800-303-8110

This is the number listed to call when redirected via virus to the scam site "tech01geek.com/ms/" it wants you to call "MICROSOFT WINDOWS LIVE SUPPORT" for help which is probalby just a means to get further information from you. It is not affiliated with Microsoft or any reputable support.

Just called this number secondary to a pop up stating I was hacked and at risk for identity theft. I called them and the man I spoke with (accent, possibly Indian) expressed I needed to pay $200 for a anti hacking download. He was wanting to get remote access to my computer and stated I could not use the computer or the hackers would have access to anything on it. I had immediately turned off my computer when I saw the message. This felt like a scam so I told him I would need to call back.

You should probably run your anti-virus and anti-malware - looks like your computer may be infected.  However - no reputable company - including Microsoft and its partners - will call you unless you've called them first.  More here:

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.

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 website to install software that will let them access your computer to fix it. Once you do this, your computer and your personal information is 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)

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.

A "Virus Alert" appeared on my computer.  It said to call 1-800-303-8110 which was the Microsoft Help desk.  I called and the person said I had been hacked by Russians.  Then he wanted to sell me a security software so I hung up and ran my antivirus program.

A relative was having problems with he PC and was attempting to get in touch with Norton to get some assurance there were no viruses, etc. on her computer. She had Norton 360 installed and functioning.  An internet search for "Norton" returned this 800 number.  A tech named "Martin Dawson" answered and attempted to gain access to her computer to verify virus and related issues.  When he was unable to access he advised her computer was fine, but  she was the victim of "viral hacking" and Norton 360 would not combat this.  Martin offered her a "special deal" - Norton Internet Security lifetime offer for $300. Unfortunately, the relative called me before buying and asked me to verify before making the buy.
I called the 800 number, challenged the rep and asked to speak to a supervisor.  "Jackson" viewed the results of Martin's call in a log, which aligned with my relative's story - all sounding official and compliant.  He stayed with the deficient Norton 360 story with the need to buy Internet Security.  The $300 offer was a generous special Martin had given due the hacking concern for convenience.
I contacted the real Norton Support which confirmed Norton 360 was fine as-is and protecting the PC.  The 800 number had no connection with them.
