The client.
It seems to be an evolving problem. I first had it happen with 0.032.21 win 32 as soon as I installed it.
Since I did not pay much attetnion to where I got it from I deleted it.
I then checked that installs were from sourceforge and installed 0.3.22 and had it happen again then I tried 0.3.23rc1  which I had been using upto today. Then I suddenly had it removed by AVG again.
I have now tried 0.3.23 win 32 and as yet have had no problem but I suspect I will.

just AVG being aggressive. Protection and convenience are 2 ends of the same teeter totter when it comes to computer safety. You give up one to get the other, inverse correlation.

THis probably happens because botnets are probably distributing bitcoin in order to mine on zombie computers... and as a few people find the intrusion and send the unwanted files they found on their machine to AV labs for analysis, it results in bitcoin executables being flagged as malware.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper wallets instead.

That's because cracks and keygens are trojans, more often than not.

This is heuristic detection based on the code doing a number of things AVG considers suspicious. For one thing, it's receiving a lot of network connections on a port unknown to AVG. The thing that puzzles me though is AVG says it's injecting code. There are a number of legitimate reasons it might do that, but I can't figure out from the source why it would be doing that.

Those not having problems may have heuristic detection off or may have the threshold set higher. Heuristic detection will have a lot of false positives.

I don't know about AVG, but you may check the miner with http://www.virustotal.com/. Last time i checked, all the AV/malware scanners said it's clear Wink

I also had a flag from AVG.  This, though, was a flag for a PUP (Potentially Unwanted Program) raised on UfaSoft's bitcoin-miner.exe.  I'm assuming this was becuase of distribution by trojans dropping the miner on PCs to generate hashes for the distributer....

And because a corporation might not want its employees using their resources for mining...

I'm aware of someone who unexpectedly found bitc.exe *32 on their computer today and has submitted it to the major AV companies for analysis.

All I can say is that this is Bitcoin. I don't believe it until I see six confirmations.
