Remote access can be a convenient feature for tech support or working from a distance, but it can also pose serious security risks if unauthorized users gain access to your computer. Detecting remote access in its early stages can help protect your personal information and system integrity. Here’s how you can check if someone is remotely accessing your computer and steps you can take to secure your device.
When these signs appear on your computer, you should consider whether someone is accessing your computer remotely.
If you notice your mouse cursor moving on its own or making selections without your input, this could be a sign of unauthorized remote access.
Programs or files opening randomly could indicate someone controlling your system.
An unexplained increase in network activity, especially when you are not actively using the internet, might suggest remote access software is transmitting data.
Sudden sluggishness or unexpected restarts could be a result of remote interference or the operation of unauthorized software.
On some systems, notifications or logs will show if someone has connected remotely. Review these to check for unfamiliar sessions.
Here are the ways to check if someone is remotely accessing your computer:
The first step to detecting remote access is by reviewing your computer's recent activity. Windows keeps a log of actions, including login attempts, system changes, and file access.
There are several legitimate tools and applications that allow remote access to a computer. However, cybercriminals can install these programs without your knowledge to control your computer remotely. Common examples include TeamViewer, AnyDesk, Chrome Remote Desktop, and LogMeIn.
Windows Firewall is your first line of defense against unauthorized network access. Remote access software, such as Remote Desktop or third-party programs, requires exceptions in the firewall to function properly. If someone has installed a remote access tool on your machine, they may have altered your firewall settings.
Type Windows Defender Firewall with Advanced Security in the Start menu search and press Enter. Look for any inbound and outbound rules that seem unusual or unfamiliar. If there are dubious rules, click on them and choose Disable Rule at the right sidebar.
Cybercriminals often use malware or viruses to gain remote access to your computer without your knowledge. Running a virus scan with built-in tools like Windows Defender can help you detect malicious software that may be enabling remote access.
Go to Settings > Privacy & Security > Windows Security > Virus & Threat Protection. Click on Quick Scan or Full Scan for a more thorough check.
If you’ve discovered that someone is accessing your computer remotely without your permission, it’s crucial to take immediate action to protect your data and security.
The first thing you should do is disconnect your computer from the internet to stop the remote access. This will give you time to diagnose your computer, remove malware, and protect your account.
Use another secure device to change accounts that could be sensitive or critical (such as email, banking, and social media accounts). Use strong, unique passwords for each account.
Use your antivirus or anti-malware software to run a thorough scan of your system. Remove any threats it finds, especially remote access tools or spyware that might have been installed.
To make sure that your computer is free from any traces of hidden malware, you should restore your computer to factory settings. But before that make sure you back up your data.
Remote access can be a serious security threat, but with the right knowledge and tools, you can detect and stop intruders before they cause harm. If you suspect someone is accessing your computer remotely, act quickly to secure your data and prevent any further intrusion.
