Malware experts with Microsoft advise against paying the ransom because there is no guarantee the user will regain access to the compromised files. Performing regular backups of your important data has proven to be the most efficient prevention mechanism against ransomware attacks.
Ransom:Win32/Isda – Distribution and Behaviour

Ransomware infections usually use a Trojan to infiltrate the system. This can occur as the user browses corrupted web pages or by downloading malicious attachments to spam emails. Cyber criminals often use institutions or famous brands as a disguise for the malicious payload.
In most cases, the ransom is to be paid in BitCoins or other crypto currency using anonymity networks.
