Although I’m not an expert on the subject, I’d like to share my strategies. Surely there are people here who know much more than I do and may have more effective methods, but this is what works for me:
On‑demand scanners: tools like KVRT (Kaspersky Virus Removal Tool) and ESET Online Scanner remain reliable and up‑to‑date for quick verification. They’re ideal as a second opinion when you already have a resident antivirus and want to make sure everything is clean.
Complementary approaches:
Restoring Windows from an image: fast and practical, in just a few minutes you have a clean system running (as long as you’re confident the saved image is truly free of infections).
Scanning from an external environment (rescue disk or similar): slower, but it provides extra peace of mind because it can detect threats that might survive a format, such as rootkits or persistence attempts in the boot process.
The first option is pure efficiency, the second is reinforced security. Depending on the level of risk one wants to assume, either approach can make sense… or even combining them: first a scan from outside, then a reinstall to ensure nothing remains hidden.
For rescue disks, alternatives like Kaspersky Rescue Disk, Bitdefender Rescue CD, or ESET SysRescue allow you to boot from a clean environment and are more effective against severe or persistent infections.
