I'm sorry about the issue. This looks like a scam. Usually, any company that tries to contact you first is scamming you. You should always ignore any phone call or email message or popup window that you do not know or that you are not expecting.
What is the security package that you just purchased?
What is the company name that contacted you?
Is there any issue with your computer?
Please reply at the box below. Thank you.
Also, do you have Windows XP, Vista, or 7 or 8 or 10?
And was there any issue with your computer previously that you needed help from that company?
