I have read at least 10 different ways we should be reporting issues so I am just going to post this as I normally would and hope it helps.
With SB 2 Beta 3 [184.108.40.206 Build 20110804] If I have everything installed by default, specifically Live protection on, and open my browser it scans my Google Toolbar (GoogleToolbarUser_32) every time. Yes every time I open the browser it scans it and it takes about 20 seconds. Not sure if it is scanning any other toolbars etc... as I have several from installing MS Office but it does slow the browser down painfully. All passive protection is the best but I think for now I need to stop all the real time stuff. Any suggestions or have I helped in anyway? Please let ne know.
