Other Ways to Protect Yourself
First you need to ensure that you never open an email or download anything that is sent to you by an unknown person/source. It is recommended that you always check the name of the file in the email before opening it on your computer or web browser. If you use Gmail, it scans every attachment that is delivered to your Inbox and blocks the infected file if it’s already in your Inbox. Although opening an email is safe, it is still recommended that you avoid opening emails that have attachments or links from unknown senders.
Second, ensure that you update your Windows and your antivirus program. It is very important to perform a regular system scan to check if your computer is infected or not. If you are not sure of the PDF files that you have downloaded, you can scan them with Virustotal to make sure they are virus-free .
As hackers are finding new ways to attack you, you should take all the precautionary steps to make sure your system does not get infected. On the other hand, the antivirus companies are also on the verge of releasing new virus definitions every day. So, it is highly recommended that you install good antivirus software such as Kaspersky or BitDefender, and set them to update definitions automatically.
