There is no silver bullet that is going to protect a computer from getting hit with malware like ransom-ware. There is no substitute for being suspicious of every e-mail and every web site. If something doesn’t seem right, it probably isn’t. Never open a link in an e-mail or visit an untrusted web site. Have a physically separate firewall that is running threat management software, like a SonicWall, to look for threats before they can touch your computer. Have current anti-virus software, like Symantec, with current virus definition files. Use a cloud based spam filter service, like TnT’s SpamSoap, to catch suspicious e-mails before they reach your computer. Make sure your computer is currently patched to close security holes. Leave as many security controls active as you can stand to block malicious software from running. Follow all of these tips and the risk of getting ransom-ware will be greatly reduced.
