Although, this is a far more complicated process which requires your attention and specific IT skills. For this reason, experts from LosVirus.es suggest you stick with automatic adware elimination method and achieve your goal safely and effectively.
Questions about Call Microsoft Support
Is 'Call Microsoft Support' a real message from Microsoft?
No, "Call Microsoft Support" is a fake pop-up scam, not a genuine Microsoft message. The alert falsely claims to detect Zeus virus or critical system errors, displaying messages like "Don't Restart Your Computer—Windows Detected ZEUS Virus." It provides a fake phone number (+1-888-969-0708) and error codes.
Legitimate Microsoft never displays full-screen pop-ups demanding calls. Microsoft warnings appear in Settings or Windows Defender with professional formatting. Scammers designed these pop-ups to look convincing by using official-looking graphics and urgent language, but the format and demands reveal its fraudulent nature.
What should I do if I see this pop-up?
Do NOT call the provided phone number. Close the pop-up by clicking the X or closing your browser tab immediately. This is a phishing attempt using fake urgency.
The "error code" displayed means nothing—the infection claim is false. Your computer is almost certainly not infected with Zeus virus.
The scammers' goal is gaining remote access to steal information or money. If you accidentally called, hang up immediately and don't follow their instructions.
Do not allow remote access or payment requests. Run legitimate antimalware software to clean any adware causing the pop-ups. Never trust pop-up warnings; legitimate security alerts come from your installed security software.
Is my computer infected with the Zeus virus if I see this alert?
No, your computer is not infected with Zeus virus. "Call Microsoft Support" is a phishing scam using fake urgency to trick users into calling fraudsters. The alert is entirely fabricated to manipulate emotions.
Microsoft doesn't detect viruses through pop-ups and never requests phone calls to support numbers. If Zeus virus actually existed on your system (which it doesn't from this alert), Windows Defender would show genuine alerts in Settings, not full-screen pop-ups.
This scam's sole purpose is financial fraud through remote access fees or tech support charges. Ignore the alert completely and close it immediately.
Should I call the phone number shown in the alert?
Absolutely not. The provided phone number (+1-888-969-0708) connects to fraud scammers, not Microsoft support. Calling results in connecting with criminals intending to steal money or gain computer access.
Common tactics include requesting remote access via TeamViewer or AnyDesk, claiming you need expensive software, or demanding payment for "virus removal." Once scammers gain access, they may install malware, steal banking information, or encrypt files.
Even if you don't pay, your system faces serious compromise. Legitimate Microsoft support never requires phone calls from random pop-ups. Real support initiates contact only when you actively request it.
How do I remove 'Call Microsoft Support' pop-ups?
First, close the pop-up without clicking any links. The pop-ups come from adware or PUP (potentially unwanted program) on your system. Download reputable antimalware software like Microsoft Defender (already installed on Windows) and run a full system scan.
The scan detects and removes the adware causing pop-ups. Restart your computer and scan again to ensure complete removal. Check browser extensions for suspicious add-ons and remove them.
Clear browser cache, cookies, and history. To prevent future pop-ups, avoid suspicious websites and be cautious with freeware installations. The pop-ups may reappear if adware completely removed—persistence confirms earlier detection's success.
Is 'Call Microsoft Support' a virus or just adware?
"Call Microsoft Support" pop-ups typically come from adware or browser hijackers rather than viruses. The scam operates as a PUP (potentially unwanted program) delivering intrusive pop-ups rather than malware stealing files.
However, adware can coexist with actual malware. Running antimalware scans is essential to check for additional threats beyond the pop-up provider. Some variants may bundle keyloggers or spyware alongside pop-ups.
While the pop-ups themselves represent social engineering rather than technical infection, the underlying adware poses risks through persistence and potential malware delivery. Professional security scanning eliminates both the pop-ups and any accompanying threats.
Can scammers actually help if I call them?
No, scammers cannot help with any legitimate computer problems. They're criminals with no technical expertise or authorization from Microsoft.
Their sole goal is stealing money or gaining unauthorized computer access. Common deceptions include:
- claiming to detect nonexistent viruses
- requesting remote access to show fake "scans," demanding payment for removal
- upgrading to expensive "premium support,"
- requesting credit card information
Once connected, scammers are persistent and manipulative, using social engineering to maintain the call and push payments. Legitimate tech support never involves pop-ups demanding calls. If you need genuine help, contact Microsoft directly through official channels, not numbers from pop-ups.
How do I prevent 'Call Microsoft Support' scams in the future?
Avoid visiting suspicious or secondary websites that distribute scareware. Download software only from official sources. When installing freeware, use Advanced installation settings and deselect optional add-ons like browser extensions and PUPs.
Keep all software updated, including Windows and browsers, to patch security vulnerabilities. Install reliable antimalware software with real-time protection.
Be skeptical of unsolicited pop-ups claiming system problems—legitimate warnings come from your installed security software, not random websites. Never grant remote access to unknown individuals.
Use pop-up blockers in browsers. Educate yourself about common scams so you recognize tactics immediately. If warnings appear unusual or pressuring, close them rather than interacting.
What personal information might scammers ask for?
Scammers typically request remote access first (via TeamViewer, AnyDesk, etc.) to show fake system scans convincing you of infection. After establishing access, they request credit card information for payment. They may ask for banking credentials or passwords, claiming these authenticate account access.
Some request email and addresses for alleged "warranty registration." Never provide any personal information to pop-up callers. Legitimate Microsoft support never requests remote access from initial contact or personal financial information through phone calls.
If you've already called and provided information, contact your bank and credit card companies immediately. Change important passwords, monitor accounts for fraud, and consider credit monitoring services.
Will Fortect remove Call Microsoft Support?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Call Microsoft Support, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
