Is Linkbar_1_6_9.zip safe?
This file is a legitimate open-source desktop utility known as Linkbar, and the single low-trust engine detection is a characteristic false positive for this type of system-integrated software.
Our analysis indicates this file is a legitimate desktop toolbar utility. The single detection from a low-trust engine is inconsistent with the clean reports from all tier-1 antivirus providers and the file's long-standing history of public availability.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Our analysis indicates this file is a legitimate desktop toolbar utility. The single detection from a low-trust engine is inconsistent with the clean reports from all tier-1 antivirus providers and the file's long-standing history of public availability.
The file is a ZIP archive containing the Linkbar desktop utility, a well-documented open-source project. The single malicious detection by a low-trust engine is a common occurrence for utilities that interact with the Windows shell. All tier-1 engines analyzed the file as clean. Furthermore, the file has a long history of public submissions, which is inconsistent with malicious software. The sandbox behavior, while triggering heuristic flags for process interaction, is consistent with the expected operation of a desktop toolbar.
What We Detected
The file is a ZIP archive containing the Linkbar desktop utility. Our analysis shows that the single detection by a low-trust engine is a false positive. All tier-1 engines in our network have cleared the file.
Threat Behavior
The sandbox analysis identified heuristic flags related to process interaction (MITRE T1055). These behaviors are expected for a desktop toolbar utility that manages shortcuts and interacts with the Windows taskbar and shell. No malicious network activity, dropped malicious files, or other indicators of compromise were observed.
What To Do Now
This file is considered safe for use. As with any software, ensure you are downloading it from the official project repository or a trusted source to maintain integrity.
Where this verdict could be wrong1 caveat
- MaxSecure flagged the file as 'Trojan.Malware.300983.susgen', but this is a single low-trust engine detection without corroboration from any tier-1 engines.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 17/17 tier-1 engines reported clean
- Common, long-standing utility (first seen 2021)
- No malicious network activity observed
The file is safe to use. Continue to keep your endpoint protection enabled.

The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
