Major web browsers have removed support for FTP (File Transfer Protocol) for security reasons. This includes:
FileZilla is an open-source option available for FTP servers.
The No More Ransom project website has free decryption tools for many known ransomware types. Avast Decryption Tools, Trend Micro Decryptor, and ID Ransomware are other websites that can help victims of ramsomware. A list of antivirus software providers for Windows may be found here.
The United States Cybersecurity & Infrastructure Security Agency (CISA) has a site with tips on how to prevent ransomware attacks.
Google Chrome comes with Chrome Cleanup, a web browser feature that creates alerts when it detects unwanted software and allows the user to remove the software and return Chrome to its default settings.
If a decryption tool is not found, one option is to replace the hard drive and operating system and save the locked drive offline. A decryption tool for the ransomware strain may become available months later to free the data at that point.
Opera is currently testing its free VPN service in its Opera for Android browser. Free VPN is currently available for the Windows and Mac desktop versions of Opera for extra privacy when browsing the web, and it is especially useful when connected to public Wi-Fi networks.
Microsoft announced that their Edge browser will be changed to become Chromium compatible (and behave more like Google Chrome) in order to standardize web development. The Edge development team has shared more details on the transition to the open source Chromium project at its Developer Blog site and GitHub pages.
Update: Edge browser is now Chromium compatible in 2021.
Most major web browsers such as Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge and Internet Explorer should already be using TLS 1.2 (Transport Layer Security protocol) if the latest versions are installed.
Windows devices can be updated by selecting Control Panel -> Network and Internet -> Internet Options. Under the Advanced tab, TLS 1.0 and TLS 1.1 should be unchecked.
To verify if your browser meets TLS 1.2 security requirements, you can access these links: www.ssllabs.com/ssltest/viewMyClient.html and www.howsmyssl.com
Websites and servers that have not recently been updated may still be running TLS versions 1.0 and 1.1, so web browsers and apps may display error messages or block access to them.
TLS 1.3 is currently the latest version, which was published by the Internet Engineering Task Force (IETF) in August 2018.
