I received a notification message on my browser tonight apparently saying I need to call 1800 508 252 to fix a virus. I tried to close the message but it kept reoccurring. So I gave the number a go, and it sounded like a reliable source. They did a search on my laptop and found that there was over 400 Trojans and 14 hackers... And my email is hacked. She also said that the hackers stopped many programs running and it was only a matter of time before they completely turn off my laptop. So I need help. Not sure if what she's saying is true, but I would love your advice!
I bought this laptop a few months ago but I didn't get around to re-installing antivirus software. I don't mind factory resetting the laptop since I just copied everything to my hard drive. Any option is fine, as long as it all gets fixed! I'm typing this through my phone at the moment. Please, please reply as soon as you can.
