There are many antivirus options available, but Kaspersky is trusted by millions of users worldwide and our security plans have been consistently ranked as the best antivirus programs on the market. Our new security plans provide advanced security features, such as multiple layers of protection against various threats, real-time scanning, and frequent updates to keep your devices secure.

Antivirus and anti-malware software are both designed to protect your computer from online threats, but they differ in terms of their scope of protection. Antivirus software is primarily focused on preventing viruses, worms, and other forms of malware from infecting your computer, while anti-malware software is designed to detect and remove a wider range of online threats, including viruses, spyware, Trojans, adware, and more.

Kaspersky Anti-Virus features include real-time protection, detection and removal of viruses, trojans, worms, spyware, adware, keyloggers, malicious tools and auto-dialers, as well as detection and removal of rootkits.

Microsoft Windows users may download an antivirus rescue disk that scans the host computer during booting inside an isolated Linux environment. In addition, Kaspersky Anti-Virus prevents itself from being disabled by malware without user permission via password access prompts upon disabling protection elements and changing internal settings. It also scans incoming instant messenger traffic, email traffic, automatically disables links to known malware hosting sites while using Internet Explorer or Firefox, and includes free technical support and free product upgrades within paid-subscription periods.[4]

Kaspersky Anti-Virus lacks certain features found in Kaspersky Internet Security. These missing features include a personal firewall, HIPS, Secure Keyboard, AntiSpam, AntiBanner and parental control tools.[4]

In 2005, two critical flaws were discovered in Kaspersky Anti-Virus. One could let attackers commandeer systems that use it,[6] and one allowed CHM files to insert malicious code.[7] Days later, the software maker had offered preliminary protection to customers, and a week later a permanent patch was made available.[8]

An edition of Kaspersky's anti-virus solution for Linux workstations is available to business consumers.[9] It offers many of the features included in the mainstream version for Windows, including on-access and on-demand scanners.

The newly released Macintosh capable edition of Kaspersky Anti-Virus is compatible on (Intel Processor Based) Mac OS X Tiger and higher to include the brand new version Mac OS X Snow Leopard, released in August 2009. Kaspersky Lab internal testing concludes consuming only 2% CPU impact on performance and is designed to maintain a user friendly Mac-like interface with which Mac users are familiar. Kaspersky Anti-Virus for Mac contains definitions to detect and block malware affecting Windows, Linux and macOS alike. Kaspersky Anti-Virus for Mac also scans shared folders of users running Windows using Virtual PC on capable Apple Macintosh personal computers.[10]

A DVD-ROM or CD-ROM drive, Internet Explorer 8 or above and Windows Installer 3.0 or above are also required for the installation of Kaspersky Anti-Virus in Windows. The latest version can either be downloaded from their official website or purchased through retail.

According to AV-Comparatives, Kaspersky Anti-Virus rates highly amongst virus scanners in terms of detection rates and malware removal, even despite the fact that the program has failed two Virus Bulletin tests in 2007 and another two in 2008.[11] For example, in a Malware Removal test done by AV-Comparatives the Kaspersky Antivirus 2013 was awarded the highest "Advanced+" rating and was able to successfully remove all of 14 malware samples used in that test and in the following File Detection test Kaspersky Antivirus 2013 was also able to achieve the same "Advanced+" rating with a 99.2% sample detection rate.[12][13] In addition, PC World awarded Kaspersky Anti-Virus 6 the highest rank in its 2007 anti-virus comparative.[14] The well-known and highly regarded Ars Technica lists Kaspersky as one of the best choices for Anti-Virus on the Windows platform.[15]

In January 2024 Forbes Advisor compared Kaspersky with other tools such as BitDefender and Avast and rated Kaspersky in first place ("4.5" out of 5) of the platforms reviewed in their comparison exercise.[18]

In March 2015, Bloomberg accused Kaspersky of having close ties to Russian military and intelligence officials.[19] Kaspersky criticized the article in his blog, calling the coverage "sensationalist" and guilty of "exploiting paranoia" to "increase readership".[20]

In June 2015, United States National Security Agency and United Kingdom Government Communications Headquarters agents broke Kaspersky antivirus software for spying purposes[clarification needed].[21]

U.S. President Joe Biden's administration on Thursday banned Russia-based cybersecurity firm Kaspersky from providing its popular antivirus products in the United States over national security concerns, the U.S. Commerce Department said.

