I scanned my computer with Norton and it said threats detected. When I click fix now it directs me to the website to buy Norton 360 or Norton Internet Security.

When I scanned my computer with Windows Defender, it shows no threats or viruses. Here's a screenshot:

    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.

    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.
    1. 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:

    Then something is wrong.

    When Avira is correctly installed, Windows Defender should be automatically disabled.

    You can't have 2 real time protections running at the same time.

    Did you ask Avira support? https://www.avira.com/en/support

    Did you read and follow up on the links I supplied earlier?

    Please clarify:

    You posted in Windows 7 category - is your OS indeed Win 7?

     Windows Defender (on Windows 7, Vista, and XP) provides spyware protection only. 

    What's your Anti-Virus-product?

    You need to install an Anti-Virus product.

    You might want to have a look at:

    Microsoft Security Essentials Consolidated FAQ

    ====

    I see AVG Secure Search (which is a browser hijacker) in the Norton screenshot.

    See this free, multi-step removal guide: http://malwaretips.com/blogs/avg-secure-search-virus-removal/

    In case you can't do a step, move on with the next steps.

    Note: scanning with Hitman Pro might not be necessary.

    Re: Norton Security Scan read: http://www.shouldiremoveit.com/Norton-Security-Scan-6587-program.aspx

    Note:  This is meant as a information only. Do NOT click on any Download link on the Should I remove it -page.

    I strongly suggest to uninstall Norton Security Scan and to use also the Norton Removal Tool. See here: List of anti-malware product removal tools
