We've had 10 of these calls today and a few yesterday. A number when straight to answerphone and did not leave a message.
The longest conversation I let the guy show me how many errors there were on my PC event log and then he took me through downloading some remote access software. A number of times I had to correct him as he accent was so bad. He told me my speed was bad - and I explained 450Mb is about right and when I refused to give him the access code the conversation got a bit "fruitier" at his end. He needed to be more emphatic with his "F"'s.
7:40 am - not awake yet - so thanks for that. 8:20 - still not awake but that reminds me to ring openreach. 9:20 I'm ringing from Virgin Media ... <No You're Not> ... <click> 9:40 - my internet speed - we don't have the "Internets" here - <click> 10:00 - please tell me what country you are from, I love your accent, do you need a work visa <click>
The software they are using is called AnyDesk - and it's a great bit of software. We use it every so often to get support from suppliers. And like all these programs you have to give access.
Don't worry about me - I just wasted their time.
In general if someone access your computer using a program like AnyDesk then you do not need to wipe as everything they do is visible. Their next step would probably to take you to a website to download some more advanced software which would ask you for admin permissions ... and then you would have compromised the integrity of the system.
The general rule is that unless you have had 3 attempts at putting in your security code and had to listen to 10 minutes of naff music then it's not a genuine call.
