my Yahoo mail password
The company have now phoned back and apparently it was one of their technicians that has 'pocketed' my £150 and that they will be refunding it.
I have managed ( I hope) to remove the apps from my application folder and put them in trash and emptying trash.
Be careful when you use an 0800 number to Yahoo mail as somehow it was automatically transferred to Techy-9. At the moment I am a little wary about this company but will be much happier when I get back my £150 and will acknowledge that it was a rogue technician.
Just don't download anything that says it will clean your Mac.
