Malicious
DRTCP.exe is a long-known TCP/IP tweaking utility flagged only by one engine as adware; tier-1 engines see no threat and it's likely safe from a trusted source.
de08e3d24dc3cafea0…b2e1c945b6The verdict, reasoned out.
Not a rules engine. The MT AI Engine reads every signal we collected, weighs them against history, and commits to an answer.
The file DRTCP.exe matches the hash of DrTCP version 0.2, a portable tool for tweaking TCP/IP parameters like MTU and RWIN directly via the registry. Our antivirus network shows just one detection from Zillya as Adware.DLBoost (a bundler), with 71 clean including all tier-1 engines like BitDefender and Kaspersky. It's unsigned but has positive reputation (32), common prevalence over 500 submissions since 2007, and no external threat intel hits. Behavior includes registry queries and network calls to Microsoft IPs, consistent with a network optimizer. A prior scan on our site also noted it as a legit network tool despite the flag.
- First submitted in 2007 (7002 days old) with positive reputation score of 32 and 504 community submissions.
- 17 tier-1 engines (BitDefender, Kaspersky, ESET, etc.) reported clean out of 76 total.
- No hits in MalwareBazaar, YARAify, or CIRCL threat intel sources.
- Identified as legitimate DrTCP TCP optimizer utility.
- Prior MalwareTips analysis recognizes it as a legit network tool.
- Zillya detects it as Adware.DLBoost.Win32.22, suggesting possible unwanted software bundling.
- Unsigned executable, common for portable tools but raises impersonation risk.
- Network tags include direct-cpu-clock-access, which can appear in both tools and threats.
- Sandbox behavior shows outbound connections to 20.99.* IPs (Microsoft Azure) and spawning wuapihost.exe.
- Mixed VT community comments mention possible worm traits alongside goodware tags.
Only run if you trust the download source, such as an official archive of Todd Laney's DrTCP; otherwise, delete it. Use a sandbox like Sandboxie for testing network tweaks.
