What is Ransomware and How to protect your PC from it?

Ransomware is a type of dangerous malware intended to kidnap a customer’s PC containing personal, social, and banking details etc. Also known as cryptotrojan or cryptovirus, Ransomware encrypts a customer’s critical data files without his intention and knowledge and demands ransom in lieu of decrypting them.
Ransomware is not a new malware program. In fact, the beast has been around from a long time and has been the hackers' choice for spreading dreadfulness since its emergence. According to Symantec (a security software vendor), three new ransomware variants have appeared so far. This is quite obvious that such cases have progressed in numbers so far. Previously, attackers only targeted businesses but later on included individuals also in their target list.  
A new type of ransomware also came in vogue lately to seize a user’s PC and encode all the files without sending a ransom/payment note. The data kidnappers target the user while he is surfing the Internet to obtain information about malware programs that encode files. They earn money by selling file-decrypting software on the authentic websites.
Modus Operandi – The user suddenly finds its system locked or inaccessible with a pop-up window flashing on the screen, asking him/her to key in a secret code receivable only after making payment to the attacker. The user may also be asked to send a text message (SMS) for making payment and obtaining the code.
Incoming Source – A computer could come in contact with a Ransomware program from an already-infected program, email attachment, or a malicious/compromised website. So, you need to be careful while surfing the Internet or downloading any email attachment. If the website is not a trusted one or email attachment is not from a trusted sender, than it's better not to open it. Similar to other malware programs, ransomware installs itself on the PC and seizes it completely.
How to protect your PC from Ransomware?

 Well, most of the antivirus programs have security definitions that are capable of blocking common ransomware programs. However, users are strongly recommended to keep a good data backup plan, which stores all their files on an online data backup & storage service or a freestanding drive. Moreover, they are required to install stronger antivirus software that updates itself regularly with the latest security definitions. This will help keep such malicious programs at bay in the first place.
***You can also buy McAfee SaaS Endpoint Protection suite, a stronger antivirus protection for your PC.
For businesses, it is recommended that they invest in putting a Linux-based server to use because most of the GPcode programs attack the Windows OSs. Small-sized businesses, which cannot afford to run Linux-based server, are advised to impart proper training to their employees and users on employing secured computing practices. The more familiar they become with such practices, the lesser will be the chances of getting infected with ransomware. These businesses can also opt to use OpenDNS or other similar online services for blocking the access to compromised websites.
