Pros Cons Verdict
Simple interface No way of knowing the end of a scan    An easy-to-use application with an average detection rate
More features than virus scanning Scan results are not great
On the market for more than 15 years A full scan takes a long time to complete

Download and installation

Downloading and installing STOPzilla AntiVirus is very simple. You can get the anti-malware application from our page. The download will be quick as the installation file is very small.

STOPzilla AntiVirus is compatible with Windows 10, 7, 8, and Vista; also, there is a mobile version for Android devices too.

To begin the installation, open the file that you downloaded and follow further instructions. There should not be any problems with that and you will have the program installed in a minute.

The installation should not last more than a minute.

It is good that the installation file is very small-sized. The download should not take long even for users with a slow Internet connection.

After the installation is completed, a quick scan will be performed immediately. There are many similar programs, which perform full scans after the installation. It can take up to 30 minutes or even more. Not everyone wants to perform such a long scan without their permission. So, a quick scan is a really good idea.

Test results

We used STOPzilla AntiVirus for about 30 days. The computer that we tested this software on had the Intel i5 processor, 8GB of RAM and HDD. The operating system was Windows 10 (64 bit). This software worked well on this computer.

Antivirus protection

STOPzilla AntiVirus uses antivirus engine by Bitdefender. It also uses Bitdefender malware signatures, and the signatures are an only hour older than the original Bitdefender signatures. Keeping in mind that Bitdefender offers one of the most advanced antivirus protection in the market, we expected advanced results from STOPzilla. The application automatically quarantines the threats and users cannot change this feature. Once installed, the antivirus started its’ job with a quick scan.

STOPzilla AntiVirus’s quick scan did not find anything, although there were a few infected files on the system.

The full scan also disappointed us a bit. It is always recommended to perform the full scan for the best results. While the quick scan is only for checking the surface of the system, the full scan will dig out infected files even from the deepest locations of your computer. What disappointed us, is that the full scan also could not detect any infected file, even though our test computer was infected with some malicious programs and dangerous software.

We tried to look for reviews on the internet by independent antivirus testing labs, such as AV-TEST, however, STOPzilla did not participate in any, so it is hard to predict how the application would have been rated in bigger tests.

Additional features

The antivirus program includes many features, such as Active Antivirus Protection, Web Filter, Application Whitelist, Conserve Battery Power, Smart File Cache, Enhanced Malware Detection Engine, Scan Mobile, Root-kit Scanning, Removable Drive Scanning, and Gaming Mode. The feature set looks very decent if you do not need any advanced mid-level security suite features. However, for the price of STOPzilla, you can probably find better protection with a more decent set of features.

System-performance impact and scans

We did not notice any bigger slowdowns caused by the application. However, it uses a quite big amount of system resources, especially while performing a scan. 

There are three scan types:

  • Quick scan;
  • Full scan;
  • Custom scan.

However, the test results are average and there were some issues with scanning.

Although the quick scan should be quick, it takes a few minutes to complete[3]It may look like these few minutes is not much, but there are other similar antivirus applications that complete a quick scan much faster and more effectively.

STOPzilla took almost an hour to complete scanning and it couldn't find a single infected file.

Another missing feature is the scan process percentage or a loading bar. Now it is only possible to see how much time passed since the scan has started, but you cannot see how much time is left until the scan will be completed.

User interface

The interface[4] and the menu arrangement are very clear and nice. Every user would easily find a feature that they want.

Customer reviews

There are many reviews about anything on the Internet, and STOPzilla AntiVirus is not an exception. There are positive and negative reviews too, but, like all products, STOPzilla AntiVirus has some very negative and false comments.

Contact the customer support if you have problems with STOPzilla.

These false comments usually are written by people who did not understand how to use the program properly, or other companies, which want to spread wrong information about other software.

If you have any problems with STOPzilla, always contact their support and you will not be disappointed.

However, we also saw many positive reviews focusing on the efficiency and reliability of the application.

Feature Score
Antivirus protection Poor
Additional features Decent set of Antivirus features
System-performance impact Mediocre
Scanning performance Slow scans
User interface Simple and easy to use

The final verdict

The software itself is very reliable and simple. It can be easily used even by a person who has never used this kind of program because every feature can be found in a matter of seconds.

Although STOPzilla AntiVirus is on the market from the year 2001, there still are some issues – a simple scan takes about an hour to complete and it is not very effective against all the threats.
