CircuitryAg.exe Pop-Ups: Check What Keeps Starting

If CircuitryAg.exe keeps opening an error window after you ran an untrusted ZIP download, keep detected files quarantined and check what is launching it. Replacing a missing sqlite3.dll is the wrong first step: it could make an unwanted program work again. A failed launch can leave a noisy startup entry behind, while a separate component may still be active. Compare the exact startup command and fresh scan results before deciding which situation you have.

If you already ran the download, disconnect the affected PC from the network and use a clean device for passwords, email, and payments while you investigate. Closing the pop-up alone does not resolve that exposure.

What is CircuitryAg.exe?

The name appears in public reports of persistent Windows error pop-ups after suspicious downloads. In one detailed report, the user described a Trojan:Win32/Wacatac.B!ml detection involving C:\ProgramData\InProcSvr32\sqlite3.dll, a startup entry named CircuitryAg, and an error that returned after reboot. That is a reported symptom pattern, not a confirmed identification of every file using this name. [1]

The available reports do not establish a single malware family or prove what a particular PC executed. If your security alert specifically says Wacatac, use the Wacatac.B!ml detection guide for the alert itself. Here, the useful question is narrower: what keeps asking Windows to start CircuitryAg.exe?

Why does the pop-up mention sqlite3.dll?

A program can depend on a DLL to start. If that dependency was quarantined, deleted, or is otherwise unavailable, a surviving startup command can still try to launch the program and produce an error. This is one possible explanation for the reported sequence; it does not establish which component was malicious.

The reported messages include:

“The code execution cannot proceed because sqlite3.dll was not found.”

“The application was unable to start correctly (0xc0000906).”

The missing-DLL message describes a failed dependency lookup. The error code alone does not identify the malware, explain why access failed, or show whether another payload ran earlier. Also, a DLL filename by itself does not tell you what is inside that copy.

Do not download a replacement DLL, restore the quarantined copy, or add an antivirus exclusion to silence this error. Windows loads DLLs from application and other configured locations; supplying a file to an untrusted launcher can change what code it runs. [3] First establish whether the parent program belongs on the PC.

Save the details before changing startup settings

1. Record the alert. In Windows Security, open Virus & threat protection > Protection history. Save the detection name, affected-item path, time, and action. Distinguish a new detection from an old entry you are reopening.
2. Record the pop-up. Note the exact executable spelling and whether it appears immediately after sign-in, several minutes later, or after opening a particular app.
3. Record the download. Keep its source URL, filename, and approximate execution time in your notes. Do not restore a deleted ZIP or run it again to reproduce the error.
4. Keep quarantine intact. If a scan requires a restart to finish remediation, save your notes first. Avoid repeatedly deleting history or files before you have enough information to compare the next result.

Find the command that starts CircuitryAg.exe

Start with Task Manager > Startup apps. For a fuller view, Microsoft Sysinternals Autoruns lists startup locations, scheduled tasks, and services. Its official download is in the References below. [2]

1. In Autoruns, look for CircuitryAg and the path shown in your alert. Check the Logon, Scheduled Tasks, and Services tabs.
2. Save the entry name, complete command, startup location, and publisher/signature information. Use Properties and Jump to Entry to inspect the target.
3. If the entry clearly points to the unwanted download or the exact suspicious path, uncheck that individual entry to disable its automatic launch. Keep your record so the change is traceable. Do not disable unrelated entries based on their color or an unfamiliar name.

The public report named the current user’s Run registry key. A Run entry starts a command at sign-in, but it is only one possible launch point. If you need help interpreting a command that runs a script or another executable, follow the suspicious startup app checks before changing it.

The directory C:\ProgramData\InProcSvr32\ is a clue to compare with your own alert, not a deletion rule. Do not erase ProgramData, remove unrelated DLLs, or delete COM registry entries just because their names look similar.

Compare what changes after cleanup and one restart

Save a “before” note with the exact command and detection time. After scanning and completing the requested remediation, restart once and compare the same items. This separates three different outcomes:

1. The error returns, but the suspect file is absent

The same error returns, the suspect file is absent, and there is no new detection. An old command or another launch point may still be trying to start a missing component. Find the command responsible; the pop-up alone does not prove that the quarantined file came back.

2. An entry, file, or detection returns with new evidence

A disabled entry becomes enabled again, a new command appears, or a file/detection returns with a new timestamp. Investigate recreation or another active component. Keep the PC isolated and save both versions of the evidence for a trusted technician. Repeatedly removing the visible entry is not enough.

3. The entry stays disabled and the pop-up stops

The entry stays disabled, the pop-up stops, and current scans find no further detections. The visible startup symptom is resolved. If the untrusted download ran, still complete the account checks below; stopping a launch does not undo earlier activity.

Scan for the component that keeps launching it

A security tool may quarantine a visible DLL while a startup instruction, scheduled task, service, or another bundled component remains. That possibility matters when a pop-up returns after sign-in or a new file appears after removal.

After saving the details and disabling a clearly identified unwanted launch entry, run a full Gridinsoft Anti-Malware scan. Review the findings, remove confirmed detections, complete any requested restart, and compare the startup entry and scan results again. Obtain the software from the official site; if needed, use a clean device to download it rather than keeping the affected PC online for normal browsing.

A scan can help locate malware and persistence. It cannot recover stolen credentials or establish that the computer was never exposed.

When to secure accounts or reinstall Windows

If you executed the suspicious download, treat account recovery as a separate task. From a clean device, change important passwords, revoke active sessions, and review recovery addresses, sign-in activity, and payment activity. Start with your main email account. The post-download account recovery guide explains the sequence. These precautions do not mean CircuitryAg.exe has been conclusively identified as an infostealer.

If fresh detections or launch entries continue to return, security settings have changed without your involvement, or you cannot establish what ran, a clean Windows installation may be the more dependable recovery choice. Use the clean-install USB workflow to prepare installation media on a clean device and preserve only necessary personal data. Do not carry the suspect installer or a complete browser profile into the new installation.

If the file was blocked before you ran it and there are no other symptoms, avoid assuming that every account was compromised. Preserve the alert, keep the file blocked, and base further action on what actually executed and what current checks find.
