pic1234.exe: the I-Worm.Newpic worm file and how to remove it
pic1234.exe is installed and used by the worm I-Worm.Newpic. It launches the parasite, loads the main components of the malware and runs a destructive payload. It is a significant part of the worm but can also work as a stand-alone threat. Do not run it. Delete the file by hand, which also ends its process.
Prefer to do it yourself? The manual steps follow.
pic1234.exe is a worm file. The old report ties it to I-Worm.Newpic and says it starts a same-named background process that performs harmful actions for as long as the file exists on the PC.
The old report adds that, rarely, a file with this name has been found that was not an infection. So check where it sits and what it is before you delete it, but do not run it to find out.

What pic1234.exe does
pic1234.exe is an executable that is responsible for launching parasites, loading the main components of malicious programs and running a destructive payload. The old report calls it a significant part of a dangerous parasite that can also work as a stand-alone threat.
The file is installed and used by the worm I-Worm.Newpic. When it runs, it usually starts a process with the same name, which works silently in the background and carries out the harmful actions. The process stays active for as long as pic1234.exe is present in the system.
Removing the file ends the process immediately and prevents it from starting later. This is why the report asks for manual deletion of the file, not only for stopping the process.
The old report also says that, in rare cases, the presence of a file with this name does not mean infection, because it can be a file installed by harmless software. A file with this name is not a Windows component, so examine it thoroughly before deciding.
About .exe files. An .exe file is a program. It runs as a process you can see in Task Manager, so its name, folder and publisher are what to check.
How it gets on a PC
The old report says only that the worm I-Worm.Newpic installs pic1234.exe. The “I-Worm” prefix in that name marks an e-mail worm in the naming scheme some antivirus vendors use, so it most likely reached PCs as an attachment, but the report does not describe the route and none is claimed here.
In general, worms and their files reach Windows through malicious e-mail attachments, pirated installers and cracks, and removable drives. If pic1234.exe turned up on your PC, think about the last unfamiliar attachment or download you opened.
How to find it
Check for both the file and the process of the same name.
- Look for the process Press Ctrl + Shift + Esc, open the Details tab and look for pic1234.exe. Right-click it and choose Open file location to see where it was started from.
- Search for the file Search the disk from Command Prompt for every copy.
dir /s /b C:\pic1234.exe - Check the signature Open the file’s Properties and look at Digital Signatures and Details. A worm file is normally unsigned and has no real company name or description.
- Check what starts it Run Autoruns from Microsoft Sysinternals and look at the Logon, Services and Scheduled Tasks tabs for entries that point to pic1234.exe.
- Scan the file Right-click the file and choose Scan with Microsoft Defender, or run a full scan from Windows Security.
The name alone is not proof, since the old report admits rare harmless cases. An unsigned file with this name in a user, Temp or Downloads folder, next to a running process of the same name, is treated as the worm.
How to remove pic1234.exe
Because the process lives only while the file exists, deleting the file is the key step. Do it first if you can; scan afterwards for the rest of the worm.
- Delete the file Note the folder of pic1234.exe, end its process in Task Manager (Details tab) if it will not delete, then delete the file and empty the Recycle Bin.
taskkill /f /im pic1234.exe - Remove the startup entry In Autoruns, delete any entry or scheduled task that pointed to the file.
- Run a full Microsoft Defender scan Open Windows Security > Virus & threat protection > Scan options, choose Full scan and remove everything it finds. The file is only one part of I-Worm.Newpic.
- Run Microsoft Defender Offline scan In the same list choose Microsoft Defender Offline scan. The PC restarts and scans before Windows loads, which catches components that hide while Windows runs.
- If it will not delete Restart into Safe Mode (Settings > System > Recovery > Advanced startup > Restart now > Troubleshoot > Advanced options > Startup Settings), delete the file there and scan again.

Questions people ask
What is pic1234.exe?
pic1234.exe is a file installed and used by the worm I-Worm.Newpic. It launches the parasite, loads the main components of the malware and runs a destructive payload. The old report calls it a significant part of the threat that can also work as a stand-alone threat, so a copy on your PC should be treated as malware.
Should I run pic1234.exe to see what it does?
No. The file launches parasites and runs a destructive payload, so running it on a PC you use is the way to get infected. If you must study it, use a virtual machine with no personal data. To decide whether it is genuine, look at its folder and digital signature instead.
How do I stop the pic1234.exe process?
Delete the file. The old report says the process stays active while the file is present, and that removing the file ends the process at once and stops it running later. End the process in Task Manager first if Windows will not let you delete the file, then delete it.
Can pic1234.exe be a harmless file?
Rarely. The old report says the file can sometimes be installed by harmless software, so its presence alone does not prove an infection. Such cases are quite rare. Check the folder, the digital signature and a Microsoft Defender scan result before you delete or keep it.
Is deleting the file enough to clean the PC?
It stops this file and its process, but it is not a full clean-up. The worm can have installed other components, and the old report says pic1234.exe loads the main components of the malware. Run a full and an offline Microsoft Defender scan after deleting, and check Autoruns for leftover entries.
What if I cannot delete pic1234.exe?
End its process in Task Manager and try again. If Windows still blocks it, restart in Safe Mode, where the worm does not run, and delete the file there. Then run a full and an offline Microsoft Defender scan to remove the related components.
