Questions & answers

Short answers to the 7 questions people ask most about this file.

Is TCPOptimizer.exe safe?
We found nothing harmful in TCPOptimizer.exe. 2 of the 71 antivirus engines that checked it flag it; after weighing the other evidence we treat those alerts as false alarms. Run it only if it came from the developer's own website or an official app store.
What is TCPOptimizer.exe?
TCPOptimizer.exe is a Windows program, about 684.0 kB. Its version information says it is “SG TCP Optimizer” (SG TCP Optimizer Application). Version information is written by whoever built the file, so it is a claim, not proof of who made it. VirusTotal first saw it on Jan 9, 2021.
How many antivirus engines detected TCPOptimizer.exe?
2 of the 71 antivirus engines that checked it flag TCPOptimizer.exe, including Trapmine and VBA32. We weigh which engines flagged it and what else the scan found, not just the count.
Has TCPOptimizer.exe been seen before?
This exact file is listed in MalwareBazaar, a public malware database, first listed on Jan 24, 2024. MalwareBazaar accepts automated uploads; the Safe rating weighed that listing against the other evidence and does not rely on it.
What is the SHA-256 hash of TCPOptimizer.exe?
The SHA-256 fingerprint of TCPOptimizer.exe is 0a49dc0d2ce725af347df632539b70afcfd22b38e285920b515143332a5511e9, and its MD5 is d8292150c8ce862a97a923318df07805. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
Is it safe to run TCPOptimizer.exe?
We found nothing harmful in TCPOptimizer.exe. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of TCPOptimizer.exe?
This report reflects the scan on Oct 19, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
