that some of the adware installed without consent, despite declining all install requests, or used deception to obtain the user's "acceptance" to install. Among the reported effects are: web browser being hijacked, with content, start page and search engines being forcibly changed, popup windows, privacy or spying issues, sudden shutdown and restart events possibly leading to loss of current work. Some of the adware was reported to resist removal or restoration of previous settings, or were said to reinstall after a supposed removal. Also, users reported adware programs to download and install more unwanted software, some causing alerts by security suites, for being malware. The FileZilla webpage offers additional download options without adware installs, but the link to the adware download appears as the primary link, highlighted and marked as "recommended". As of 2016, FileZilla displays ads (called sponsored updates) when starting the application. These ads appear as part of the "Check for updates" dialog. In 2018, a further controversy about FileZilla's use of a bundled adware installer caused concern. Plain text password storage Until version 3.26 FileZilla stored all saved usernames and passwords as plain text, allowing any malware that had gained even limited access to the user's system to read the data. FileZilla author Tim Kosse was reluctant to add encrypted storage. He stated that it gives a false sense of security, since well-crafted malware can include a keylogger that reads the master password used to secure the data. Users have argued that reading the master password to decrypt the encrypted storage is still harder than just reading the unencrypted storage. A fork called FileZilla Secure was started in November 2016 to add encrypted storage. In May 2017, encrypted storage was also added to the main version, 10 years after it was first requested. Kosse maintained that the feature did not really increase security, as long as the operating system is not secure. FileZilla Server FileZilla Server is a sister product to FileZilla Client.
