Hello,

I recently had a teamviewer session who may have turned out to be shady. I saw him attempt to transfer a file, and I immediately terminated the connection and unplugged my ethernet cable.

Although I'm not concerned about the computer to which he attempted to transfer the file, it is connected to my home network, with systems I use for personal banking, etc.


The TV log file is too big to copy/paste, and I don't see an option to attach the file. I've provided below the section which I think logged the transfer. Help appreciated, thanks.

It's looks like it could be possible, from these lines...

I can't say whether there was something that successfully transferred, as there is no real confirmation of that; however, it does look like it could have happened. Looks like you allowed a file transfer, but it doesn't say the transfer ever started, or if it completed successfully; that's the only reason I can't say there definitely is/isn't anything that was loaded onto your computer. From the looks of things, it appears the file transfer server was shut down before any file transfer could be initiated; and that's definitely a good thing. I wouldn't worry too much, unless you have MBAM, HitmanPro, or your antivirus of choice comes up with something.

The log doesn't appear to give any information as to what the file being transferred was... so even if it was something malicious, the TV log wouldn't show it.

Are you trying to figure out if the file was a trojan/virus/etc.? If so, then I'd need some information about the actual file transfer, which it doesn't appear that TV logs that information.

I would like to know if a file was actually transferred.

Well you would see it you can see what the person is doing when you use teamviewer.

I use it often. Its not like other programs, where it cuts you off. So you have no idea what the person is doing

Well it doesnt say the name of any file anywhere. So your guess is as good as ours
