It would be better to make arrangements for safeguarding your investments before even making the actual investments. You can use various protection techniques like desktop wallets, hardware wallets and paper wallets. But do not get carried away with the idea that if you use only these methods you are protected. There are some standard procedures you need to follow as the internet is full of scams and counterfeit softwares. Some steps are as follows:

1.  Use a licensed antvirus or antimalware and keep it updated.
2.  After downloading anything please check its threat status on www.virustotal.com.
3.  Make downloads only from trusted sources.
4.  Do not fall for anything that shines or gives you a promising future because we all know since our childhood that "ALL THAT GLITTERS IS NOT GOLD".
5.  Do not open any links or attachments in your emails.
