The Good

  • Great products
  • Notable features

Qihoo offers products which operate on several platforms and with good results in detecting and treating virus, malware and other threats.   They score at a comparable level with the competition and offer fairly comprehensive coverage without unduly slowing down users’ systems, according to several professional testers as well as via real-world reviews from Qihoo 360 Total Security users.

Some of the notable features of Qihoo 360 Total Security anti-virus software include:

  • Qihoo 360 Total Security uses the Avira and Bitdefender databases for their sources on the latest virus information.
  • Anti-keylogging is included as well as anti-webcam hijacking protection.
  • Users may select to enable automatic shopping mode or automatic gaming mode for additional protection during activities which make users more prone to attacks.
  • Qihoo 360 Total Security offers browser plug-ins for the most popular browsers – Internet Explorer, Mozilla Firefox, Google Chrome.
  • Qihoo 360 Total Security does not require extensive system resources which can slow a computer’s operation.
  • Independent testing labs give Qihoo  good ratings in detection and removal of harmful software.
  • Qihoo 360 Total Security scores very highly by several independent testing labs for their anti-phishing protection.
  • Sandbox mode allows users to test programs in a safe environment to ensure that they are safe before these programs make permanent changes to their systems.
  • The system interface for Qihoo 360 Total Security is filled with easy-to-follow and oversized icons which control system functions.

The Bad

  • Difficult instructions
  • Basic protection
  • Limited company information

The information on Qihoo’s website is written in English which has clearly been translated from Chinese and some of the instructions are difficult to follow.  The company does not have access to live customer support or a US office or phone number.

Independent testing labs found that the default settings only offered basic protection, and in order to receive the full-benefit, one must delve into the interface more and enable all definition databases.  Doing so is not difficult, but might be daunting for novice users.

Qihoo’s headquarters and all employees are in China.  Information about the company itself is sparse.

In some detection tests, the product had a higher-than expected false positive rate compared to their leading competitors.  Additionally, the browser plug-ins do not scan for hidden URL-redirects.

The Bottom Line

Qihoo 360 Total Security has many positive features in a free software protection product.  Disturbing is the fact that the product which the company supplied to CNET and other testing labs for testing scored very highly, but CNET later learned that their sample product was not the same one which was distributed to consumers.  As such, the independent anti-virus testing labs withdrew their certification of the Qihoo 360 Total Security product and CNET down-graded their review from 5 stars to 3.5 stars.

The product which is currently available online works well, but the lack of transparency and customer support are adequate for a cautionary recommendation.

Price Range

Qihoo 360 Total Security Essential, Qihoo 360 Total Security for MAC, and Qihoo 360 Safe Global Mobile (Android only) are all free of charge for download and protection.


Qihoo 360 Total Security anti-virus software products work with Windows, MAC and Android operating systems.


Qihoo 360 Total Security has an average to above average detection rating in finding most malicious software and in detecting threats, detecting 75% of the samples in a test designed and administered by PCMag testers.  Detection rates are much higher for users who have enabled all five of the anti-virus databases in the software settings though.  All Qihoo products score with comparable results to the competition.

In PC Mag’s testing, however, there was an anomaly which bears mentioning:

More worrisome was the fact that a full malware scan identified one of my handcrafted testing tools as malware. The name HEUR/QVM05.1.Malware.Gen suggests to me that Qihoo erroneously identified the file as malicious using generic detection methods. Generic detection can catch zero-day brand-new malware, but it needs to be tuned so it doesn’t quarantine valid programs.


In PCMag’s testing, Qihoo 360 Total Security detected and blocked 27% of malware downloads with the default settings and 54% with all of the databases and directories enabled.  The industry average for malware detection and protection is 40%.


During expert testing, Qihoo 360 Total Security performed better than many of the competition in that running the software did not cause significant system slowdown.

CNET’s Editors Rating

The last date of CNET Editorial Review for Qihoo 360 Total Security  was June 10, 2013.  Eddie Cho reviewed the product.  This review is dated for software products, but still contains information helpful to the user since the issues brought up are still valid.

360 Internet Security 2013’s installer is a light 17MB, and though the overall installation time and duration was relatively fast, it’s update process took longer than we had expected. Prior to installation, 360 will automatically prompt you to agree to their license and usage terms, something that’s normally an opt-out process. And though it’s more or less required to move on, those who are more keen on privacy details or interested in the terms of agreement should keep this in mind before they install the software. Still, the opt-out option might appear a bit suspicious, especially for users who are simply trying out the software.

360 Total Security Essentials Editors Review

CNET gave Qihoo 360 Total Security 4.75/5 stars and it is currently ranked as the third highest download in their library for anti-virus products.

Some of the other Qihoo software products available on CNET include:

  • 360 Browser
  • 360 Zip
  • 360 Browser HD (iPad)
  • 360 Battery Saver (iPhone)


At the present time, while the anti-virus protection products offered by Qihoo are rated with independent testing labs, they are not currently certified by many due to the company sending products which were different and which performed better than the products available via download for consumers.  As such, Qihoo lost their certified status with several labs.  Several companies are stripping Qihoo of their certifications, endorsements, etc.

PC World – Ranking Stripped

It is notable that on Qihoo’s website, some of these companies are still being touted as having certified or endorsed the company.   The two most prominent are AV-Comparatives and West Coast Labs.

Mobile Antivirus

Qihoo’s website offers mobile protection for Android devices. has some utilitarian apps available for download for iOS users, none of which are anti-virus products.

Android devices

The following are features available for Android devices via the Qihoo 360 Safe Global Mobile application, available in the Play Store at no cost: App Manager, Call & SMS Blocker, Privacy, Data Monitor, Antivirus Engine, Phone Cleaner, and Memory Booster.

Cleaning/False Positives

Independent anti-virus testing labs and experts, such as PCMag found that Qihoo had a slightly higher rate of false positives than the competitors, especially for those using the default settings.

Time in Business

Qihoo 360 Total Security has been in business since 2005.
