Hi all

recently I upgraded my Kaspersky to Pure 3.0 and now suddenly when I run BFGminer.exe I can get to the mining.bitcoin.cz website and enter my worker and then my password but whereas before I would see line after line of calculations, I now see nothing. This has been happening for about two days. Any idea what is going on? Is it the Kaspersky? Is it something else? Please advise and thanks.
