A document arrives by email, and the attachment looks like an image. You open it expecting paperwork, then another download appears.
If NexusRAT has appeared in a security alert, the details of that download matter. Start with what happened, not what the attachment seemed to be.

Overview
This NexusRAT campaign targets Windows banking activity
NexusRAT is a remote-access banking threat associated with fake login overlays and keystroke capture. An overlay places a deceptive window over something you recognize.
The Windows delivery chain examined here starts with an emailed SVG attachment. A linked page supplies a ZIP archive containing a VBS script.
Executing that script is a materially different exposure from receiving the message. The infection account does not establish that merely viewing an inbox installs NexusRAT.
Keep this Windows campaign separate from Android banking malware also called Nexus. Similar names do not justify Android permission instructions for a Windows script infection.
A genuine banking address does not protect an infected desktop
The reported malware watches for targeted banking activity and displays a convincing substitute interface. The person can be looking toward their bank while typing into an attacker’s window.
That distinction explains why checking a web address alone is insufficient after malware runs. The problem can be on the computer, not the bank’s server.
The useful questions are practical:
- Did the attachment launch a page or download another file?
- Was the archive extracted, and was its script executed?
- Which financial accounts were used afterward?
- Did a security tool identify a file, process, or execution chain?
Cleanup and financial protection need separate attention
A scanner can quarantine detected components. It cannot cancel a bank transfer, retrieve copied credentials, or decide whether a particular login was authorized.
Contact the bank promptly if the script ran and banking credentials were subsequently entered. Make that contact from another device or a trusted telephone.
How to Remove NexusRAT From Windows
For a work or school computer, contact its IT or security team before installing tools or restarting. Its investigation may need evidence from the running system.
If remote access is suspected, disconnect Wi-Fi or Ethernet and stop using this PC for sensitive accounts. Arrange trusted downloads and updates before proceeding with cleanup.
Start with Malwarebytes. HitmanPro and ESET are optional second opinions for unresolved findings or continuing symptoms. Run one scanner at a time.
- STEP 1: Use RKill only if malware blocks your scanner
- STEP 2: Scan and quarantine threats with Malwarebytes
- STEP 3: Optional: Check unresolved threats with HitmanPro
- STEP 4: Optional: Run a second-opinion scan with ESET
Step 1: Use RKill only if malware blocks your scanner
RKill attempts to stop known malware processes so your security software can run. It does not remove the infection.
Use it only on a personal Windows PC when malware is blocking your scanner. Otherwise, skip directly to Malwarebytes.

Run RKill.
Open your Downloads folder and double-click iExplore.exe. Allow the program time to finish checking for processes that interfere with cleanup.

When the black window closes, a log opens. Keep the log, do not restart yet, and continue directly to Malwarebytes.
Step 2: Scan and quarantine threats with Malwarebytes
Malwarebytes for Windows can scan for malware and quarantine detected threats. Use the free Custom Scan below; a paid plan is not required for this cleanup.
Download Malwarebytes

-
Wait for installation to finish.
-
If the Welcome to Malwarebytes screen appears, click Get started and follow the remaining prompts.
-
On the final screen, click Open Malwarebytes to launch the program.
-
Choose the scan type and optional rootkit check
On the Scanner tile, click the three dots, choose Advanced Scan, then Custom Scan.
Expand the folder selector and select the C:\ system drive. Include any other drive where the suspicious files were stored.
If Scan for rootkits is available, you can enable it. This setting is unavailable on Windows ARM devices; leave Windows security protections enabled.
Review how potentially unwanted programs and modifications will be handled. Keep detection enabled rather than automatically ignoring these items.
Start the Scan
Click Start Custom Scan. Allow Malwarebytes to update its detection information if prompted.
-
Wait for the Scan to Finish
Wait for the Custom Scan to finish. The time required depends on the selected locations and the amount of data.
-
Quarantine the Detected Threats
When the scan finishes, review the detections and keep the threats you want removed selected. Click Quarantine.
If a detection is unclear, save the report and ask for help before excluding or restoring it.

Wait while Malwarebytes quarantines the selected items. Do not restore a file merely because an unfamiliar name appears in the results.

-
Restart Your Computer
If Malwarebytes asks for a restart, save your work and click Yes. After signing back in, reopen Malwarebytes and check the report for unresolved detections.

Step 3: Optional: Check unresolved threats with HitmanPro
HitmanPro is a second-opinion scanner for Windows. It examines suspicious files using cloud analysis, including SophosLabs. An internet connection is needed for that check.
Scanning is free. Removing detections requires an eligible one-time 30-day trial or a paid license.
A computer that already used its trial may not qualify again. You do not have to buy HitmanPro to follow the Malwarebytes cleanup above.