The announcement came after a lengthy investigation found Kaspersky's "continued operations in the United States presented a national security risk due to the Russian Government's offensive cyber capabilities and capacity to influence or direct Kaspersky's operations," it said.

U.S. Commerce Secretary Gina Raimondo said, "Russia has shown time and again they have the capability and intent to exploit Russian companies, like Kaspersky Lab, to collect and weaponize sensitive U.S. information."

Kaspersky, in a statement to AFP, said the Commerce Department "made its decision based on the present geopolitical climate and theoretical concerns," and vowed to "pursue all legally available options to preserve its current operations and relationships."

"Kaspersky does not engage in activities which threaten U.S. national security and, in fact, has made significant contributions with its reporting and protection from a variety of threat actors that targeted U.S. interests and allies," the company said.

The move is the first such action taken since an executive order issued under Donald Trump's presidency gave the Commerce Department the power to investigate whether certain companies pose a national security risk.

While Kaspersky is headquartered in Moscow, it has offices in 31 countries around the world, servicing more than 400 million users and 270,000 corporate clients in more than 200 countries, the Commerce Department said.

As well as banning the sale of Kaspersky's antivirus software, the Commerce Department also added three entities linked to the firm to a list of companies deemed to be a national security concern, "for their cooperation with Russian military and intelligence authorities in support of the Russian government's cyber intelligence objectives."

Kaspersky is allowed to continue certain operations in the United States, including providing antivirus updates, until September 29, "in order to minimize disruption to US consumers and businesses and to give them time to find suitable alternatives," it added.

I am not familiar with Kaspersky AV options, but if there is no option in settings you'd better don't fight with software that you installed yourself on your pc. If you don't like it - change it, otherwise accept it.

I personally prefer old antivirus versions (with newest database updates of course), because they do only what they should do and nothing more. They are not uploading "suspicious" files to their servers and not injecting anything.

Also I recommend anyone to buy only "AntiVirus", but not "InternetSecurity" or something like that, because that things cost a lot, don't work, slows your browser, and sometimes do some really suspicious things.

It sounds like Kaspersky implements some form of certificate pinning, so it is detecting the Sophos CA as a hijack attempt. Check with their support about which of their nany features needs to be turned off. Possibly they provide a special way to make the Sophos CA teusted.

I have not used Kaspersky in several years, but it seemed like they tried to cover many features, so they may have an https inspection module as well. If so, that is probably the module that needs to be disabled to allows UTM's https inspection to work.

I am familiar with this material, which is a warning that you need to inspect your HTTPS inspection implementation, not a warning to avoid its use. I have used UTM with and without HTTPS inspection. Chrome 58 forced me to turn it off and unstable UTM updates have prevented me from using the newer versions. If you are a member of ISC2, I have an article on the technology (but not the UTM implementation) appearing in this months issue.

Unlike the primary fear in the UT-CERT link, UTM not only enforces certificate chains, it enforces them too strictly. Many sites have missing intermediate certificates or included root certificates. Missing intermediate certificates can be obtained using AIA fetching, which is why the problem is not visible in any major browser. UTM does not have the feature, so it blockes these sites. Included root certificates can be ignored if the root certificate is already installed on the receiving device, but the OpenSSL version used in 9.4 did not have the logic to do so. As a result, any chain that ended with a root certificate was blocked because of the self-signed cert.

(2) The available ciphersuites can be configured from the shell environment with help from Sophos support. One article on this topic specifically cited UTM for having RC4 enabled for outbound connections. I think this default setting has changed but I know it is configurable in the shell. UTM has already disabled TLS 1.0 by default in one of the 9.4 releases.
