Firefox 43.0 was released recently, so it is possible that the Kaspersky database has not been properly updated. Your technical details provided to us show that you are running the latest version of Firefox, so you should not be at any security risk.

Please advise the Kaspersky technical support team about this issue so that they can look into a potential patch of the issue.

Wesley- I appreciate your timely response. I should add that I did speak with a Kaspersky technical support team member who stated Kaspersky does not provide a fix (to include a patch) for vulnerable applications. To my knowledge, Kaspersky normally would provide details about the vulnerable application but in this instance no such information is available or provided because the link simply goes to Kaspersky's SecureList where it states "Description for "10723" not found ..."

Since my earlier correspondence, I spoke with my relative who is experiencing the same problem. However, Kaspersky's technical support has asked that he send a zip folder containing the content of his Mozilla Firefox folder located under his Program Files (x86) folder for evaluation.

Oddly enough, I also did an update of Mozilla Firefox on my Dell Inspiron 15R laptop (Windows 7) earlier today as well and no such problem exists after doing a vulnerability scan.

As long as you downloaded your copy of Firefox from the official Mozilla website, there should be no vulnerabilities. If you would like to ensure that you do not have any infections in your installation, you can run a scan using one of these free programs that will run alongside your antivirus:

• Microsoft Safety Scanner
• MalwareBytes' Anti-Malware
• Anti-Rootkit Utility - TDSSKiller
• AdwCleaner (for more info, see this alternate AdwCleaner download page)
• Hitman Pro
• ESET Online Scanner

Please let us know the results of this scan.

To be clear, I originally downloaded/installed the latest version of Firefox (v43.0) directly from the Mozilla website. However, as per the attached screenshot, this application continues to show vulnerability after numerous attempts to find a resolution. The actions that I have taken thus far to resolve this issue are as follows:

1. Ran MalwareBytes Anti-Malware - (No threats identified)
2. Ran AdwCleaner - (Deleted registry key & misc. folders w/ files)
3. Ran TDSSKiller Anti-Rootkit Utility (No threats found out of 525 objects)
4. Ran Kaspersky Manual Rootkit Scan via batch file - (No threats detected out of 3537 objects ... See http://forum.kaspersky.com/index.php?showtopic=320014&h1=text+.bat)
5. Cleaned the Temp Directory

Still seeking a resolution ... Thanks you!

Did you make sure that Kaspersky is updated to the latest versions of all databases?

Can you post the detailed report?

Yes, Kaspersky has been updated to the latest versions of all databases.

Please see the attached screenshots of the Firefox properties as well as the vulnerability scan report, including specific details.

Does Kaspersky still report a problem with Firefox?

You can try (another) clean reinstall and delete the Firefox program folder before installing.

• (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
• (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"

You can find the full version of the current Firefox release (43.0.1) in all languages and all operating systems here:

• https://www.mozilla.org/en-US/firefox/all/

Sorry about the belated response, but other issues took precedence over the last few days.

Anyway, I used Revo Uninstaller Pro to completely remove Firefox and then - as per Cor-el's recommendation above - the current 64-bit version of Firefox (v43.0.2) was reinstalled on the system. Unfortunately, a follow-on Kaspersky vulnerability scan continues to show Mozilla Firefox as a vulnerable application.
