If it was me and I accidently infected OP's PC with malware that I didn't know was on my USB stick I would feel guilty for OP's loss and return the card.

Well, if I was sure that my USB stick caused a problem, may be I would do the same. But honestly, this story about accidental malware sounds like BS to me

I lived in not very safe area for a while. My car was cracked 3 times there, and things were stolen. I knew teenagers who did that, but I could not prove that they did. Reporting to police was useless, they could not do anything too. So, this is a situation when you can blame only yourself if hoodlums steal from you.

He's only returning the card because he was caught.

He was not caught, but he freaked out nonetheless. This is very suspicious, indeed.

I can't believe how people on here seem to want to go for the most elaborate scenario possible when it's obvious what happened. Anyway good luck to the op.

Believe it or not most of the other scenario's mentioned in this thread happen to people all the time, and aren't as elaborate as you might think.

so he's returning the card out of the goodness of his heart and despite the fact he lost not only what he paid for the card but also money from his own wallet.

If I believed the other person needs it more than I do and was not responsible, I would.

Besides, if he was the thief and he returns the card, what has he gained? Just the BTC, right? They would both be back to where they started - Kennji would have his card back and the thief would have just stolen his own bitcoins back.

I agree that he is the most likely culprit, I'm just pointing out details that show it isn't as "obvious" as it might seem.

He wasn't caught, he was accused.

Next time:

don't let others remote into their computers, you never know if their PC wasn't set up to steal from yours or whether it wasn't hacked by someone else
DISABLE autorun for all devices (cd, usb, hdd, etc.) so even if there is a virus on a USB memory (or any other device) it won't be able to start up and wreak havoc

A question,please.

reformatting hard drive and reinstalling Windows will remove keystroke logger,viruses AND rootkits?

thank-you

Well, I'd say yes, under the following conditions:
- You do a full reformat (ie not the the 'quick' one your OS might offer you during the install).
- You make sure your computer is offline during the process (pull the ethernet cable/disable the wifi card if any)
- You make sure you're not reinstalling the said malware in the process: Clean, official windows CD purchased in the store, legitimate software etc
- You immediately install an antivirus (try avast) and antimalware (try superantispyware)
- Using a different, safe machine or even better, someone with more IT experience than you, destroy/wipe any remove media you may have used on the compromised machine (usb sticks, etc)

Good luck!

He brought over his 3 year old daughter too and my son played with her while we did the transaction.

It's not the first time I hear about petty criminals using children has a decoy to their misdeed, but bringing one's daughter to conduct a scam that could have gone wrong very quickly is just shocking to me!

I remember watching an interview with a car thief serving time in prison who claimed he always took his toddler daughter along so as not to look suspicious.

Evidence against:

As Blazr mentioned, wallet stealers often wait until a significant amount triggers them into action and this address hardly had more than half a bitcoin in it before the day in question.
This person should have known that he would be the first suspected and that his victim could easily track him down.

Yes, if he is really a thief, he is very stupid thief. If he would wait for several days before cash out, first of all, OP would not suspect him, and second, OP could put a couple of btc more to his compromised wallet.

Note, when you reformat make sure that you write a new Master Boot Record to your drive, as malware can copy itself into it.

There is no guarantee that the guy actually stole his BTC. Many wallet stealers won't take the funds right away but will wait until a sizeable amount is transferred into the wallet before it cleans it out.

This is what I am talking about. There is 90% chance that he did stole btc from OP, but still 10% chance that he did not. There is no strong evidence.

I would say even less than 90%.

Evidence supporting this person was the thief:

He had unrestricted access to the computer.
The funds were transferred almost immediately after he left.

"Remove" may be the wrong word. reinstalling windows will disable the rootkit/keystroke logger?

Yes, but if it copied itself onto some low-level firmware then no. So for most intents and purposes a reformat is enough.

I meant, Kennji had no reason to let him touch his computer. I thought you were saying that it was the easiest way to give him the receiving address to send the funds to. I now see you probably meant it was the easiest way for a thief to gain access to his wallet and you're right, it is.

Yes, this is what I meant. Sorry for my bad English. After OP let the guy to log in to his computer, the guy could copy his wallet.dat by one click.

Technically, no. Like phones, computers have firmware. Anything you ever do, download, or see on your computer is embeded in your firmware. However, reformating can remove the virus from your computer rendering it useless, but that doesn't mean it is off of your computer for good.
