Sorry this post will be long, but I want to give you all the information I can.

 

Problem: I am unable to download files from email attachments or online using Firefox. I am able to download files using Internet Explorer. I was able to download files using Firefox 29.x, but have not been able to with any updates following. I reverted back to 29.x after updating to 30.x assuming that it would correct itself in the next update. However, I updated to 33.x yesterday and have the same problem. Upon running Malwarebytes and SuperAntiSpyware I have numerous tracking cookies that reappear with each scan without surfing the internet (They are usually in a Mozilla/Firefox folder even though I have not opened FF. FF seems to be running really slow since the update also.

 

When trying to download the file FF goes to Not Responding (if left alone it will do it for hours.) Click anywhere on the screen again and it says that FF has stopped responding and ask to "Close program now" or "Wait for program to respond". When you close the program it gives you a progress bar and says searching the internet for a solution. The program then shuts down.

 

Windows 7 Home Premium

Service Pack 1

Intel Core i3-2310M CPU @ 2.10GHz

Ram 4.00 GB

64-bit Operating System

 

Windows updates are all up to date.

 

Currently using Symantec/Norton. I removed AVG and installed Symantec/Norton yesterday morning after discovering that Firefox was not allowing me to download files and began to wonder if there may be a virus that was causing it.

 

I have ran all 3 virus/malware programs. (Numerous tracking cookies reappear)

 

I have cleared, deleted, and changed the download folder for FF.

 

I have cleared all cookies and temp files.

 

I have fully uninstalled FF and reinstalled.

 

I have created a new FF profile.

 

I have tried to download files in FF safemode.

 

I have disabled all extensions and plug-ins. I have also verified that it is running the default theme.

 

Restored FF default settings.

 

I have temporarily disabled Norton to verify that it was not a prolonged scan of the file causing the problem.

Usually when a computer is infected with malware there most likely will be other obvious indications (signs of infection) that something is wrong.

I have ran all 3 virus/malware programs. (Numerous tracking cookies reappear)

Cookies are text string messages given to a Web browser by a Web server. Whenever you visit a web page or navigate different pages with your browser, the web site generates a unique ID number which your browser stores in a text (cookie) file that is sent back to the server each time the browser requests a page from that server. Cookies allow third-party providers such as ad serving networks, spyware or adware providers to track personal information. The main purpose of cookies is to identify users and prepare customized Web pages for them.

  • Persistent cookies have expiration dates set by the Web server when it passes the cookie and are stored on a user's hard drive until they expire or are deleted. These types of cookies are used to store information between visits to a site and collect identifying information about the user such as surfing behavior or preferences for a specific web site.
  • Session cookies (transient or Non-persistent cookies) cookies are not saved to the hard drive, do not collect any information and have no set expiration date. They are used to temporarily hold information in the form of a session identification stored in memory as you browse web pages. These types of cookies are cached only while a user is visiting the Web server issuing the session cookie and are deleted from the cache when the user closes the session.

Cookies can be categorized as:

  • Trusted cookies are from sites you trust, use often, and want to be able to identify and personalize content for you.
  • Nuisance cookies are from those sites you do not recognize or often use but somehow it's put a cookie on your machine.
  • Bad cookies (i.e. persistent cookies, long term and third party tracking cookies) are those that can be linked to an ad company or something that tracks your movements across the web.

The type of persistent cookie that is a cause for some concern are "tracking cookies" because they can be considered a privacy risk. These types of cookies are used to track your Web browsing habits...your movement from site to site. Ad companies use them to record your activity on all sites where they have placed ads. They can keep count of how many times you visited a web page, store your username and password so you don't have to log in and retain your custom settings. When you visit one of these sites, a cookie is placed on your computer. Each time you visit another site that hosts one of their ads, that same cookie is read, and soon they have assembled a list of which of their sites you have visited and which of their ads that you have clicked on. Cookies are used all over the Internet and advertisement companies often plant them whenever your browser loads one of their banners.

Cookies are NOT a "threat". As text files, cookies are inherently harmless and cannot be executed to cause any damage. Cookies do not cause any pop ups or install malware and they cannot erase or read information from a computer.
 

Cookies cannot be used to run code (run programs) or to deliver viruses to your computer. The purpose of a cookie is to tell the Web server that you have returned to a specific Web page.

Microsoft's Description of Cookies



Cookies are short pieces of data used by web servers to help identify web users. The popular concepts and rumors about what a cookie can do has reached almost mystical proportions, frightening users and worrying their managers.

Do cookies pose a security risk?

Flash cookies (or Local Shared Objects) and Evercookies are a newer way of tracking user behavior and surfing habits but they too are not a threat, and cannot harm your computer.

1. An Evercookie is a Javascript-based application which creates Zombie cookies that can be used to identify a user even after they have removed standard and Flash cookies. This is accomplished by creating a new cookie and storing the data in as many storage locations (currently eight) as it can find on the local browser. Storage mechanisms range from Standard HTTP and Flash cookies to HTML5's new storage methods. When evercookie finds that other types of cookies have been removed, it recreates them so they can be reused over and over.

2. Flash cookies are cookie-like data stored on a computer and used by all versions of Adobe Flash Player and similar applications. They can store much more information than traditional browser cookies and they are typically stored within each user’s Application Data directory with a ".SOL" extension, under the Macromedia\FlashPlayer\#SharedObjects folder. Unlike traditional cookies, Flash cookies cannot be managed through browser controls so they are more difficult to find and remove. However, they can be viewed, managed and deleted using the Website Storage Settings panel at Macromedia's Support Site. From this panel, you can change storage settings for a website, delete a specific website or delete all sites which erases any information that may have been stored on the computer. To prevent any Flash Cookies from being stored on your computer, go to the Global Storage Settings panel and uncheck the option “Allow third-party Flash content to store data on your computer”. For more information, please refer to:

As long as you surf the Internet, you are going to get cookies and some of your security programs will flag them for removal. Anti-malware scanners have more important things to look for, so I would recommend disabling the option to search for cookies which will also decrease the amount of time it takes to perform a scan. You can minimize the number of cookies which are stored on your computer by referring to:

I have performed all items on all three of the links you have supplied per my post. I have also requested assistance in the Firefox Support support forums and was referred to this forum. Perhaps there is not an infection; however, there is an issue somewhere. Should I post under a different forum?

If you think your may have picked up some adware/PUPs, check Programs and Features (Add/Remove Programs) in Control Panel for newly installed software and remove anything you do not recognize or did not download recently. In most cases, using the program's uninstaller not only removes it more effectively, but it also restores many changed configuration settings. Alternatively, you can use a third-party utility like Revo Uninstaller Free or Portable and follow these instructions for using it. Revo will do a more thorough job of searching for and removing related registry entries, files and folders.

After uninstallation, then you can run specialized tools like Malwarebytes Anti-Malware, AdwCleaner and JRT (Junkware Removal Tool) to fix any remaining entries they may find.

I will provide instructions after doing the above.

I have ran Revo and did not find anything out of the ordinary. I did use it to uninstall Firefox and then reinstalled Firefox only to still have the same issue. I didn't see anything strange upon scans. Perhaps it is just an issue with Firefox. I think I am going to just revert back to Firefox 29.x and call it a day. I have been working on this for 3 days now and there doesn't seem to be any known issue.


Thank you for your assistance.