-
Click “Activate Free License”
If this computer qualifies, click Activate free license and follow the activation prompts.
If no trial is available, use an existing license or save the report for assistance. Do not assume a purchase is necessary to continue cleanup.

After removal, review the summary and click Next. Choose Reboot if requested, or Close if no restart is needed.
If detections return or the original symptoms persist, keep the reports and ask for help. A clean scan cannot rule out every threat.
Step 4: Optional: Run a second-opinion scan with ESET
ESET Online Scanner is a free second-opinion scanner for Windows. Use it if you need another check after cleanup, rather than running several scanners together.
-
Download ESET Online Scanner

Technical Details Worth Knowing
An image attachment invites another action
SVG is an image format, but an SVG document can also contain links and active content. An image-like appearance does not make every interaction harmless.
In this delivery chain, the attachment contains an image that leads onward when clicked. The apparent document is a bridge to a different resource.
A browser page delivers a compressed archive
The attachment’s link opens a page using a blob URL. Browsers use blob URLs for legitimate locally created content too, so that prefix alone is not a verdict.
Here, the important behavior is the next download: a ZIP archive carrying a VBS file. The expected document has become something Windows can execute.
Running the VBS file crosses the execution boundary
A VBS file contains instructions for Windows Script Host. It is not simply another page of an invoice, even when its displayed filename suggests paperwork.
The malware imitates a targeted bank’s interface
The described toolkit includes a collection of banking-interface images. Browser activity helps it choose when to display a matching overlay.
Captured information creates an account problem elsewhere
Keystroke capture can expose information entered through the imitation. Stolen credentials are useful to an attacker even after the infected computer has been disconnected.
What Your Bank Needs to Know
Tell the fraud team that Windows malware may have captured your login. Describe the script execution and subsequent banking activity rather than reporting only a suspicious email.
Explain whether you entered a password, approved an authentication request, or initiated any transfer. Include the approximate times, account involved, and transaction reference where available.
Ask the bank to review access and unauthorized payments. It may need to revoke sessions, replace credentials, restrict transactions, or handle an account-specific recovery process.
Never move funds to a supposedly safe account on a caller’s instructions. Independently call the number on your bank card or use its established application.
If a payment is unfamiliar, report it immediately. Do not wait for a complete malware diagnosis before asking whether a transfer can be stopped or recalled.
What to Do If You Ran the Attachment’s Script
Stop sensitive activity on that PC. Disconnect its network connection and avoid signing into anything else while the compromise is being assessed.
Notify the financial institution. Use a separate trusted device and explain possible banking-credential capture, including any transactions you do not recognize.
Secure the recovery account. Change exposed email credentials, inspect recovery details, and end unfamiliar sessions before relying on that inbox for other resets.
Document the chain. Retain the original email, download names, security reports, and relevant timestamps. Do not forward an executable attachment to friends for testing.
Arrange malware removal. Follow the Windows procedure above for a personal device. An employer’s computer should go through its security team instead.
Watch for follow-up approaches. A caller claiming to reverse the incident should not receive remote access, bank codes, or an advance recovery fee.
After Quarantine: Check the Banking and Email Accounts
Use a known-good computer to review recent sign-ins, saved beneficiaries, standing instructions, and payment changes. Ask the institution about anything you cannot explain.
Check email forwarding rules and unfamiliar connected applications. An intruder who retains mailbox access can intercept warnings or restart account recovery after a password change.
Keep any bank case number alongside the scan report. Together they connect the device incident with its financial consequences without assuming every later charge is related.
Restore ordinary banking use only when the computer is trustworthy again. A bank’s successful password reset is not a technical clearance for Windows.
Frequently Asked Questions
Is this the same threat as the Android Nexus banking Trojan?
This article addresses the Windows SVG-to-VBS campaign described as NexusRAT. Do not apply its cleanup steps to an Android phone merely because a detection name overlaps.
Can an SVG attachment really lead to malware?
Yes. This case uses an SVG as a route to another page and a malicious download. That does not make every SVG image dangerous.
Am I infected if I only downloaded the ZIP?
A saved archive alone does not establish script execution. Avoid opening it, check existing alerts, and tell a responder exactly which actions you took.
Does the fake banking screen mean my bank was hacked?
No. A local overlay can imitate a bank without compromising its systems. The bank still needs to know that your credentials may have been exposed.
Will removing NexusRAT restore money taken from my account?
Removal addresses detected malware, not payments. Contact the bank’s fraud team separately and follow its process for reporting unauthorized transactions.
Should I erase Windows immediately?
Not without preserving essential files and considering evidence needs. A confirmed compromise may justify rebuilding, but that decision needs a recovery plan.
The Bottom Line
Do not run a script supplied through an unexpected document email. NexusRAT’s Windows delivery chain turns that extra download into a banking-account risk.
If it already ran, isolate the PC, contact your bank through a trusted route, and complete device cleanup alongside account and session recovery.
