888-609-6554

I just tried to log on to yellowpages.com., and a web warning claiming to be Microsoft came up with a warning that my computer was not protected, and to call this number. Has someone hacked my computer?

just wanted to thank yu for confirming what I thought.  yours was the only response when my search only had the ph. num. as a reference.  had same problem; did not respond as they wanted. thank you

probably not.  I just got the message, ran my anti-virus scan and there is no problem.  I am sure it is not Microsoft, but a company wanting you to sign up for their business.

Same scenario as below hijacked my browser that came with a new hp zbook.  the 888-609-6554 number didn't feel right in as much as I had just installed a complete virus package and was about to install MS Office.  I called McAfee who helped remove the locked page and pupups.

I just got a notification to call this # to remove malware...I have real time malware protection with malwarebytes I tried to open to get a scan and it is dissabled along with my virus protection and fire wall...the person answering identified himself as microsoft but when I specifically asked if this was microsoft the line when dead

Cybercriminals don't just send fraudulent email messages and set up fake websites. They might also call you on the telephone and claim to be from Microsoft. They might offer to help solve your computer problems or sell you a software license. Once they have access to your computer, they can do the following:

Trick you into installing malicious software that could capture sensitive data, such as online banking user names and passwords. They might also then charge you to remove this software.

Convince you to visit legitimate websites (like www.ammyy.com) to download software that will allow them to take control of your computer remotely and adjust settings to leave your computer vulnerable.

Request credit card information so they can bill you for phony services.

Direct you to fraudulent websites and ask you to enter credit card and other personal or financial information there.

Neither Microsoft nor our partners make unsolicited phone calls (also known as cold calls) to charge you for computer security or software fixes.

Telephone tech support scams: What you need to know

Cybercriminals often use publicly available phone directories, so they might know your name and other personal information when they call you. They might even guess what operating system you're using.

Once they've gained your trust, they might ask for your user name and password or ask you to go to a legitimate website (such as www.ammyy.com) to install software that will let them access your computer to fix it. Once you do this, your computer and your personal information are vulnerable.

Do not trust unsolicited calls. Do not provide any personal information.

Here are some of the organizations that cybercriminals claim to be from:

Windows Helpdesk

Windows Service Center

Microsoft Tech Support

Microsoft Support

Windows Technical Department Support Group

Microsoft Research and Development Team (Microsoft R & D Team)

Report phone scams

Help Microsoft stop cybercriminals by reporting information about your phone scam.

In the United States, use the FTC Complaint Assistant form.

In Canada, the Canadian Anti-Fraud Centre can provide support.

In the United Kingdom, you can report fraud as well as unsolicited calls.

Whenever you receive a phone call or see a pop-up window on your PC and feel uncertain whether it is from someone at Microsoft, don’t take the risk. Reach out directly to one of our technical support experts dedicated to helping you at the Microsoft Answer Desk. Or you can simply call us at 1-800-426-9400 or one of our customer service phone numbers for people located around the world.

How to protect yourself from telephone tech support scams

If someone claiming to be from Microsoft tech support calls you:

Do not purchase any software or services.

Ask if there is a fee or subscription associated with the "service." If there is, hang up.

Never give control of your computer to a third party unless you can confirm that it is a legitimate representative of a computer support team with whom you are already a customer.

Take the caller's information down and immediately report it to your local authorities.

Never provide your credit card or financial information to someone claiming to be from Microsoft tech support.

What to do if you already gave information to a tech support person

If you think that you might have downloaded malware from a phone tech support scam website or allowed a cybercriminal to access your computer, take these steps:

Change your computer's password, change the password on your main email account, and change the password for any financial accounts, especially your bank and credit card.

Scan your computer with the Microsoft Safety Scanner to find out if you have malware installed on your computer.

Install Microsoft Security Essentials. (Microsoft Security Essentials is a free program. If someone calls you to install this product and then charge you for it, this is also a scam.)

Note: In Windows 8, Windows Defender replaces Microsoft Security Essentials. Windows Defender runs in the background and notifies you when you need to take specific action. However, you can use it anytime to scan for malware if your computer isn’t working properly or you clicked a suspicious link online or in an email message.

Will Microsoft ever call me?

There are some cases where Microsoft will work with your Internet service provider and call you to fix a malware-infected computer—such as during the recent cleanup effort begun in our botnet takedown actions. These calls will be made by someone with whom you can verify you already are a customer. You will never receive a legitimate call from Microsoft or our partners to charge you for computer fixes.

When I tried to open flicker today 1/7/15, it opened a website that said my computer is unprotected and that I should call this number for Microsoft service or gave me several options to purchase a protection service which I don't need because I have up to date McAfee computer protection service. This rogue page will not allow me to navigate away from the page or close the page. I have McAfee and Will attempt to run it now. This is such a scam and a complete waste of my productivity!
