Comodo Internet Security Pro 2027 is back for a full re-test!
Comodo Internet Security Pro combines antivirus protection, firewall capabilities, behavioral detection and its famous sandbox technology to protect Windows systems against malware and other threats.
Since my previous test, the developers have fixed several issues that were identified during the original evaluation. So, rather than simply relying on the previous results, I decided to give Comodo another chance and test the latest version from scratch.
In this re-test, I put Comodo Internet Security Pro 2027 through a new series of real-world security tests, including malicious URLs, malware samples, ransomware and other threats.
Have the fixes made a difference? How does Comodo perform now?
Let's find out!
Interface :
The interface is identical to that of the 2026 version. The new feature is in the configuration: Comodo now includes EDR!
In fact, the EDR will detect dangerous behavior and attempt to mitigate the ongoing attack. This is a major plus.
The antivirus is also trying to become a bit more accessible to beginners, even though it remains geared toward advanced users.
During installation, I accepted Comodo’s secure DNS and cloud-based scanning.
Malware URL : 8/8
The anti-malware engine detected a piece of malware.
The rest was sent to its sandbox for isolation.
No damage was caused.
Malware Pack : 114 out of 168 threats remain
Let's be honest: Comodo doesn't exactly shine when it comes to its engine's detection rate. I think its engine is really just a secondary feature.
On the other hand, its isolation is very good. The issues I had noticed have been properly fixed; Comodo isolates threats correctly.
Even though I had to restart the machine because the Unicorn worm tried to overload the RAM, there was nothing left active after the restart.
Final scan :
Comodo : 0
Emsisoft : 16 (traces in the Sandbox and on the system; not active)
Final opinion:
Comodo listened to the feedback and completely overhauled the software.
The Sandbox bugs have been fixed, and the software seems to run more smoothly than before.
What I find unfortunate is that its anti-malware feature seems to have been completely neglected, given its very low detection rate, and the same goes for its web filtering (both software-based and DNS-based): it didn’t block a single page!
It’s finally back among the top-rated programs; it’s worth recommending, but not for beginners—it’s still quite complicated for them. Intended for advanced users.
(There's a surprise at the end of the video—Comodo fans, please don't be mad at me; I just couldn't help myself
