Make sure you add bitcoin.exe to the “Excluded processes” list, not only files for scanning.
See this thread: topic 35
I submitted bitcoin to the MS Security Essentials developers back then with explanation of the problem. They responded they would check the performance concerns, but I don’t know what they’ve made of it.
Okay I am not sure if I should add this here. But It has been a bit over three days since I installed and have had bitcoin running 24hrs a day. The first day in under 15hours it had generated some progress and sent out the 5 failed transactions. Now it has been approximately 72 hours. There has been no activity at all. My client reports that it is working on the current block as noted by the page someone here setup to show the length of the current computations. Is this common can it take days and weeks to generate even one bitcoin. I am not a programmer at all. I read the whitepaper and other stuff but much of it just evades me.
u can’t generate just 1coin, u’ll get 50coins for completing 1block, or you dont get them if someone else was quicker.
a few days ago i was able to generate 50coins in less than a day, but the difficulty to create a block tripled since slashdot and so did the time to generate coins.
so yes, its pretty usual to take “forever” to generate a coin, at least expect it to take a few days, to get your first 50coins, depending on how much cpu-power u’v got to spare.
Microsoft Security Essentials Live Protection is blocking your communication with the network. You have connections, which tricks Bitcoin into thinking it’s connected, but they are silent because the data is being blocked.
You need to make bitcoin.exe an excluded process in Live Protection.
This is becoming a common problem. Someone should write this up in a pegged thread.
The message “Warning: This block was not received by any other nodes” occurs when Bitcoin broadcasts a block, but nobody confirms they received it. The warning is there just for this kind of situation, where for some reason you have connections, but they have gone dead and nobody can hear you. Your block will never become valid because nobody received it.
