• Clean the keyboard and mouse. Remove dust, dirt, and debris from the surfaces you touch most, using suitable cleaning materials.
• Wipe the monitor and external surfaces. Never apply liquid directly to electronic components.
• Keep vents clear. Make sure air vents and cooling areas aren't blocked by dust, furniture, or objects. Good airflow helps prevent excessive heat.

• Check available storage. Make sure your main drive has enough free space for normal system and app activity.
• Remove unnecessary files. Review temporary files, old downloads, and duplicates.
• Review unused applications. Remove software you no longer need, especially programs you don't recognize.
• Note unusual slowdowns. Is it suddenly slower, freezing, crashing, or taking forever to start? Write it down. It's a clue worth following.

• Confirm your antivirus or Virus Guard is active. It should be running with no unresolved warnings.
• Check for security updates. Make sure your protection has current threat definitions.
• Run a scan. Use a scheduled or manual scan, following your security software's recommendations.
• Review suspicious files and downloads. If something is unfamiliar, don't open it to find out what it is.

• Check operating system updates, especially security updates.
• Update your web browser. An outdated browser can cause security and compatibility problems.
• Update key apps, such as office software, PDF readers, and communication tools.
• Restart when required. If an update needs a restart, do it rather than postponing it again.

This is the section people skip, and the one they regret skipping.

• Check that important files are backed up. Include work documents, business files, and anything essential.
• Confirm recent backups actually worked. A configured backup system doesn't guarantee a successful backup. Check that recent ones completed.
• Review your important folders. Make sure new or recently changed files are saved where your backup can find them.

• Review browser extensions. Remove any you don't recognize or no longer need.
• Look for unusual account activity. Unexpected sign-ins or password-reset emails deserve prompt attention.
• Use multi-factor authentication where available. It protects important accounts even if a password is compromised.
• Be careful with links and attachments. Even a message that looks like it's from someone you know can be unsafe.

Something failed? Here's what to do

Don't panic. A failed check isn't proof of infection or damage.

Make it a weekly habit

The checklist only works if you actually do it. A few ways to make it stick:

• Pick one day and keep it. Routine beats good intentions.
• Work through one section at a time so it never feels like a big task.
• For teams: share the checklist with employees. A consistent routine can reduce avoidable computer problems and build everyday security awareness.

How Virus Guard supports everyday protection

Keeping your antivirus or endpoint protection active is a core part of a secure computer. A suitable solution can help detect malicious files and other threats and provide ongoing protection against common security risks.

Still, security tools work best when they're maintained. Regular updates and scans are part of the routine, not a replacement for it.
