Beware of the FAKE Quickheal Inc PayPal Invoice Email Scam
Written by: Thomas Orsolya
Published on:
Scam emails pretending to be from the antivirus software company Quickheal Inc are targeting users with fake PayPal invoices. The scam emails come from unfamiliar addresses and include false claims about your supposed support renewal payment being due. If you call the number in the scam emails, malicious actors posing as Quickheal Inc support agents aim to steal your personal and financial information. This ongoing scam has cost many victims – don’t let it happen to you.
Overview of the Quickheal Inc Invoice Scam
This prolific scam starts with an email that appears to come from the legitimate antivirus software company Quickheal Inc. However, the messages actually originate from fraudulent addresses like support@quickhealinc.com, billing@quickhealinco.com, or quickheal-service@consultant.com.
The scam email claims you have an unpaid renewal invoice from Quickheal Inc for antivirus software support or protection services. Some examples show invoices for ridiculous amounts like $386 or even $500 to create urgency. The emails often include an attached fake PDF invoice as proof of the renewal payment needed.
If you call the phone number provided in the email, scammers posing as Quickheal Inc support agents will answer. They confirm some personal details to build trust, then request remote access to your computer to supposedly process a refund or cancellation. In reality, the scammers aim to steal financial information, install malware, and drain your bank accounts once granted access.
The urgent tone, poor grammar, suspicious attachments, and unfamiliar email addresses are red flags that signal this Quickheal Inc invoice is not legitimate. But the scam takes advantage of Quickheal’s reputation as a security company to convince victims the emails are real. Don’t let this scam make you the next victim.
How the Quickheal Inc PayPal Invoice Scam Works
Here is a step-by-step explanation of how the Quickheal Inc PayPal invoice phishing scam unfolds:
1. You receive an email claiming to be from Quickheal Inc.
The scam email is sent from an address like support@quickhealinc.com or billing@quickhealinco.com. The subject line often says “Unpaid Invoice” or “Renewal Payment Due.”
2. The email includes an urgent unpaid invoice for Quickheal Inc services.
The attached PDF invoice is fake. But it shows an amount like $386 or $500 with PayPal as the processor to create urgency. The invoice lists made up renewal dates, customer IDs, license details, and more.
3. If you call the number, scammers pretend to be Quickheal Inc support.
When victims call the number in the email, the scammers confirm some personal or account details to build trust in the call.
4. The scammers claim they see suspicious activity on your computer.
The fake support agent will say they’ve detected malware, viruses, or unauthorized logins on your device. This sets up the next phase.
5. They offer to remove the threats if you provide remote access.
The scammers say they need temporary remote access to your computer to scan, fix issues, and process your refund/cancellation for the fake invoice.
6. If you allow access, the scammers can install malware, steal info, and drain accounts.
Once granted access, the attackers can:
Record passwords, financial details, and personal data
Install malware and spyware for continued access
Drain bank accounts and steal money
Hold your device for ransom
7. You’ve now become a victim of fraud.
In the end, falling for this scam can lead to identity theft, financial account infiltration, and stolen funds. Quickheal Inc had nothing to do with the fake invoices and calls.
What to Do If You Fell for the Quickheal Inc Scam
If you called the number in a Quickheal Inc scam email and granted the scammers remote access, take these steps right away:
Disconnect your device from the internet. This stops the attacker’s access immediately.
Run anti-malware and antivirus scans. Check for and remove any malware, spyware, or viruses.
Change all account passwords. Update passwords for online banking, PayPal, email, and any accounts storing financial or personal data. Enable two-factor authentication when possible.
Contact your bank and credit card companies. Alert them to possible fraud on your accounts. Closely monitor statements and transactions.
Place fraud alerts. Contact Equifax, Experian and TransUnion to place fraud alerts on your credit. This blocks new lines of credit being opened.
File a complaint with the FTC. Report the scam to the Federal Trade Commission at ReportFraud.ftc.gov. Provide details on the scam email, sender address, phone number, and more.
Warn others. Share your experience publicly or on social media to spread awareness about the Quickheal Inc invoice phishing scam. Your story could prevent others from being victimized.
Being proactive after an attack is critical to help limit damages and prevent further misuse of your personal data. Don’t let embarrassment or fear stop you from taking action to protect yourself after falling for this scam.

10 Rules to Avoid Online Scams
Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.
Stop and verify before you click, log in, download, or pay.
Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).
If you already clicked: close the page, do not enter passwords, and run a malware scan.
Keep your operating system, browser, and apps updated.
Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.
If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.
Use layered protection: antivirus plus an ad blocker.
Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.
If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.
Install apps, software, and extensions only from official sources.
Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.
If you already installed something suspicious: uninstall it, restart, and scan again.
Treat links and attachments as untrusted by default.
Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.
If you entered credentials: change the password immediately and enable 2FA.
Shop safely: research the store, then pay with protection.
Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.
If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.
Crypto rule: never pay a “fee” to withdraw or recover money.
Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.
If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.
Secure your accounts with unique passwords and 2FA (start with email).
Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.
If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.
Back up important files and keep one backup offline.
Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.
If you suspect infection: do not connect backup drives until the system is clean.
If you think you are a victim: stop losses, document evidence, and escalate fast.
Move quickly. Speed matters for disputes, account recovery, and limiting damage.
Stop payments and contact: do not send more money or respond to the scammer.
Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
Scan your device: remove suspicious apps or extensions, then run a full malware scan.
Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.
These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.
