Trojan-Spy.Lindra not detected by Nod32 but detected by Spyware Doctor

Out of curiosity I downloaded Spyware Doctor starter pack from Google due to its great review from PC Mag. I scanned my computer using it and it turns out that there is a trojan in my computer that nod32 v3 didn't detect. Here's the report from Spyware Doctor quarantine:

Trojan-Spy.Lindra-Low
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\BITS#ServiceDLL
A malicious application that attempts to steal passwords, login details and other confidential information.

I didnt know how this happened. My Nod32 always updates almost hourly, I have Comodo Personal Firewall with HIPS on and Threatfire. I scan regularly with Indepth scan with Nod32 and Theatfire. The three of them didn't show any keylogging activity at all.

Due you advise that I should change all my passwords now? Thanks.

You've mentioned a reference to a registry key, but not file. Please send a log from ESET SysInspector (downloadable from ESET's website) along with any suspicious files you might have found to samples[at]eset.com with this thread's url enclosed.

 

I noticed that too actually in the result of the scan. There really was no file detected, only a registry key. There is also no file in the quarantine. Can a registry key by itself log and send data on the internet like the description from Spyware Doctor says?

I think this is more like a false positive on SD's side. Thanks.

 

Probably, this is a false positive. I had a similar case, when Spyware Doctor removed a reg key for my DVD software, simply due to its name matching the name a Trojan program assumes occasionally. I'd go by deleting that key and rescanning everything.
