Before You Start
Prepare a clean environment by closing all browsers and saving work. Ensure you have an active internet connection for updates, but disconnect from networks after the initial scan if you suspect network-based threats. Create a system restore point as a precaution. Avoid downloading software from untrusted sources. If possible, use a second device to verify download integrity. Typical cleanup time ranges from 30 minutes to a couple of hours depending on system speed and infection depth.
