A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11An unexpected phone call claiming to be Microsoft Support should be treated as a scam. Microsoft says it does not proactively contact people to provide unsolicited PC or technical support, and genuine Microsoft error or warning messages do not include a phone number to call. Hang up; do not call the number in a pop-up, click a supplied link, install software, or share passwords, verification codes, payment details, or remote access.
If you already interacted with the caller, the right response depends on what happened. Disconnect a remotely accessed computer, change exposed passwords from a clean device, contact financial providers immediately, and report the incident.

The fastest test: Did you request support?
The most useful rule is simple:
If you did not initiate support through an official Microsoft channel, do not treat an incoming call as Microsoft Support.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
A legitimate support interaction may generate follow-up communication after you opened a case. Verify that contact through the original support case or your Microsoft account—not merely because an incoming caller claims to be Microsoft.
#1 Best Overall
- COMPATIBILITY: For traditional analog landline phones and services from providers such as AT&T, Verizon, Frontier Communications, CenturyLink, and Brightspeed. Not compatible with internet-based or digital phone services (VoIP), including Vonage, Ooma, Xfinity Voice, and Quantum Fiber.
- IMPORTANT: The V5000 CPR Call Blocker requires Caller ID service and an analog telephone line. Without Caller ID, incoming numbers cannot be identified or blocked. No mains power required - just plug it into your phone line and use.
- Powerful Blocking, Made Simple: Preloaded with 5,000 verified scam and nuisance numbers, the V5000 starts protecting you right out of the box. And if a new or spoofed number gets through, the large “BLOCK NOW” button makes it easy to instantly block it - up to 1,500 additional numbers at your command.
- Realistic & Reliable Protection: While no device can stop 100% of spam (scammers constantly change numbers), the V5000 gives you the power to shut down repeat offenders quickly and effectively - offering more control than passive filters alone.
- Hassle-Free Design: NO POWER supply needed, NO APP, and NO SUBSCRIPTIONS. The V5000 is easy to install, with a clear screen and loud button click for extra confidence. Designed with seniors in mind, it’s ready to use and simple to maintain. For even stronger protection, you can pair it with your phone provider’s spam filtering service.
This distinction matters because “Microsoft will never contact you” is too broad. The warning applies to unsolicited technical-support contact. Caller ID is not proof: scammers can spoof trusted numbers, including real Microsoft phone numbers.
Red flags that expose the scam
- The caller contacted you without your requesting help.
- They claim Microsoft detected a virus, hack, suspicious activity, license problem, or account breach.
- They create urgency by saying your computer will be blocked, your files deleted, or your account closed.
- They ask you to install AnyDesk, TeamViewer, Quick Assist, or another remote-access tool.
- They request a password, Microsoft Authenticator approval, text-message code, Social Security number, card number, or banking information.
- They demand gift cards, cryptocurrency, a wire transfer, a payment-app transfer, or an unusual “refund” payment.
- They direct you to call a number displayed in a browser pop-up or error message.
- They insist you stay on the line, keep the matter secret, or avoid consulting a family member, bank, or technician.
Microsoft, the Federal Trade Commission, and the FBI identify these tactics as common elements of technical-support scams.
How the “Microsoft” scam works
Cold-call impersonation
The caller may introduce themselves as Microsoft, Windows Security, Microsoft Security, or a “Microsoft partner.” They invent a technical problem and offer to fix it. A real virus or computer problem would not make an unsolicited caller legitimate.
Free tools Windows power users keep installed
One-click scans. No signup required.
Fake browser warning
A malicious or compromised webpage can display a full-screen warning with alarming sounds, repeated dialog boxes, Microsoft branding, and a phone number. The number belongs to the scammer. It is not evidence that Microsoft detected anything.
If the pop-up will not close, do not call it. Use the browser’s normal close controls or restart the computer. Microsoft recommends updating security software and running a scan afterward. Microsoft’s security guidance provides additional steps.
Fake support websites and search advertisements
Scammers create lookalike Microsoft support pages or buy advertisements that appear when someone searches for help. A familiar logo, domain design, or search position does not authenticate the site. Navigate independently to support.microsoft.com instead of using a phone number, link, or email address supplied by someone else.
Rank #2
- How it Works: SPAM identified calls are instantly blocked automatically. Preferred Calls Ring through like normal with Caller ID displayed. Your phones connected to the TEL port Won't Ring on Blocked Calls. Create your own Invited or Allowed Family (White List) and block All other callers.

