Scanning Web Cookies: Kaspersky Antivirus on Keeping You 100% Secured

You see them every time you open websites – pop-ups asking you to allow cookies on your web browser. But what are cookies? Why do you need to accept web cookies? Why do experts, especial Kaspersky Antivirus experts, have warnings against letting cookies in your browser?

A cookie is a text file that a Web site can install on your computer. Cookies enable a Web site to tailor pages presented to you by storing information about you in the cookie text file. The Web site can remember you for easy navigation and access during your return visits for products, services, and content. Advertisers may use this information to understand your Web surfing habits. Cookies are only text files and are NOT worms, viruses, or directly malicious, but they may have privacy implication.

Tracking Cookies are a specific type of cookie that distributes, shares, and reads across two or more unrelated websites to gather information or potentially to present customized data to you.

But not all cookies are tracking cookies. Tracking cookies are not harmful like malware, worms or viruses, but they can be a privacy concern. As an example, if you go to a Web site that hosts online advertising from a third-party vendor, the third-party vendor can place a cookie on your computer. If another website also has advertisements from the third-party vendor, then that vendor knows you have visited both Web sites.

Are these advertisers directly targeting your specific browsing habits? Most likely, not. The information is from over thousands or millions of users to determine overall trends in Web surfing.

Are Cookies Dangerous?

Contrary to what some users may think, cookies are NOT inherently malicious or dangerous. If you run a scan with your antivirus software, and you find a tracking cookie, the tracking cookie does not represent a malware infection. These are low to minimal security issues. We have seen many security companies and free “Spyware Removal Tools” emphasize detection of cookies, calling them Spyware and Trackware and stating that you are “infected”, which is most unlikely to be the case. Cookies and the information they store are more related to privacy concerns.

To determine if the privacy concern is an issue for you, you need to decide if the benefits of today’s Web site customizations outweigh the sensitivity of the information we provide. This is very similar to the power and flexibility of using major search engine technology and giving your frequent shopper card at your local grocery store – each has potential benefits and downsides. A search engine is helpful for quickly and easily finding information, but the search engine companies could potentially know about the types of things you search for and which links you decide to go to.

It is typical for us to receive precise information, but our privacy is what may suffer as advertisers and corporations learn more about our Web surfing habits.

How Can a Cookie Threaten a Computer?

A cookie itself cannot harm the computer, as it does not and cannot hold code (therefore the cookie cannot act itself). However, the cookie can support (help) malicious actions to be taken on the respective system. Even more, being a plain text file, they are vulnerable, meaning that they can be “harvested” by other applications.

Why is it Necessary to Scan Cookies with Kaspersky?

As already mentioned the cookies themselves cannot harm the computer. However, they can contain certain information to lead a possible attacker to the respective computer. For example, we will consider that an attacker releases a Trojan in the wild to gain control over several computers.

This Trojan’s payload contains in dropping a Backdoor (to open a port), changing the homepage of the browser and placing a “malicious” cookie in the browser’s cookie area. When the unsuspecting user launches the browser, then it automatically connects to the new homepage (namely the attacker’s website). Once this is done, the malicious cookie is being read. The attacker becomes aware of the fact that the computer is infected. By knowing this, it becomes a piece of cake to take over the computer using some exploits or the open port.

Let’s say that the user becomes aware of the infection and manages to remove the Trojan and the Backdoor from the computer. However, if the cookie remains on the computer, it can resupply the information to the attacker if the user “manages” to reaccess the untrusted web page. The computer is therefore exposed once again to a possible attack.

As explained in the above scenario, the cookie is used to provide information about a computer. However, it is not responsible with the attack itself.

So it is always safe to run your antivirus to detect malicious intent. Among the hundred antivirus software out in the market, Kaspersky is always on the top 10 software pronounced by AV testing labs. Kaspersky antivirus software has scan features that can detect hidden threats, making web cookie scan highly successful.

Online Threat Detection by Kaspersky

Kaspersky antivirus software‘s malware aced the most-recent tests by the three malware labs whose results we use, delivering excellent protection without any false positives.

In both the zero-day and widespread malware categories, Kaspersky Antivirus got perfect 100% detection scores. These were categories surveyed by German lab AV-Test in May and June 2019. Norton, Trend Micro and Microsoft Defender matched those scores as well. However, Norton racked up three false positives while the others had none.

In all of AV-Test’s bi-monthly evaluations dating back to January 2017, Kaspersky did not get a perfect score only in ONE out of 60 tests. Kaspersky was also perfect in Austrian lab AV-Comparatives’ February-May 2019 tests, detecting 100% of online malware with no false positives.

Finally, London-based SE Labs gave Kaspersky the highest rating in tests conducted from April through June 2019. They gave the same rating to ESET, Microsoft and Norton. Each detected 100% of malware without any false positives. However, Microsoft arguably won by a hair because the other three neutralized rather than blocked 1% of malware.

Other Types of Malicious Attacks Using Cookies

A similar case shows the fact that cookies are vulnerable to third party attacks. Lately, virus analysts like Internet Explorer, Mozilla Firefox, and JavaScript discovered exploits. They discovered vulnerabilities that allowed attackers to harvest information from cookies. Attackers use either different cookies or spyware software (for example login information for different servers the customer might use).

Conclusion: Kaspersky is Tough on Cookies

When talking about cookies, it’s important to know how to protect cookies from other cookies or applications. It is also important to know how to protect a computer against cookie attacks. Since cookies are necessary for browsing, a “cookie control” module would be great. Cookie traffic is invisible to the computer user, so cookie management helps users too.

It is not necessary to get multiple plans or products to keep your PC secure from cookies. You can get Kaspersky Total Security to cover Windows with one subscription. It keeps you protected from emerging threats, and this antivirus package from Kaspersky is both efficient and affordable.

Bitdefender Internet Security is also a great option. It detects both viral and spyware attacks using the signature-based mechanism. This feature is in the default configuration of the product. Customers do not need to perform further actions for this matter.

Both these trusted security software is available at Softvire Australia, your trusted supplier of the best software at the cheapest prices.
