Reubenking concluded “The biggest win for Comodo Internet Security Complete 2013 isn't in features, but in support. The GeekBuddy service fixes any problem, security or otherwise, using remote assistance. A Virus-Free Guarantee reimburses you for damage if malware gets past Comodo; you can also get reimbursed for expenses related to identity theft. Add a GeekBuddy-powered tuneup tool and an unusually powerful backup utility and you've got a winner.“

He noted that with recent versions of Windows including a firewall it is important that alternative products be free and provide additional features, which are true for the Comodo Firewall.

It offers a wealth of bonus features including a hardened browser, sandboxing, and secure DNS lookup."

Symantec vs. Comodo 
In response to Symantec's comment over the effectiveness of free Antivirus software, on September 18, 2010, the CEO of Comodo Group Melih Abdulhayoğlu challenged Symantec to see which products can defend the consumer better against malware. Symantec, the producer of Norton AntiVirus, has responded that such direct tests are unnecessary: "Norton is included in a variety of independent, third-party tests from testing labs like AV-Test and AV Comparatives. We encourage Comodo to contact these testing labs if they are interested in having their product included in these tests."
On 29 September 2010, Neil J. Rubenking, the lead analyst for security of PC Magazine, published an article on Comodo Antivirus 5.0 that included a comparative chart. Rubenking concluded that Comodo Antivirus 5.0 blocked a higher percentage of malware than Norton AntiVirus, but was less effective than the Norton solution when it came to malware removal. Rubenking's review also noted that the Comodo malware blocking gave a number of false positives which he felt tarnished Comodo's results.
2011 affiliate registration security breach 
On March 15, 2011, Comodo reported that a user account with an affiliate registration authority had been compromised which was used to create a new user account that issued nine certificate signing requests. Nine certificates for seven domains were issued: mail.google.com, login.live.com, www.google.com, login.yahoo.com (three certificates), login.skype.com, addons.mozilla.org, and global trustee. The attack was traced to IP address 126.96.36.199, which originates in Tehran, Iran. Though Comodo initially reported the breach was the result of a "state-driven attack", it subsequently stated that the origin of the attack may be the "result of an attacker attempting to lay a false trail."