Works with Any Analog Corded, Cordless Phone or Fax System on any telephone service. Large Back-Lighted Display. Got questions? Call the number on the front screen of the ProSeries 3.
- Works with all USA phone companies: AT&T, Cox, Spectrum, CenturyLink, Cable Modems, DSL, FIOS, or Digital Services from VoIP Telcos like [V] from Verizon, Ooma Telo, Ooma Basic, Vonage, Magic Jack etc. Also, works in Mexico, Canada, Brazil, European Union (ETSI), Australia, Singapore and others with North American standardized phone lines.
- Allow any blocked caller to ring through like normal with the Green Invite Button. Double Tap the Green Button to add VIP callers shown in Call History. Note: Caller ID Name and Number Service from your phone company is required for this model to work automatically.
Fake subscription-renewal or refund notices
An email, text, or pop-up may claim that a Microsoft, Norton, McAfee, or other security subscription was renewed. It tells you to call to cancel or obtain a refund. Once you call, the scammer may request remote access, banking details, or repayment of a supposedly excessive refund. The FTC warns that this is a common route into a technical-support or refund scam.

A message or caller may claim that your Microsoft account was hacked or that an unusual sign-in requires immediate verification. The goal may be to steal your password or one-time authentication code rather than control your computer.
What to do while the scammer is on the phone
You can say:
“I do not accept unsolicited technical support. I will contact Microsoft through its official website.”
Then hang up. Do not argue, call back, or follow instructions to “prove” the infection.
- Never give a caller a password or “test” code.
- Never read back a text-message code.
- Never approve an unexpected Microsoft Authenticator prompt.
- Do not open Command Prompt, PowerShell, Event Viewer, Registry Editor, or system logs because a stranger tells you to.
- Do not trust a caller because they know your name, approximate location, computer type, email address, or other personal details.
- Do not rely on Caller ID.
Block the number if useful, but remember that scammers can call again from a different number.

- This is the latest version Telephone Call Blocker with hidden or unavailable call numbers can be blocked. And there is no fees to use it; Please keep the manual for future use.
- Block up to 4000 individual phone numbers, including incoming and outgoing calls , prefixes and up to 10 digit area codes.
- One-touch to Block: Locate a number and then press Block to add it to the blacklist.Better set the call blocker in series ( one end of it connected to your phone and another end to the PSTN telephone line); Though it can also be set up parallel, but not compatible with some phone systems.

- Battery free: It is line powered, no need battery. And it works with almost all single line telephones. If you find some numbers are blocked but you never mean to, then press Block and check your blacklist, then delete those numbers which like area codes or prefix numbers.
Depending on permissions, session length, and what was open, the scammer may be able to:
- View files, browser tabs, saved information, and account activity.
- Search for passwords, tax documents, identity documents, banking details, or cryptocurrency wallets.
- Install malware, ransomware, unwanted software, or another persistent remote-access tool.
- Manipulate normal Windows utilities and present ordinary system information as “proof” of infection.
- Access email or financial accounts that were already signed in.
Remote access creates serious risk, but it does not prove that malware was installed or that the scammer saw every file. Treat the incident as potentially compromised until you have secured the accounts and examined the computer.
Choose the recovery steps that match what happened
If you only answered the phone
If you did not provide sensitive information, click anything, install software, or follow instructions, hang up, block the number if desired, and report the attempt. You generally do not need to reset your computer solely because you answered a call. Be alert for follow-up calls, texts, and emails.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If you clicked a link or visited a suspicious page
- Close the browser tab or window. If it will not close normally, use standard operating-system controls or restart the computer.
- Do not call the number displayed on the page.
- Do not download or install anything the page offered.
- Update your security software and run a full scan.
- Review browser extensions and installed applications for unfamiliar items.
- If you entered a password or other credentials, change them from a known-clean device.
A scan is important, but it is not an absolute guarantee that every compromise has been found.
If remote-access software was installed or used
- Disconnect the computer from the internet. Turn off Wi-Fi or unplug Ethernet.
- End the remote session if it is still active.
- Using another trusted device, change the password for your Microsoft account and primary email account.
- Change every other password exposed on the computer, especially banking, payment, shopping, cloud-storage, work, and school accounts. Do not reuse the old password.
- Enable multifactor authentication where available.
- Review security pages for unfamiliar sessions, devices, recovery addresses, forwarding rules, app permissions, and newly added authentication methods.
- Run a full scan with current security software.
- Document the remote tool’s name and any suspicious files, messages, or account changes before removing software.
- If you cannot establish that the computer is safe, use a reputable technician you find independently or consider a clean reset or reinstallation.
- Monitor email, financial, and other sensitive accounts for unauthorized activity.
Uninstalling AnyDesk, TeamViewer, Quick Assist, or another remote-access program may stop that particular tool, but it does not prove that the scammer did not install something else, copy information, or change an account.
If you gave away a password or verification code
Change the exposed password immediately from a clean device, then change it anywhere else you reused it. Prioritize:

