Qihoo 360 Total Security is a completely free online security & antivirus solution developed by Qihoo. Its antivirus protection is powered by two major third-party vendors. But is this program merely a repackaging of other tools or does it have independent value?


Antivirus protection forms the vi xử lý core of this security suite but the engines that make this work are actually Avira & BitDefender. For those who need reliable protection, that’s great news: both these scanners have fared excellently in independent reviews.

There are three scanning options: a quick scan (which is very quick – mine took less than five minutes), a custom scan, & a full system scan. There’s also a built-in Patch-Up feature which automatically checks your installed programs to make sure they’re not outdated or contain vulnerabilities. If the system detects a program with an available update, details of the upgrade and a link to tải về the new version will appear.

This is a great feature—outdated software is a hacker’s goldmine (67% of computers affected by the WannaCry virut were running an outdated version of Windows). In addition to the vulnerability scanner, the software also looks for other “system anomalies” after running. It automatically flagged a “promotional tag URL navigation icon” and quickly resolved it during my test.


Qihoo 360 Total Security is more than just a vi khuẩn scanner. The comprehensive speedup và cleanup tools improve the state of your system by removing unnecessary startup applications and files. There’s also a handy graphic of your system’s average boot time so it’s easy to lớn track progress as you turn off unnecessary startup services (which can drastically slow down your system’s loading time)


If the automatically pre-configured speedup tools aren’t to your liking, Total Security also provides a “Manual” thực đơn which gives you control over system settings. Finally, the “history” panels allow you to lớn see any changes to lớn your system optimization settings. These tools integrate nicely with the “scheduled cleanup” function.

Other online security tools include a data shredder for securely deleting unwanted files & folders (free trial on the basic plan và available permanently with the Premium upgrade), a virtual sandbox environment for safely examining potentially malicious programs, a virtual vault for storing passwords, and a ransomware decryption tool. This tool aims to lớn break the encryption that ransomware uses to lock down access khổng lồ your files & directories, so it’s a second line of defense against this cybersecurity threat.


Ease of use

Downloading Qihoo 360 Total Security involves a relatively straightforward, two-step process (an executable is downloaded from the website, which subsequently downloads the definitions and components that the program needs to lớn run). I lượt thích the fact that some of the add-on modules (such as the ransomware decryption tool) are not included out of the box and instead have to downloaded after the initial installation has been completed. This helps keeps the form size and speed of the initial tải về relatively manageable. After installation, the tool is very easy khổng lồ operate. A notification icon keeps users apprised of system alerts without being intrusive & the assortment of extra tools can be accessed from the “tool box” menu. Overall, this is a very nicely designed piece of user-friendly software.



Qihoo 360 Total Security is a completely không tính tiền software, so it’s expected that the support resources are not as far-reaching as those from a paid title. Nevertheless, the company offers a basic online Q&A to help users resolve common issues, such as installation or manually updating the vi khuẩn definitions. However, telephone và live chat support are both notably absent and the e-mail ticketing system can only be accessed by users that have upgraded to Qihoo 360 Total Security Premium.

Qihoo 360 Total Security is a completely không lấy phí product—so there’s nothing khổng lồ complain about on the price!

The company does offer a Premium upgrade, however, which gives access lớn additional tools like a firewall editor, a privacy cleaner, an in-app ad remover, & first priority tư vấn (which offers thư điện tử ticketing). 360 Total Security Premium is very reasonably priced—particularly when purchased at the three-year, three-device level. Premium plans also include a 30-day money-back guarantee.
