Avoid opening any spam email attachments
Email box fills up immediately and that is inevitable, but you need to be aware of the dubious content and do not open letters that you have no idea about. Especially when there is an attachment. They might contain cyber threats, such as ransomware, spyware[3] and other malware.
Before opening an email attachment, you need always double-check the information and make sure that you were supposed to get it and it is safe to open. For instance, if you received an information about parcel delivery issues, but you haven't ordered anything, this letter is not for your. Also, if you received an email that asks to print some documents or check invoice information, but you are confused why you were sent this, this letter is not for you too.
Unexpected letters that usually urge to open attached documents most of the time spread malware. So, keep away from them to keep your system virus-free and files secure from encryption.
