A Step-By-Step Guide to Handling Malware, and How Cybersecurity Services Prevent It
When people hear the term “digital age,” they think of speed, convenience, and infinite access to information in the palm of their hand. However, the digital age is also rife with threats and hazards that can take over a device in a single misguided click.
Most notably, malware can wreak havoc on your computer and compromise your personal and professional data, leading to serious consequences like identity theft, financial loss, and IT disasters.
Naturally, this begs the question, “How do I know if my computer has been infected by malware?”
After defining what malware is and the most common signs that it has infected your device, we’ll provide a step-by-step guide to troubleshooting and resolving malware issues. As a preventative measure, we’ll also highlight some of the main benefits of cybersecurity services as they pertain to malware and other viruses.
What Is Malware?
Malware, short for malicious software, refers to any type of software designed to harm, exploit, or otherwise compromise your computer and its data. Malware comes in various forms, including viruses, spyware, ransomware, worms, and trojans. Hackers use malware to gain unauthorized access to systems, steal sensitive information, and disrupt computer operations.
Malware is distributed through several channels, such as infected email attachments, malicious downloads, suspicious websites, or even through seemingly legitimate software that carries hidden threats.
There are two highly effective ways of preventing malware. The first is partnering with a cybersecurity service provider that establishes a robust system of protection. The second is conducting employee cybersecurity awareness training, because human error causes more than 90% of data breaches.
Common Signs Your Computer Is Infected By Malware
Malware infections often cause noticeable issues with your computer’s performance and security. If you’re unsure whether your computer has been compromised, look for these signs:
- Your computer is running unusually slow, freezing, or frequently crashing.
- You’re experiencing a barrage of pop-up ads, even when you’re not browsing the web.
- Your web browser keeps redirecting you to strange or unknown websites
- Your homepage suddenly changes without your consent.
- You’re finding software or apps on your computer that you didn’t install.
- You’re seeing strange error messages.
- Your applications are unexpectedly closing.
- Your antivirus or security software has been disabled without your knowledge.
- You’re experiencing unexplained network activity or data usage.
- You can’t access your files or network.
Resolving Malware Without Professional Cybersecurity Services: A Step-by-Step Guide
If you suspect that your computer is infected by malware and don’t have a cybersecurity service provider, promptly address it to minimize the damage.
Step 1: Delete the Malware-Infected App
Most malware is delivered by installing apps. If you notice signs of malware after installing a particular app, immediately remove it from your device. Simply trashing it isn’t enough. Empty your trash and perform a system search for the deleted app to confirm it’s gone.
Step 2: Disconnect From the Internet
If you don’t know the source of the malware infection, disconnect your computer from the internet. Malware often communicates with external servers, sending sensitive information or downloading additional harmful files. Disconnecting from the internet helps prevent data theft and further infection.
Step 3: Scan Your Machine Using Basic Cybersecurity Services
All computers have basic cybersecurity services built in. Perform a system scan using your antivirus or anti-malware software. It should be able to detect any malicious code that’s on your machine.
Step 4: Enter Safe Mode
Reboot your computer in safe mode to prevent the malware from loading. Safe mode only allows essential system files to run, making it easier to isolate and remove malware.
Step 5: Delete Temporary Files
While in safe mode, delete temporary files to free up space and potentially remove any malware hidden in these directories. You can use your machine’s built-in disk cleanup tool or a third-party tool to remove temporary files.
Step 6: Check Installed Programs
Go through the list of installed programs on your computer to identify and remove any suspicious or unknown software. Malware often installs unwanted programs that run in the background, so uninstall anything that looks unfamiliar or malicious.
Step 7: Reset Your Web Browser Settings
Random redirects and strange browser toolbars are common signs of malware. If your web browser is being hijacked by malware, reset your browser settings to default. This can remove unwanted extensions and restore normal functionality. Clear your browser cache and cookies to eliminate traces of the infection.
Step 8: Update Your Operating System and Software
Outdated operating systems and software are more vulnerable to malware infections. After the malware has been removed, update your operating system (Windows, macOS, etc.) and any installed software to ensure you’re protected against future threats.
Step 9: Change All Your Passwords
If malware has infected your computer, there’s a chance that your login credentials for email, bank accounts, and social media have been compromised. Change all your passwords as a precaution using strong password best practices.
Step 10: Perform a Factory Reset
A factory reset is highly effective in removing malware but should be reserved as a last resort. Everything, including any malware, will be wiped from your device. This effectively resets your machine to its factory settings, meaning you must reinstall your apps, readjust your personal settings, and retrieve your backup data from the cloud or external hard drive. Although performing a factory reset is inconvenient, it’s the only surefire way to resolve malware if all else fails.
How Cybersecurity Services Prevent Malware
Cybersecurity as a service implements multiple layers of defense across networks, devices, and user activity. Providers of cybersecurity in Kansas City typically install firewalls, antivirus software, and intrusion detection systems to monitor and block potential threats before they can infiltrate a system.
Cybersecurity service providers also ensure that software and operating systems receive regular updates with security patches to close any vulnerabilities that malware might exploit. Finally, cybersecurity service providers can educate users about safe online practices, such as recognizing phishing attempts and avoiding suspicious downloads, further reducing the risk of malware infections.
By continuously monitoring and responding to potential threats, cybersecurity services create a robust defense system that helps prevent malware from compromising sensitive data or disrupting operations. Contact a provider of cybersecurity in Kansas City to learn more about safeguarding your organization against digital threats.
