Overview
Expiro is a file infector that spreads itself by infecting executable files on the computer as well as its removable drives and network shares. Prominent on Windows devices, it embeds itself into executables, making it harder for the system to detect it. File infectors, such as Expiro, can be used for multiple purposes, including stealing credit card information, downloading additional malware, and executing DDoS attacks.
Possible symptoms
Expiro malware can target various system components and often exploits operating system vulnerabilities. If you find files with .exe and ivr extensions on your computer, it’s likely your device is infected. Some other possible symptoms include:
- Unusual system behavior. If your system suddenly needs more time to load, freezes during the day, or if you experience crashes, it may be a sign your device has been infected.
- Unwanted browser extensions. Expiro can install browser extensions and change your browser settings.
- Changes in system settings. System changes, especially antivirus configuration, can be a sign of malware, possibly Expiro.
- Pop-up advertisements. If you start seeing pop-ups or your browser redirects you to another website, be aware. Expiro may be trying to get you to visit fake, hacker-controlled websites.
Sources of the infection
Expiro malware employs a diverse array of propagation methods to infiltrate systems and spread its malicious payload. Some recent reports suggest that Expiro is even spread manually using USB drives. Common sources of infection include:
- Malicious websites. Fake company websites, or even real websites, can be used to spread malware and steal credentials.
- Social media. You may often exchange pictures and links with your friends on social media. Pay attention if their behavior changes, like suddenly using a link shortener or sending links without a message — your friend’s account may be compromised
- Phishing. Phishing is one of the most common ways to spread malware.
- Unverified sources. Pirated software often includes different viruses, including Expiro.
Protection
Expiro is an advanced malware targeting personal data and financial information. It’s a good idea to check the website address whenever a website asks you to enter some information. Other ways of protecting yourself against Expiro include:
- Stay cautious with emails and social media messages, especially if they contain links or attachments.
- Set up multi-factor authentication to ensure your accounts stay safe, even if your password is ever exposed.
- Make sure your antivirus is always up-to-date and turned on.
- Set up a firewall to monitor your web traffic.
- Only use official websites to download software and updates.
You can also use NordVPN’s Threat Protection Pro to scan files and URLs for malware before they’re downloaded to your device.
Expiro malware removal
If you experience any of the possible Expiro symptoms, unplug your computer from the internet, restart it in safe mode, and run an antivirus check. It’s also a good idea to use another device to check on your banking accounts and change your passwords. If you’re not experienced with technology, we recommend contacting security professionals.
