How to safeguard your older PC

Whether you have an older PC lying around your home or you’re considering buying a used/refurbished PC to save money, there’s nothing wrong with doing this. However, there is one problem you should know about: older computers can be more vulnerable to security threats because they haven’t been given updates in a long time. This not only puts you at risk, it can also make your computer run more slowly. Additionally, if you sell or giveaway an older PC without properly clearing out the system, you never know who could still have access to your files and data.

So, how can you make sure your old PCs – whatever you intend on doing with them – are up to date and don’t pose a risk for you? Let’s find out.

What are the risks associated with using an older PC?

Using an older computer poses a number of security risks based primarily on the fact that the software it’s running is outdated. This includes operating systems and applications that may lack essential security patches. These systems are more susceptible to known vulnerabilities and exploits, increasing the likelihood of malware infections and other potential cyberattacks.

Additionally, older hardware may have inherent vulnerabilities that simply can’t be mitigated through any type of software update, and compatibility issues with modern security software that you could potentially install to mitigate this could only exacerbate the problem. Essentially, as newer systems receive more attention and updates, older computers become increasingly vulnerable and less capable of defending against evolving threats.

How to keep an older computer secure

Knowing the security risks that come with older computers doesn’t mean you should always just resort to buying a new computer. But, it is important to take security seriously and ensure that old computer is as secure as any new one.

Here are five steps you can take to keep your system safe:

1) Regular updates: Ensure your operating system, antivirus and firewall programs are up to date. This helps patch security vulnerabilities and guards against known threats.

2) Consider upgrading your OS: Unsupported operating systems like Windows XP are particularly vulnerable. Consider upgrading to a newer OS or switching to a free alternative like Linux to access current security updates and support.

3) Use secure browsing alternatives: Opt for safe and private browsers instead of Internet Explorer, which has officially been retired and is out of support.

4) Have good antivirus software: The best way to protect yourself from clicking malicious links that install malware that may get access to your private information on your PC is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android & iOS devices.

5) Maintain best practices: Adopt good habits like shutting down your computer regularly, uninstalling unused programs and backing up your files to mitigate the risk of data loss due to hardware failure or cyberattacks.

How to speed up an old computer

Free up disk space: Remove unnecessary software and delete unused files to free up disk space, which can help improve overall performance. Tools like “Disk Cleanup” on Windows can be very helpful for this.

Defragment your hard drive: Regularly defragmenting your hard drive organizes data more efficiently, making it easier for your computer to access and improving its speed. This process is automated on modern versions of Windows (7 and later), so there’s no need to do it manually. However, if you’re using an older version, you can use the built-in defragmentation tool.

Consider adding more memory: Increasing the amount of RAM in your computer can significantly enhance its multitasking capabilities and overall speed. Research the type of RAM your computer uses and consider adding more if needed. If you’re not comfortable with this, a professional or a tech-savvy friend can help.

Update your drivers: Ensure your device drivers are up to date to prevent compatibility issues and optimize performance. Many drivers update automatically, but it’s wise to check periodically. You can also visit the manufacturer’s website for instructions.

Manage start-up processes: Control which programs launch during startup to reduce boot time and improve performance. Disable unnecessary startup processes using guides tailored to your operating system. On Windows, you can use the “Task Manager” to disable start-up programs.

What to do if you sell an old computer?

Before selling or getting rid of an older computer, it’s crucial to take steps to protect your personal information and ensure the next user doesn’t have access to your data. Here’s what you should do:

Back up your data: First, make sure to back up any important files, documents, photos or other data you want to keep. You can transfer these files to an external hard drive, cloud storage or another computer.

Securely erase data: Simply deleting files or formatting the hard drive may not completely erase your data, as it can still be recovered using specialized software. Consider using a data erasure tool or disk-wiping software to securely erase the entire hard drive, making it nearly impossible for anyone to retrieve your personal information. Check out our top data recovery software solutions by clicking here.

Sign out of accounts: If your computer is linked to any online accounts or services like your email, social media accounts or software subscriptions, make sure to log out of these accounts before resetting the computer. This prevents the next user from accessing your accounts unintentionally.

Remove external devices: Don’t forget to remove any external devices connected to the computer, such as USB drives, external hard drives or printers, as they may contain personal data as well.

Perform a factory reset: Performing a factory reset is not only essential to wipe all your personal data from the computer and restore it to its original settings, it’s often the easiest and quickest option instead of manually doing all the steps above. This process removes all files, applications and user accounts, essentially giving the next user a clean slate. Be sure to follow the specific instructions for your computer model to initiate a factory reset properly, and make sure to check that it worked and none of your files are still there!

By following these steps, you can ensure that your personal information is safeguarded and that the next user receives a clean and secure computer.

Kurt’s key takeaways

Computers that are regularly updated tend to have less security risk. But that doesn’t mean you need to trade in your perfectly good PC for a new one. It just means you have to pay extra attention and take a few additional steps to keep your PC secure. Doing these steps can also ensure your older computer isn’t slowing down either.

Stranger Things 5’s first trailer promises an epic showdown

Stranger Things 5’s first trailer promises an epic showdown

It’s been a long time coming, but we finally have a real look at the end of Stranger Things. Netflix just released the first teaser trailer for the show’s fifth season, which will also be its last when it starts streaming later this year. As was alluded to in the finale of season 4, the new trailer — which, despite being called a teaser, clocks in at nearly three minutes long — is focused on the major showdown with Vecna that will presumably end the string of supernatural bad luck in Hawkins, Indiana for good.

