1. Use Security Software
Make sure that a reliable antivirus and firewall are turned on to block any potential threats in the future. Set scheduled scans to keep your system continuously secure.
2. Regularly Check Account Statements
Keep an eye on your bank and credit card statements for any unauthorized transactions. Promptly report any fraudulent activity to your financial institution.
Reinstalling Your Operating System: A Last Resort
If, after following all these steps, you still suspect that your laptop is not completely secure, a full operating system reinstallation may be necessary:
1. Backup Your Important Files
Before taking drastic action, be sure to back up essential data. Use external storage or cloud services to save your files. Be cautious and scan these files for malware before backing them up.
