Protect Your Data From Ransomware With These 5 Steps. Ransomware encrypts your computer data, and demands a ransom for the key to decrypt. It is a nasty exploit; but, there are steps you can take to lessen the likelihood of getting hit. First, use Windows Defender or some other competent Antivirus, and Antispyware tool. Set it to work in real time. Second, make a backup of your essential files on a regular basis. Hook up a USB high capacity drive, and leave it plugged in. Then, image the drive and save your essential files on a daily basis. I use Goodsync to save my essential files to a MicroSD card in my computer on a daily basis. Then, if I have to reinstall Windows 10 to eliminate a ransomware demand, I can reload the data from the MicroSD. Third, use a mail client that has a strong filtering client. GMail catches a lot of phishing and nasty email automatically, and puts it in a Spam folder. You can check the folder periodically to spot misfiltered email. But, better safe than sorry. There are other things you can do in this article. Be careful out there.
