Careers at Malwarebytes


Malwarebytes’ mission is to create the best disinfection and protection solutions to combat the world's most harmful Internet threats.


When he was in high school, Marcin Kleczynski accidentally downloaded an infection onto his computer, which was protected with anti-virus software. He visited a forum called SpywareInfo to see if he could solve the problem. A fellow visitor helped him realize the issue was not a virus, but malware, and helped him remove it within three days. Still, Kleczynski was bothered it took that long.

His frustration motivated him to learn how to write software to eliminate malware. He developed a utility that combatted a specific type of infection, and it became popular on the forum. A forum member told him about an inactive domain he had called Malwarebytes, and asked him if he wanted to use it to promote the utility. Kleczynski agreed, and began giving the program away as freeware.

Klecyznski  later enrolled in college to study Computer Science. While there he met a tech shop worker who gave him useful feedback on his malware programs, Bruce Harrison. They spent a year developing his high school project into a viable product. In 2008 they founded a company called Malwarebytes to market it, and began selling it to the campus body with the name “Anti-Malware.“

The two utilized a freemium model, providing a basic version at no charge and a premium version with advanced features. They updated the software frequently and avidly solicited community feedback for improvements. Over time the firm became profitable, and they built a support and sales team. Eventually, Malwarebytes garnered corporate customers and became a significant player.

Business model of Malwarebytes

Customer Segments

Malwarebytes has a segmented market business model, with customers that have slightly different needs. The segments are consumers, small/medium businesses, enterprises, and non-profits.

Value Proposition

Malwarebytes offers five primary value propositions: accessibility, pricing, performance, risk reduction, and brand/status.

The company creates accessibility by offering a wide variety of options. Its solution identifies and removes malware on PCs and phones using next-generation anti-malware, anti-spyware, and anti-rootkit techology. Specific types of malware addressed include worms, rogues, bots, spyware, rootkits,  and Trojans. It integrates with a wide variety of third-party security platforms that may already be on users‘ computers. Lastly, it is available in over 30 languages, making it usable by many.

The company offers a pricing value proposition. It offers a basic version of its software for free. It also offers a 14-day free trial for its premium version. Lastly, customers who upgrade from premium to basic receive a 50% discount.

The company has demonstrated strong performance through tangible results. Its solution features a setting called “Hyper Scan Mode“ that only targets active threats, making it analyze computers at a lightning-fast speed.

The company reduces risk by maintaining high security standards. Its solution not only removes existing infections, but prevents future ones by running continuously in the background. This real-time protection enables it to easily halt attempted attacks. This task is accomplished through the use of three proprietary technologies – signature, behavior, and heuristics. Its solution also prevents malware from removing the solution itself from devices through its Chameleon technology.

The company has established a strong brand due to its success. Its software has fixed over 250 million home computers, with an average of six PCs repaired every second. It has received over 200 million downloads worldwide and removed more than five billion pieces of malware. It is used by over 10,000 companies. Lastly , it has won many honors, including the following:

  • Three Stevie Awards (two gold, one silver) at the American Business Awards (2016)
  • Ranking as one of America’s “Most Promising Companies“ by Forbes (2015)
  • Ranking as one of the“10 Best Medium Workplaces in Technology“ by Fortune (2016)
  • Recognition of Malwareby­tes Anti-Malware 2.0 as the“Best Security Product“ by CRN (2015)


Malwarebytes’ main channels are its direct sales team and its website. The company promotes its offering through its social media pages and participation in expos and conferences.

Customer Relationships

Malwarebytes’ customer relationship is primarily of a self-service, automated nature. Customers utilize the service through the main platform while having limited interaction with employees.  The company’s website features a “Resources” section that includes tech briefs, case studies, data sheets, infographics, and webinars.

The site also features a “Support” section that includes user guides (consumer guides, business guides, legacy guides, and miscellaneous guides), and answers to frequently asked questions. Customers can also sign up for access to an e-mail newsletter.

Despite this orientation, there is a personal assistance component. The company offers three support service plans, which are as follows:

  • Premium – Provides phone and e-mail support
  • Premium Silver – Provides a designated Technical Account Manager (TAM) who guides clients from initial implementation through future upgrades
  • Premium Gold – Provides a TAM and a Customer Success Engineer who support all aspects of clients‘ accounts and ensure clients‘ technical issues receive priority status

Lastly, there is a community element in the form of a forum where clients can interact with peers.
