I have or possibly had the ABOUT:BLANK malware problem. I took a lot of actions getting rid of the malware BHO dll that puts the the keys in the register and loads the SP.HTML page but I could not figure out how to find the malware dll that installs the BHO dll until I saw your post. I thought this was the solution so I traced your path HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows and guess what I don't have a windows under current version. I said oh well and searched the register for appinit_dll keys and guess what-- it has none. Do you have any idea how I could have this malware problem but without the indicators you describe. Earlier today this problem struck--I could not open the Iexplorer and than suddenly it opened at least 10 Iexplorer windows and my firewall router started to blink so fast I thought it was going to bounce off the table. I unplugged it. After unplugginig and rebooting I took all the Hijackthis and Adware actions to clean out all possible register entries and delete the DHO dll. I plugged back in the router and have been working okay since then (8 hr's ago). I am wondering that by unplugging and re-plugging my router the router will assign new local IP addresess on my LAN and this prevents the Malware from accessing the computer which had the malware problem. Any ideas on this or any other way I can find the hidden malware dll.
