So far it has behaved as an excellent antivirus program, I like its interface is easy to use due to its simplicity, (for me the best software are those that are easy to use) has good performance, unlike other antivirus this is quite light, recognizes and removes a lot of viruses, has frequent updates, one of the features that I particularly like is that when you start the pc tells you the time it takes to run, which gives you an idea of the performance of your computer . One of the features that I am using recently and I have found excellent is the space release, since it has detected all those files that accumulate on the computer and that are not used and just take up space, this feature has allowed me to release up to 500mb which is very important to me.

Perhaps one of the characteristics of this program is very good, but at times it is not so good, it blocks programs or applications that are safe to install or execute and it does not allow it, so it must be temporarily disabled to be able to install or execute certain programs.

It presents one of the best self-protection against a wide variety of viruses and Trojans, with a low consumption of system resources. It has a clear interface and very easy to use. Additionally, it allows managing the control of permits for potentially risky applications and those that are safe. It is integrated with an excellent accelerator and system data junk cleaner that helps improve equipment performance quickly and safely Review collected by and hosted on G2.com.

The control of permissions asks for excessive notifications to the user, and if this one does not have much knowledge he does not know what to do. On the other hand it has limitations for the protection of electronic mail and the updates of the product are not automatic, you must download and install the new version available.

Is all in the same program , firewall , dirver , virus , performance , even updater , that's a tool a put my money on. Also is super ligth and does not force my computer to work overclock . the premiun base is not very expensive and can be purchase using diferent ways . The updater of windows is simple , just gets active automatic way and i do not need to worry. The Driver finder is really good , it gives you the best driver to release the best performance of my computer. Review collected by and hosted on G2.com.

What i see is not so much a dislike just a error because some translations to spanish are not exact term , other point is that the advertising is really disturbing is not even for something i wil buy is some random stuff i really don not see. Review collected by and hosted on G2.com.

The best thing is that it is a comprehensive system with many functions, not only is it antivirus, but it also offers many support tools for maintaining and cleaning the system, from cleaning and debugging temporary files and correcting registry errors, including integrity analysis of the hard drive, you can also program without problems to run at any time according to our needs and solve problems automatically and even turn off the computer. many benefits included in one place Review collected by and hosted on G2.com.

the only problem is that there are many secure applications, even applications of the same system that the software detects as threats and blocks its execution or installation therefore it is necessary to deactivate it to install certain things, and it is necessary to add them to the list of trust in order to use them Review collected by and hosted on G2.com.

I consider it the best free antivirus, not only because of the excellent detection it has of all types of threats, it can be found anywhere you have them on my PC. It also has very good protection modules, modules that only other paid antivirus offer, how Web Cam protection, USB protection, optimizer, Wifi security and the Sanbox to open or execute suspicious files without the risk of affecting the system. I like it a lot because it's lighter than avast, avg, panda, etc. And its installation is very fast and in terms of its interface is very fast. Review collected by and hosted on G2.com.

Since I use this software I have not had problems with it. The only thing is that I would like it to have more tools that I can only have with the premiun version. Although it is very good, it does not fully examine all PC viruses. But it usually eliminates the majority. Review collected by and hosted on G2.com.

Its ability to provide security patches for our operating system. Review collected by and hosted on G2.com.

For now, there is nothing, I like this product. Review collected by and hosted on G2.com.

It is an antivirus software that comes from China where it enjoys great popularity, with a huge user base on both computers and smartphones. The best thing about this antivirus is that:

1) It has the features of a paid one but is completely free.

2) It protects our PC from any threat that affects the performance of our resources (RAM, disk, CPU, and network).

3) Easy to download and install.

4) Intuitive, user-friendly interface that makes it easy to work with.

5) Besides being an antivirus, it has functions to free up space, anti-malware, to speed up the performance of the processor and RAM.

6) It has a counter and a log of the times it takes for the computer to start up, so we can see how many processes start when Windows boots and get an idea of the junk programs that slow us down at startup.

7) By enabling its extension in our browser, it blocks malware sites that could damage our PC, in addition to protecting our card information for online shopping. Review collected by and hosted on G2.com.

What I don't like:

It's true that it's free, but it has too many ads that are annoying. Although you can remove them by paying.

It's not cross-platform, we don't have a version for Linux.

When it's running with all its engines, it consumes a lot of RAM, which significantly slows down the PC if it's not a high-end one, even freezing your system.

If you use it on a laptop, Quihoo running with all options enabled quickly drains its battery. Review collected by and hosted on G2.com.

First of all It's free!!

has a simple and easy to use interface.

It offers a VPN tool, although it must be downloaded and installed separately

The Internet protection performs an analysis of downloaded files.

It has USB drive protection and automatic file scanning.

The full verification option allows you to execute the options in a single task, speed up, virus scan, clean junk files and WiFi security , just clicking the "verify" button.

It has an option to activate bit defender and Avira engines.

It has a tool called sandbox that allows the execution of programs without put at risk the system. Review collected by and hosted on G2.com.

It usually fails in the real time protection , so it's necessary to perform the scans manually.

Bitdefender and Avira antivirus engines are not used by default and must be done manually to increase protection.

includes a lot of ads!

slow down the startup time!

Many of the additional tools "included" can't be used unless you pay. Review collected by and hosted on G2.com.

The experience has been formidable, resulted in a very secure program and exceeded expectations by adding other services in addition to the detection, protection and elimination of malicious programs, the PC accelerator and space release are really efficient and are very useful as add-ons to the program .

We have installed it on all the computers in the office since it generates a lot of security and protection when browsing and generating file downloads. Review collected by and hosted on G2.com.

It has many services available which makes it more complex to handle it in its entirety for each user and take more time for its correct learning and use, the most efficient tools require a premium license.

It is a little aggressive to detect dangerous files which makes it difficult to manage and make decisions before it is removed. Review collected by and hosted on G2.com.

It integrates anti-virus software and tools for cleaning temporary files, freeing up memory space, and uninstalling software and removing all related records. All of these features are free without any charge. To use with Qihoo 360 antivirus package, it suggests users switch to Qihoo 360 web browser too, which can customize content filters and remove ads. It also offers online services to help users to repair their computer systems for an extra cost. The user interface is simple and direct, users are easy to find buttons for what they want to do. Review collected by and hosted on G2.com.

In the process to install Qihoo 360, instructions are not clear and users can be guided to install the entire package which some tools may not be used later. When running Qihoo 360, it eats so much memory of my computer and so I think to gear up your computer before start using it can give you a better experience. Also, since it was developed by a Chinese company, it offers only one language as far as I know. When I used it before, it sometimes was detected as an unclaimed software and suggested to remove from my computer according to the firewall or other antivirus software. I do not know if it is caused by the conflict between companies or not. Review collected by and hosted on G2.com.