If you gave financial or payment information
- Credit or debit card: call the issuer immediately, dispute unauthorized charges, and ask whether the card should be canceled and replaced.
- Bank transfer or wire: contact the bank or transfer provider immediately and request a recall or fraud review.
- Payment app: report the transaction to the app and to the linked bank or card issuer.
- Gift card: contact the gift-card company immediately, keep the card and receipt, and report the fraud.
- Cryptocurrency: contact the exchange or wallet provider, preserve transaction records, and report the incident. Recovery is uncertain.
- Cash or mailed payment: contact local law enforcement and the relevant payment or delivery provider.
Do not keep talking to the scammer because they promise a refund. Contact the payment provider directly. Recovery is not guaranteed, and additional contact often produces another demand.
If you disclosed identity information
If you provided a Social Security number, date of birth, address, identity-document details, or financial-account information:
- Contact affected financial institutions.
- Review bank and credit-card statements.
- Consider placing a credit freeze or fraud alert with the major U.S. credit bureaus.
- Use the FTC’s identity-theft resources for next steps.
- Watch for follow-up impersonation attempts.
Someone who promises to recover your lost money for an upfront fee may be running a recovery scam. Do not pay an unsolicited “investigator,” “lawyer,” or “cybersecurity expert,” especially by gift card, cryptocurrency, or wire.

- REDUCE UNWANTED CALLS & TAKE BACK CONTROL – The CPR V100K helps reduce unwanted spam, scam and robocalls on your landline. Known nuisance numbers in the preloaded database are blocked automatically, while new unwanted callers can be blocked at the touch of a button.
- 100,000 KNOWN NUISANCE NUMBERS PRELOADED – Includes a large database of known nuisance numbers for immediate protection. The database contains reported nuisance numbers from across the USA and is not a list of 100,000 numbers specific to your local area.
- BLOCK NEW CALLERS WITH ONE TOUCH – Scam callers frequently change or spoof their phone numbers, so no call blocker can stop every unwanted call automatically. When a new unwanted number gets through, simply press the large red BLOCK NOW button to prevent repeat calls from that number. Store up to 10,000 additional numbers.
- SIMPLE TO USE – NO APP OR SUBSCRIPTION – Connect the V100K to your compatible landline and start taking control of unwanted calls. No app, Wi-Fi, monthly subscription or external power supply required. The large display and tactile BLOCK NOW button make it particularly easy to use.
- IMPORTANT COMPATIBILITY INFORMATION – Requires an active Caller ID service. Designed for compatible traditional analog landline services. Not compatible with many internet-based or digital VoIP telephone services. Please check your telephone service before ordering.
- Recent sign-in activity.
- Devices and active sessions.
- Recovery email addresses and phone numbers.
- Forwarding rules and mailbox permissions.
- Connected applications and app permissions.
- Authentication methods and unexpected Authenticator approvals.
Use a unique password and multifactor authentication. On Windows, update the operating system and security software, then run a full scan. Microsoft Edge’s Defender SmartScreen can block some known malicious support-scam sites, but it cannot prevent every phone-based social-engineering scam.
If a remote session occurred and suspicious behavior continues, a clean reset or professional examination may be safer than repeatedly uninstalling individual programs. Choose a technician independently; never use one recommended by the scammer.
Where to report the scam
Microsoft
Submit a report through Microsoft’s technical-support scam reporting form. Do not include sensitive information such as your Social Security number, date of birth, financial-account numbers, card numbers, or medical information.
United States agencies
- FTC: ReportFraud.ftc.gov. Reports help identify patterns and build cases.
- FBI Internet Crime Complaint Center (IC3), especially when the incident involved substantial loss, remote computer access, identity information, or another serious cybercrime.
You can also contact your bank, card issuer, payment app, gift-card issuer, or cryptocurrency exchange. Notify an employer or school if its account was involved, and contact local law enforcement where appropriate.
Preserve evidence: the phone number and Caller ID, emails and headers, websites, screenshots, dates and times, remote-tool names, receipts, transaction IDs, and messages.
How to get legitimate Microsoft help
Open a new browser window and navigate to Microsoft’s official support site yourself. Do not use a number from an unsolicited call, pop-up, email, text, search advertisement, or lookalike website. If you recently opened a Microsoft support case, verify any follow-up through the original case or your account.
Microsoft Defender and Windows Security can help update protections and scan a device, but they cannot undo stolen passwords, reverse payments, or guarantee that a remotely accessed computer is clean. If professional help is needed, independently verify the provider, request a written scope and price, and reject anyone demanding gift cards, cryptocurrency, immediate payment, or unexplained remote access.
Helping an older relative or family member
Start with reassurance rather than blame. Ask exactly what was shared or installed, disconnect a remotely accessed computer, and help contact the bank or card issuer before discussing recovery with the scammer. Preserve evidence and work through the account and reporting steps above. A calm checklist is more useful than telling someone simply to “run antivirus.”
