Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteRun a scan in Windows Security, then check its results in Protection history. If you still have credible reason to suspect a remote access trojan (RAT), use Microsoft Defender Offline for a deeper check. A clean scan is useful evidence, but it does not prove that a computer is free of unauthorized access.
What can—and cannot—tell you a computer has a RAT
A RAT is a type of trojan that can let an attacker control a computer remotely. Trojans may also record keystrokes or browsing activity and send information such as passwords or browsing history. These are possible capabilities, not proof that a particular symptom or program is caused by a RAT. Microsoft notes that trojans can imitate legitimate applications, including by using the same file names: Microsoft’s overview of trojan malware.
Possible malware clues include unusually slow performance, reduced battery life, increased data use, unexpected pop-ups, browser redirects, crashes, or security tools that stop working. None is specific to RATs, and each can have causes unrelated to malware. Microsoft cautions that similar symptoms can result from hardware or software problems: Microsoft’s malware and virus removal guidance.
Run a scan with Windows Security
- Open Windows Security and select Virus & threat protection.
- Select Quick scan and let it finish. This is a sensible first check when you suspect malware.
- If you remain concerned, select Scan options, choose Full scan, and start the scan. It checks more of the computer while Windows is running.
- When a scan has finished, open Protection history to review detections and actions taken. Microsoft’s instructions for scan choices are at Windows Security: stay protected.
Windows labels and available options can vary with Windows version, security-provider configuration, and organizational policy. If a scan reports a threat, use Protection history to see what Windows detected and what action it took; do not assume an item was removed unless the recorded action says so.

When to use Microsoft Defender Offline
If the concern remains after an in-Windows scan, Microsoft Defender Offline can scan after restarting into a separate environment. This can make it harder for persistent malware to hide while Windows is running. Save open work first: the PC restarts during the scan.
- Open Windows Security > Virus & threat protection > Scan options.
- Select Microsoft Defender Offline scan, then choose Scan now.
- Allow the PC to restart and complete the scan. After Windows starts again, open Protection history to review the result.
Some device configurations may prevent the scan from running. Microsoft’s technical guidance lists requirements including an enabled Windows Recovery Environment and appropriate Defender configuration; a BitLocker-protected PC may ask for its recovery key after restart. Check Microsoft Defender Offline technical guidance for supported platforms and prerequisites.

How to interpret the result
A detection is a reason to follow the action shown in Protection history and investigate further if the activity or access was unexpected. A clean result means the scan did not report a threat; it is not a forensic verdict that rules out every RAT or unauthorized access. The cited consumer guidance does not establish that any one scan guarantees a computer is clean.
Remote-access software is not automatically malicious. People and organizations use such tools for support and administration, and attackers may abuse the same tools. Do not remove a program just because its name suggests remote access. First determine whether you or your organization installed it and whether its use is authorized. CISA’s Guide to Securing Remote Access Software, published June 6, 2023, advises organizations to inventory approved tools and look for abnormal use, including remote-management software running as a portable executable. Legitimate tools can blend into normal activity and may not trigger antivirus or endpoint defenses.

What to do if you see credible unauthorized access
- Stop using the potentially affected computer for sensitive work. Do not use it to enter passwords or handle other sensitive information while the concern is unresolved.
- If it is a work or organization-managed PC, contact IT or security promptly. Follow their instructions rather than trying to investigate or remove tools yourself.
- For organizational incidents, isolation and investigation may be needed. CISA’s advisory for a specific organizational threat incident recommends isolating affected systems and reviewing relevant logs and artifacts; qualified incident-response support may be appropriate depending on the incident: CISA’s incident advisory. This is escalation guidance for organizational compromise, not a universal household procedure.
If you are a home user and have credible evidence of unauthorized control, avoid treating repeated scans or deleting a remote-access program as a complete investigation. Use a trusted, unaffected device to seek qualified help if needed.
