bitsadmin.exe - false positive as Trojan.Agent

I ran a Quick Scan of my system and it came up clean. But, then I decided to run a Full Scan (for kicks, since, in Malwarebyte's developer Bruce Harrison's recent interview on BestTechie.net he so strongly endorsed the effectiveness of mbam's QuickScan when he said he rarely runs the Full Scan) and it turned up a true, false positive.

The file that got flagged as Trojan.Agent was C:\Program Files\Support Tools\bitsadmin.exe - Microsoft's Background Intelligent Transfer Service (BITS) Administration Utility - that happened to be included in the Windows XP SP2 Pro Support Tools (KB838079) that I installed last year. A Google search turned up some info about a similarly named file, but with "!I!" prefixed on the file name.

After running the Full Scan again to generate the "/developer" log a second file A0094844.exe (in System Restore) showed up as well, flagged also as Trojan.Agent. What I want to know is whether this file is also a false positive, or actually a piece of malware (?????). Thanks for your input.

Here's my scan log:

This must already be being used by malware to bypass firewalls and is why it got added .

I hate files like this because fixing the FP will make the bad guys happy .

I am going to try something that should allow the file to miss detection but only if it is being used where it should be used from . There is nothing I can do about the SVI hit , that will still hit but because it is only in a restore point it wont be breaking the actual tool .

I will look into this some more and if it is causeing problems still I might have to delist it .
