Malware is created by a wide range of people such as vandals, swindlers, blackmailers, and other criminals. While the overwhelming majority of malicious programs are designed to make money illegally, the motives behind creating malware can range widely from pranks and activism, to cyber theft, espionage, and other serious crimes. As the legitimate use of computers, mobile devices, and the Internet has grown, so have the opportunities for disreputable people to benefit by creating these harmful computer viruses, worms , Trojans , and other forms of malware.
How can you stay safe? Back up your data. If you can restore your data from backup files, malicious encryption will have limited effect. Do not click email attachments. Patch and update software regularly. Software manufacturers continually update their products to close vulnerabilities and increase security.

Install security software. Make sure you have a reputable security product installed and kept updated. You can easily download Avast security products to get real-time protection against ransomware and other malicious attacks.

These ads come in the form of e-mails and pop-ups on your computer. If enough computers get infected, they can earn money from all the ads displayed. The more ads they send out, the more chances they have of getting people to buy something or visit the advertiser.
