Cybersecurity Tips.
Step-by-Step Guide to Managing Your Data and Securing Your PC or Laptop
1. Regular Disk Cleanup (Every 7 to 14 Days)
Your computer stores temporary files that can slow down performance. Performing a disk cleanup will free up space and improve speed.
How to Perform Disk Cleanup (Windows)
1. Click the Start button and type "Disk Cleanup" in the search bar.
2. Select the drive you want to clean (usually C:) and click OK.
3. Check the boxes for Temporary files, Recycle Bin, and System Files (if needed).
4. Click OK, then Delete Files.
How to Perform Disk Cleanup (Mac)
1. Click the Apple menu and go to About This Mac > Storage > Manage.
2. Review recommended actions, such as emptying the trash and removing unused files.
3. Use a tool like CleanMyMac for deeper cleaning.
2. Backup Your Data to the Cloud (At Least Weekly)
Backing up your files ensures you don’t lose important documents, photos, or work data if your computer crashes or gets stolen.
Backing Up to OneDrive (Windows Users)
1. Open OneDrive and sign in with your Microsoft account.
2. Drag and drop files into your OneDrive folder.
3. Turn on Auto Backup by clicking OneDrive Settings > Backup > Manage Backup.
4. Select the folders you want to back up and click Start Backup.
Backing Up to Google Drive
1. Open Google Drive in your browser or install the Google Drive for Desktop app.
2. Sign in with your Google account.

3. Keep Your Programs and Software Updated
Software updates often include security patches that protect you from viruses and hackers.

2. Click Check for Updates.
3. Install any available updates.
Updating macOS
1. Click the Apple menu and go to System Settings > Software Update.

Updating Programs & Antivirus
• Open each program and check for updates in the Help or Settings menu.
• Use Windows Defender or install an antivirus like Bitdefender or Kaspersky to keep your system secure.
4. Be Aware of Phishing Emails
Phishing emails try to trick you into giving away sensitive information by pretending to be from reputable companies like banks, SARS, or major retailers.
How to Spot a Phishing Email
• The sender’s email address looks suspicious (e.g., @gmail.com instead of @absa.co.za).
• The email asks for personal or financial information.
• It contains urgent or threatening language like "Your account will be suspended!".
• The email includes links that look legitimate but lead to fake websites.
How to Protect Yourself
• Never click links in emails from unknown senders.
• Hover over links to see the actual web address before clicking.
• Verify with the company by calling their official customer service number.
• Mark suspicious emails as spam and delete them.
5. Handling Emails with Invoices and Bank Account Details
Cybercriminals often send fraudulent invoices with fake bank account details. Before making any payments, always verify the bank account details directly with your client.
How to Verify Bank Account Details
• Call the client directly and read the bank account number to their financial contact before making a payment.
• Request proof of bank account details from the client’s bank, such as an official stamped letter or bank confirmation document.
• Use WhatsApp or a known secure messaging platform to confirm the bank account details directly with the client.
• Never pay into a bank account received via email without verifying it first. Cybercriminals can intercept emails and change banking details.
Final Recommendations
✅ Perform a disk cleanup every 7 to 14 days.
✅ Back up important files to the cloud weekly.
✅ Update Windows, macOS, and software regularly.
✅ Stay alert to phishing emails and never share sensitive information.
✅ Always verify bank account details before making payments.
By following these steps, you will keep your PC or laptop running smoothly and protect your personal data from cyber threats.
