There are so many dangers online these days that we can't be completely protected from them all. However, there are some steps we can take to increase the security of your systems .
1. Check if you are part of a Botnet
First, use an antivirus program to scan computer and detect any malware.
If the program you are using stops during a scan, you may have been infected by Emotet. In this case, you may need to run your computer in safe mode and try the scan again.
Change your email password to a more complex one. Avoid opening emails from senders you don't recognize. If you receive emails with links or attachments, don't interact with them. If someone you know sends you a strange email with a link or attachment, confirm that they sent it before opening it.
2. Use this extension to make all your favorite websites more secure
When browsing the web, make sure to visit websites that start with “HTTPS://”. This tells you that the website is transferring data over a secure, encrypted connection. You’ll also see a padlock icon in your browser’s address bar. However, if a website doesn’t start with this, you can use the HTTPS Everywherefor added security.
3. Επιλέξτε ένα φυσικό κλειδί που δεν μπορεί να παραβιαστεί
Security keys are a physical way to verify your identity online. These small USB act as keys to your online accounts and must be plugged into your computer when you log in. YubiKey and Google Titan are two of the most popular security key brands, and they offer products that work with computers and mobile devices.
4. Choose a security key for your bank
Some banks also offer physical security keys, which act as an extra layer of protection for account . Instead of using a code that your bank sends you, you'll use a special device that connects to your banking app. Because not all banks offer physical tokens or keys, contact your bank to determine what security options are available for your account.
5. Check your firewall and router for exposed ports
Your computer's firewall is designed to provide security by preventing intruders from accessing system and network. Even if an intruder knows your computer's location and IP address, they won't be able to get very far if your firewall is configured properly.
To check your computer's firewall:
Open Settings > Update & Security.
Select Windows Security from the left menu.
Select Firewall & Network Protection to open the firewall menu. Your system will tell you whether the firewall is enabled or not. If it is disabled, you can enable it or reset the settings to defaults by clicking Restore firewalls to default.
