Can a virus survive a reinstall?

Yes, most common viruses are wiped out by a full reinstall, but sophisticated threats like rootkits and bootkits can survive, infecting firmware (BIOS/UEFI) or other hardware, allowing them to reinfect the system even after a clean OS installation from a USB drive, making a full drive wipe and firmware update crucial for total removal.

Can a virus stay after reinstalling Windows?

That's because some sophisticated threats called rootkits and bootkits can infect your motherboard and the startup process. The malware gets right into the firmware, which remains even when the hard drive is wiped, and Windows is reinstalled.

Can a virus survive a system restore?

System restore points can inadvertently preserve malicious code, allowing viruses to survive reboots or basic removal attempts.

Can some viruses survive factory reset?

In the vast majority of cases, common viruses and malware will be completely removed after a factory reset. However, there are very rare cases where very sophisticated viruses may infect the BIOS or firmware, in which case even a factory reset may not be able to completely remove them.

Does restarting remove viruses?

Simply restarting your phone won't remove malware from your device but restoring your device to its factory setting will. However, before you factory reset your phone and wipe all your data, let's try three simple steps first.

Does shutting down a computer stop a virus?

Shutting down your computer stops active virus processes and prevents new attacks by cutting network connections, but it doesn't remove the virus; it just pauses it, as malware can easily reinstall or restart from your hard drive when you power back on. To truly eliminate a virus, you need to run antivirus software after disconnecting from the internet and possibly restart in Safe Mode to perform a thorough scan, or in severe cases, wipe the drive and reinstall your operating system, notes Quora and Steam Community. 

How do I wipe out a virus?

The best and easiest way to remove viruses is by using an antivirus solution designed to clean your system safely. If a virus is already on your computer, however, you may need to run this program under very specific conditions. If you're lucky, the virus may just be sitting in a program you recently installed.

Does factory reset stop hackers?

A factory reset removes most malware and hacker-installed software, acting like a fresh start, but it's not a guaranteed fix for everything; it won't erase sophisticated rootkits, malware on connected hardware, or the fact that your online accounts (like Google/Apple ID) might still be compromised, requiring you to also change passwords and secure accounts afterward. 

Will resetting a PC remove hackers?

Yes, a factory reset removes most malware and malicious software by wiping the device, but it's not a guaranteed fix for sophisticated attacks and doesn't secure compromised online accounts like Google or Apple ID. You must also change passwords, enable 2FA, avoid restoring infected backups, and secure your network/accounts to fully stop persistent hackers. 

Can a virus be permanent?

Once you have recovered from an infection, you have a good degree of protection against becoming infected again. But some viruses – for example the herpes virus – are capable of circumventing the immune system and setting up home permanently in the host cells.

How to permanently remove malware?

To remove malware, disconnect from the internet, reboot into Safe Mode, run scans with reputable antivirus/anti-malware tools (like Malwarebytes & Microsoft Defender Offline), clear browser data/extensions, and if needed, perform a full system reset, as malware can embed deeply, sometimes requiring a complete reformat for total removal. 

Will a factory reset remove a Trojan virus?

Yes, a factory reset (Reset this PC) effectively removes most Trojans and malware by wiping your drive and reinstalling a clean Windows, but it's not 100% foolproof; for maximum safety, choose the "Remove everything" option and ensure backups are clean, or perform a completely fresh install from a USB drive to eliminate deeply rooted threats like firmware/rootkit infections, which are rare but possible. 

Do computer viruses ever go away?

The only way to ensure that you eliminate a virus is to wipe your device and reinstall a new operating system on the machine: This is a good reason to practice good backup habits, because the process (called “reimaging”) eliminates everything on the hard drive (both the virus files and all of your files).

Can a laptop be tracked after a factory reset?

A laptop is very difficult to track after a factory reset because the operating system and tracking software are wiped, but some advanced hardware-level protections (like Intel Anti-Theft) or manufacturer-specific tools (like Apple's Activation Lock/Find My) can still work if the device connects to the internet and hasn't been fully bypassed, though standard Windows "Find My Device" usually stops working after a reset. A fresh OS installation or a hard drive swap usually removes software tracking, but some security features are embedded deeper in the firmware. 

Does getting a new computer get rid of viruses?

Malware is just software stored on your hard disk. All software, including malware, can be erased. In the worst case, a reformat and reinstall of Windows, your apps, and your data will get rid of malware, and is close to what you'd do if you purchase a new machine. Save your money.

Can police recover data after factory reset?

wear-levelling distributes data across the memory to extend the device's lifespan, meaning that even forensic tools capable of low-level access cannot reliably reconstruct overwritten or encrypted data post-reset.

Does shutting down a computer stop a hacker?

Yes, turning off your computer generally stops most hacking by removing its active connection, but it's not foolproof; attackers might use advanced methods like Wake-on-LAN to power it back on or exploit persistent features, so strong security practices like firewalls, antivirus, and patching remain crucial. A fully shut-down computer isn't running vulnerable software, but if malware is already installed, it could activate upon restart, so the real protection comes from proactive security, not just power cycling. 

Are there viruses that can survive a factory reset?

There are rare situations where viruses may remain on your device, even after a factory reset. If that's the case, you may have to try some other options, like scanning with your antivirus software and checking external devices for malware.

How to 100% get rid of a virus?

Does turning off WiFi stop hackers?

Yes, turning off Wi-Fi significantly reduces the risk of remote hacking by cutting the internet connection, making your device unreachable for many online threats, but it doesn't stop all attacks, as malware or physical access can still compromise devices, and turning off Wi-Fi doesn't prevent vulnerabilities in apps or OS, notes a Security Stack Exchange thread and a Reddit discussion. It closes the door on network-based attacks like sniffing data or connecting to fake hotspots but doesn't fix underlying software flaws or protect against phishing, viruses from downloads, or physical threats, according to The Prepared forum post and a Norton article. 

What's the deadliest computer virus?