Here’s the official setup for the finale, according to Netflix:

The fall of 1987. Hawkins is scarred by the opening of the Rifts, and our heroes are united by a single goal: find and kill Vecna. But he has vanished — his whereabouts and plans unknown. Complicating their mission, the government has placed the town under military quarantine and intensified its hunt for Eleven, forcing her back into hiding. As the anniversary of Will’s disappearance approaches, so does a heavy, familiar dread. The final battle is looming — and with it, a darkness more powerful and more deadly than anything they’ve faced before. To end this nightmare, they’ll need everyone — the full party — standing together, one last time.

Landline identity theft leads to major bank fraud

NEWYou can now listen to Fox News articles!

Landline identity theft is an emerging threat that gives scammers backdoor access to your accounts. 

An outdated phone number, especially a forgotten landline, can help them bypass security and drain your savings. 

Here’s how it happens and how to stop it.

IS YOUR PHONE HACKED? HOW TO TELL AND WHAT TO DO

How forgotten landline identity theft drained a bank account

Richard from Reno, Nevada, shared a troubling story. His friend lost money to scammers because their old landline number was still linked to a bank account.

It started with a credit alert asking whether the friend had opened a new card. They said no and thought the issue was resolved.

But soon after, they couldn’t access their bank or investment accounts. Despite having transaction alerts enabled, the money was already gone.

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

The scammer didn’t hack a password. Instead, they used a security loophole, an outdated landline still listed on file.

“My friend had an old but active landline linked to their bank account,” Richard said. “The thief convinced the phone company to port the number to a mobile device. Then they used it to intercept security codes and drain the account.”

The scammer requested a password reset. The bank sent a verification code to the old number, now controlled by the scammer. That code let them change the login, lock the victim out, and move the funds.

Credit monitoring caught the new credit inquiry but failed to detect the fraud inside the existing accounts. By the time access was restored, the money had disappeared.

Why landline identity theft is so easy to pull off

This scam highlights how identity thieves evolve. They don’t always need advanced tools. Sometimes, they just use the details you’ve forgotten.

The role of number porting

The attacker used number porting, a process meant to help people keep their number when switching carriers. It’s legitimate, until scammers exploit it.

In this case, the thief pretended to be the victim and asked the phone company to transfer the landline number to a mobile device. Once the number was active, they received calls and texts, including two-factor authentication (2FA) codes.

How old contact info creates new risks

Many people forget to update recovery settings after creating an account. But an outdated phone number or email can still receive security codes. If a scammer gains control of those recovery tools, your accounts are wide open.

The overlooked weaknesses that made this attack work

Even small gaps in your security settings can lead to big problems. These were the key vulnerabilities in this case:

Old phone numbers stay linked too long

Scammers can hijack even inactive numbers through porting. If those numbers still connect to your bank or email, they become an easy target.

Credit monitoring can miss real-time fraud

Tools that monitor new credit accounts won’t always detect unauthorized transactions in your existing bank or investment accounts.

Weak 2FA setups can be hijacked

2FA is helpful, but only when the linked phone number or email is secure. If a scammer controls that method, they can bypass your protections.

How to prevent landline identity theft

You can’t stop scammers from trying, but you can make it much harder for them to succeed. Use these steps to reduce your risk.

1. Audit your account recovery options: Check your recovery settings on every important account. Delete old phone numbers or backup emails. Keep only active, secure options on file.

2. Use an authenticator app: Authenticator apps like Google Authenticator, Authy, or Microsoft Authenticator generate one-time login codes on your device. This is safer than relying on text messages, which scammers can intercept.

3. Freeze number porting with your carrier: Contact your phone provider and ask about port-out protection. This feature blocks scammers from transferring your number without extra identity verification like a PIN or in-person request.

4. Remove your info from data broker sites: Scammers gather personal details like old numbers from public broker listings. Use a data removal service to erase this info from the web. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com/Delete.

5. Monitor your bank activity directly: Set up alerts through your bank for every transaction. Log in regularly, even if you haven’t received any warnings, to catch fraud faster.

6. Use a password manager: A strong, unique password protects each account. A tool like a password manager creates and stores complex passwords for you. It also tracks password health and alerts you to possible breaches. Get more details about my best expert-reviewed Password Managers of 2025 at Cyberguy.com/Passwords.

7. Consider full identity theft protection: Even with strong passwords and 2FA, your personal info can still be exposed. An identity theft protection service offers dark web monitoring, account alerts, and some offer up to $1 million in identity theft insurance. See my tips and best picks on how to protect yourself from identity theft at Cyberguy.com/IdentityTheft.

Kurt’s key takeaways

Landline identity theft shows that forgotten account settings can turn into serious threats. Take a few minutes to review your recovery options. Switch to authenticator apps. Set up port-out protection. And don’t rely on credit monitoring alone, it can’t catch everything. These simple steps can help you stay ahead of evolving scams and protect your most important accounts.

Analogue’s 4K N64 has been delayed again, but only by a month

The Analogue 3D has been hit with another delay, but should still be launching this summer. In an update on its preorder website, Analogue explained that it’s modern take on the Nintendo 64 “is now shipping in late August 2025,” after previously aiming for July. The company said in a separate statement that the decision was made due to the ever-changing situation around US tariffs.

“Following last week’s sudden tariff changes, Analogue 3D will now begin shipping next month,” the company explained in a post on X. “We’re absorbing the costs — your preorder price stays the same. No additional charges. Late August, the wait ends: reviews go live with everything we’ve been saving for this moment.”

Like its previous hardware, the $249.99 Analogue 3D is a modern console designed to play old games, in this case N64 cartridges. The new console can upscale classic games to 4K and includes multiple display modes to mimic the look and feel of a CRT display, and the company says that it supports 100 percent of N64 cartridges. It was originally planned for a launch in 2024, but has been hit with multiple delays since it was initially announced.
