HTML/Fifex.A is a Web page that frequently is a component of other threats, such as variants of the Medfos family of browser hijackers. As per usual Web security protocols, malware experts suggest the use of immediate anti-malware scans, whenever your Web browser loads HTML/Fifex.A or appears to be in contact with HTML/Fifex.A. Symptoms of an HTML/Fifex.A attack area are subject to some variation, but HTML/Fifex.A may be used to install new threats, and has had connections with attacks that may make arbitrary files unreadable.

The Browser Threat that Comes Free with a Desktop Corruption Problem

HTML/Fifex.A may refer to various threats formatted as threatening scripted content (in most cases, JavaScript) within a Web page. Different versions of HTML/Fifex.A may be used to install threatening software automatically, promote unwanted programs through fraudulent download links or redirect you to other, corrupted sites. For now, malware experts may associate the most recent attacks involving HTML/Fifex.A pages with outdated JavaScript and Flash installations, which suggests that other threats may be using vulnerabilities in these programs to install HTML/Fifex.A-related software.

However, HTML/Fifex.A isn't encountered solely as a page your browser redirects towards. Malware experts also have identified Trojans using HTML/Fifex.A as part of background processes maintained in Windows. Internet Explorer may be hijacked for this purpose, regardless of whether or not IE is your default browser.

The latter attacks also carry some particularly visible symptoms with them, such as:

  • Your desktop files may be corrupted and rendered unreadable. This attack may include files of multiple formats, including PDF, DOC or DWG. This last file format, exclusive to CAD software, suggests that the associated threats are meant to compromise commercial PCs, in addition to (or instead of) personal systems. In some cases, victims also reported compromised files related to cloud storage services such as Dropbox.
  • Memory processes associated with HTML/Fifex.A also may maintain their persistence and reopen themselves, even after you terminate them with the Windows Task Manager. These visible background processes may be components of spyware attacks, browser hijackers, spambots and a variety of other, relatively unsophisticated (but still harmful) threats.

Turning an HTML/Fifex.A Problem into an Ex-Problem

Payloads delivered by HTML/Fifex.A attacks are far from set in stone, and you should assume the potential worst outcome for any confirmed encounter with this compromised Web page. Anti-malware products should be utilized to remove any threatening software that may be installed through HTML/Fifex.A automatically, and you should assume that personal data on your PC could be at risk. Regular, remote file backups are the most easily implemented way of avoiding any permanent data loss from HTML/Fifex.A-related attacks, and most victims report being unable to repair files corrupted during the course of an infection.

If your PC shows any symptoms of memory process-related issues from an HTML/Fifex.A attack, reboot your PC with Safe Mode or a separate, uninfected hard drive. Only after verifying that all unneeded and potentially threatening processes are no longer active, should you try to scan your PC and remove all threats related to HTML/Fifex.A.

When they appear by themselves, HTML/Fifex.A alerts may be symptoms of singular, coincidental encounters with a corrupted site. However, returning HTML/Fifex.A alerts usually are signs that your PC has been compromised by additional threats. Whatever the circumstances around an HTML/Fifex.A warning message, you should act as if the worst possible payload could be in effect until your security solutions can determine anything else.
