An Old Android Virus Is Reinstalling Itself Even After Factory Resets

Running a factory reset on a computer is an effective way to clear out a persistent virus or other malware you can't otherwise remove. Running a factory reset, also referred to as a Windows Reset or reformat and reinstall, will destroy all data stored on the computer's hard drive and all but the most complex viruses with it. Viruses can't damage the computer itself and factory resets clear out where viruses hide.

Factory resets don't remove infected files stored on backups: viruses can return to the computer when you restore your old data. The backup storage device should be fully scanned for virus and malware infections before any data is moved back from the drive to the computer. Some very rare viruses can find ways to evade factory resets: using a boot and nuke program and re-installing Windows from scratch can destroy such viruses.

Thank you so much for sharing about this app here. This is the only app that has blocked virus apps from getting installed by itself. I had used all sorts of antivirus, Malwarebytes, even did a factory reset to get rid of these viruses but they were getting install by itself. NoRoot Firewall is the only app that has resolved this issue. Thank you once again (I specially created this account just to thank you).

If the problem remains even after resetting the phone, what you have is a hardware problem. No virus can survive on the iPhone through a factory reset, so you should take the phone to an Apple store for servicing.

According to Symantec security researchers, the Xhelper Android Trojan is not only stealthy but also prolific. A Symantec report stated that the security company has "observed a surge in detections," of the malware that can both hide from users and download additional malicious apps. The most concerning aspect of Xhelper, though, is that it is persistent. How persistent you may be wondering? "It is able reinstall itself after users uninstall it," the researchers said, adding that the malware keeps reappearing even after users have manually uninstalled it. What's more, according to the research report, even a full factory reset cannot stop Xhelper from reappearing.

According to most Mac users, reinstalling macOS, Mac OS X, or factory resetting Mac always follows a system crash, computer slowdown, or even when Mac users need to erase their old Mac computer for sale.

It can help you scan the Mac hard drive or external storage device to find and retrieve all the files lost after reinstalling macOS or Mac OS X with ease, even if you never back up your files. The effectiveness of this method has been proven by its users. Don't hesitate to give it a try.

Earlier this year, a story made the rounds about a new kind of malware afflicting Android handsets. But it was this malware's pernicious nature that really made headlines, as it could even survive complete factory resets on afflicted phones. This insidious malware was named xHelper. At the time, we didn't know how it managed this impressive (but scary) achievement, but security researchers at Kaspersky have since dug into its inner workings, revealing an incredibly sophisticated system that installs itself to an Android phone's system partition, and even changes how the system works to prevent it from being "easily" removed.

File infectors are a common type of virus that spreads through executable files, usually within a network. If you reconnect to the same network that shares infected files, you can deal with the virus again shortly after the factory reset.

Disabling the Windows Security app service does not disable Microsoft Defender Antivirus or Windows Defender Firewall. These are disabled automatically when a third-party antivirus or firewall product is installed and kept up to date.If you do disable the Windows Security app service, or configure its associated Group Policy settings to prevent it from starting or running, the Windows Security app might display stale or inaccurate information about any antivirus or firewall products you have installed on the device.It might also prevent Microsoft Defender Antivirus from enabling itself if you have an old or outdated third-party antivirus, or if you uninstall any third-party antivirus products you might have previously installed.This will significantly lower the protection of your device and could lead to malware infection.

If you switch Real-time protection off, it will automatically turn back on after a short delay. This is to ensure you are protected from malware and threats.If you install another antivirus product, Microsoft Defender Antivirus automatically disables itself and is indicated as such in the Windows Security app. A setting will appear that will allow you to enable limited periodic scanning.

Most times, yes. That said, there are some exceptions. Factory resetting your phone will bring it back to its factory state (software-wise), so it should clean any harmful software like viruses, malware, etc. This may not be the case if your phone is rooted, though. Hackers can sometimes code malware into the system, and it can sometimes stick around after a full wipe.

This depends on your phone. Sometimes a factory reset will eliminate all information and allow thieves to use stolen or lost phones. That said, manufacturers like Samsung and LG are making it harder to access a phone even after a factory reset. This often requires entering a password, PIN, or confirming your identity.

However, while this built-in function brings us convenience, it also brings some hidden dangers. If you give your phone to a child, he accidentally resets your phone to factory settings without backup, you may be the risk of data loss. Imagine what to do if you encounter this situation? Is it possible to recover data after factory reset?

It is possible that a factory reset can remove viruses. It depends on the OS (operating system), the malware type, and how deep it is on your phone. However, factory resetting is capable of just wiping malware, which attaches itself to installation processes.
