reported a startup error named "temp2". was correct to suggest checking for infection and removing the startup trace, but a single cleanup step can leave hidden persistence. The short checklist below shows a safer, more complete approach that removes the file, its auto-start entries and common leftovers without reformatting.

Start by isolating the PC (unplug or disable networking) and booting into a clean environment (Safe Mode or a rescue/boot scanner). Run up-to-date scanners such as Malwarebytes (https://www.malwarebytes.com/) and the Microsoft Safety Scanner (https://learn.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download). If the infection prevents normal scanning, use Windows Defender Offline or a rescue ISO before Windows loads ().

Locate the actual file and persistence points before deleting anything. Use Sysinternals Process Explorer to find the running process and its full path (https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer), then run Autoruns to view and disable all auto-start entries (services, Run keys, scheduled tasks) in one place (https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns). Common registry locations to inspect are HKLM\Software\Microsoft\Windows\CurrentVersion\Run and HKCU\Software\Microsoft\Windows\CurrentVersion\Run, and check Task Scheduler for unknown tasks. Submit suspicious files to VirusTotal for a second opinion (https://www.virustotal.com/).

After removal, reboot normally, re-scan, and verify no leftover entries remain. Back up the registry before manual edits and avoid untrusted removal tools. If the system still shows startup errors naming a missing file (a broken Run entry), that registry value can be deleted safely once the file is gone — but only after a backup. For persistent or complex infections, a rescue environment or professional recovery may be the safest option.
