One of the most popular Android emulators on both Windows and Apple OS, BlueStacks allows you to run mobile apps and games on your desktop. It’s also a piece of software that sometimes triggers antivirus alerts, making a lot of us ask the question: Is BlueStacks safe? Here’s a detailed, expert look at the security, privacy and performance aspects of iOS 12 before filing on the install.
Is BlueStacks Safe and Legal?
So basically BlueStacks is safe to use when you download the official version of it. The software is more than 10 years old, made by a company that is based in the United States (BlueStack Systems, Inc.) and it is used by gamers and power users anywhere. The company publicly touts over a billion downloads and hundreds of millions of users, and its Windows installers are code-signed — a basic, fundamental signal of legitimacy.
The emulators themselves are not the biggest security risk; it’s where you download them from. Third-party mirrors are sometime bundled with adware or malware. Only download from the developer’s site, confirm the publisher name in the digital signature in the installer, and — if you’re paranoid — scan the file with a trusted engine or multi-scanner service before you start it.”
Why Does Antivirus Block BlueStacks?
Lots of security suites rely on heuristics to watch for the installation of anything that installs drivers, messes with graphics, or delves into virtualization. BlueStacks speeds up your Android gaming through hardware-assisted virtualization (Intel VT-x, AMD-V) and low-level API hooks, a shady-sounding technique that can be used to harm computer users as well as help them, so some of the automated systems can get a little suspicious even when it’s doing nothing wrong.
Security experts, including the masterminds behind such frameworks as MITRE ATT&CK, explain that adversaries sometimes exploit virtualization to avoid detection. That context serves to explain the occasional false positive. A warning does not develops a malware – specially when the installer is the proper one signed and the same that the official one.
If your antivirus prevents you from installing Big Tech Defense, please seek information in the document provided by the vendor. The label “PUA/PUP” (or “heuristic”) is typically used to indicate suspicious function, rather than a known malicious signature. You can also send signature file to your antivirus vendor or submit to Virus Total for re-classification, if you suspect the file is incorrect detection (a false positive).Notes: [1] You can make your own custom blocks by going to the Firewall settingspan over to Packet Filterand click Add Drop Rule [2] Development has identified false positives generated by the latest definitions of McAfee, which are released on the 2nd Januaryfrom Virus Scan Enterprise.
Performance and system resources
Emulation is demanding. BlueStacks will run smoothly on modern computers equipped with Virtualization Technology and the computer’s firmware (BIOS/UEFI) isn’t explicitly disabling such features… unless you are running a resource hungry game or a whole bunch of instances. The emulator can hog quite a bit of CPU, RAM and GPU on older hardware, and you might find your laptop’s battery charge just doesn’t last very long when it’s running.
Best practices get VT-x/AMD-V enabled, give enough number of CPU cores and memory in BlueStacks settings, disable any high frames when unnecessary, and close all the unused app instances in BlueStacks. If you notice spikes that never go back down, check the processes within Task Manager and Resource Monitor. In spite of these, accusations of obscured crypto-mining have not been back by evidence that I’d call convincing; your resource use should be a function of the kinds of workflows that you run.
Signing in to Google: security and privacy
You’ll need to sign in with a Google account to get to the Play Store, as you would on any Android device. The login is facilitated through Google’s actual services, and we haven’t seen any credible reports showing BlueStacks collecting login details. Nonetheless, treat it as you would any third-party device: turn on two-factor authentication, use Google’s Security Checkup to see if any unrecognized devices have been accessing your account, and get notified when someone signs in.
Nervous about getting an email from Google saying there is a “new device” on your account? When you log into an emulator, it will create a device profile (BlueStacks has historically emitted profiles similar to OnePlus in nature, by default) on your account’s device list. Privacy-conscious users will often set up a second Google account for emulators; the risk and potential purchases stay compartmentalized, but any purchased apps won’t transfer over from your main account.
BlueStacks makes money through ad sales and app recommendations, according to the company’s privacy disclosures. It tells users it doesn’t sell personal identifiable information but collects telemetry, including usage, installs and crash reports. You also can rein in data collection by opting out of personalized ads where it is available, pruning analytics permissions in the app, and tightening OS-level privacy settings. Periodically review data practices — polices can be updated.
How to safely install BlueStacks: The quick checklist
– Download from official sources only, not from third-party mirrors.
– Right-click the installer and check the digital signature for BlueStack Systems, Inc.
– Turn on hardware virtualization in BIOS/UEFI and in Windows features go marking it.
– Be sure to update your OS, GPU drivers, and emulator in order to ensure you are protected against security issue.
– When possible use a normal (non-admin) Windows user account for daily work.
– Secure your Google account with 2FA and check up on device activity before the first sign-in.
Bottom line
While BlueStacks is assumed safe for your PC when downloaded from the official BlueStacks site and used with reasonable secure practices, depending on your needs, you might take a different view. Anticipate that resources may be eaten up during gameplay and multi-instance runs; not so they can be used to perform covert actions. If you’re looking to run Android apps on your computer, BlueStacks is the way to go, and the average home user probably won’t notice anything to complain about with the versions of the app that require you to deal with ads.
