Key Takeaways
If your computer is running slow or acting strangely, a virus might be the cause
Most viruses can be removed using antivirus scans and safe mode
Some malware hides or blocks your antivirus, and that’s when you call for help
Cloud Atlas offers fast, local virus removal across New Jersey
Watch the video tutorial to follow along step-by-step
Step 1: Disconnect From the Internet
As soon as you suspect a virus:
Turn off Wi-FI
Unplug ethernet
Don’t connect USB drives or cloud sync apps
This stops the virus from spreading or leaking your data.
If you’re already working with Cloud Atlas remote IT support, we’ll walk you through this step over the phone before connecting.
Step 2: Boot Into Safe Mode
Safe Mode loads your system with the bare minimum it needs to run.
It prevents the virus from activating fully.
To boot into Safe Mode:
Windows 10/11
Hold Shift while clicking Restart
Go to Troubleshoot > Advanced Options > Startup Settings
Press F4 for Safe Mode
macOS
Hold Shift while booting your Mac
Now your system will run without most third-party apps — making it easier to find and delete the virus.
Step 3: Delete Temporary Files
Temporary files can hold malware or help it reload after restarts.
To clean them up:
Windows
Open Disk Cleanup (search in Start menu)
Select temporary files, downloads, recycle bin
Click “OK” to delete
Mac
Use Finder to access ~/Library/Caches
Delete unnecessary folders inside
This can speed up the virus scan and remove infected temp files.
Step 4: Run a Full Antivirus Scan
Now run your antivirus program.
Use a trusted tool like:
Windows Defender (built-in)
Malwarebytes
Bitdefender
Avast or AVG
Be sure to run a full scan, not a quick one.
If your antivirus won’t open — or it closes during the scan — you may be dealing with a more advanced virus.
In that case, it’s time to contact a pro.
Reach out to Cloud Atlas virus removal experts for help.
Step 5: Delete or Quarantine the Virus
Once the scan is complete:
Let the software quarantine infected files
Don’t ignore flagged results
Reboot your system once the cleanup is done
If files were deleted that you still need, check the quarantine folder to restore safe ones — but only if you’re sure they’re not malicious.
Step 6: Install Updates and Security Patches
Viruses often spread through outdated software.
To stay protected:
Run Windows or macOS updates
Update your browser (Chrome, Firefox, Edge)
Update antivirus software
Turn on automatic updates if available
Cloud Atlas offers patch management as part of our NJ support plans — we keep your system secure automatically.
Step 7: Reset Your Web Browser (Optional)
Some viruses hijack your browser homepage or install toolbars.
Here’s how to clean it up:
Chrome
Go to Settings > Reset and clean up
Choose “Restore settings to original defaults”
Firefox
Type about:support in the address bar
Click “Refresh Firefox”
Edge
Go to Settings > Reset settings > “Restore settings to their default values”
After this step, your browser will run clean, without shady toolbars or redirect links.
Step 8: Restore Clean Backups (If Needed)
If the virus corrupted or deleted files, restore them from a clean backup.
Use:
Cloud backups (like OneDrive or Google Drive)
External hard drive backups
Managed backups from your IT provider
No backup?
Cloud Atlas offers cloud backup for NJ businesses and home users — set it up before the next problem hits.
