|I recently encountered a problem when trying to install the new IE8 browser. I recieved an error stating that the sfc.dll was missing and IE would not install. I researched the issue and then tried to replace the sfc.dll file in the system files. This then presented me with another issue, a new error - "The ordinal 7 could not be located in the dynamic link library sfc_os.dll". This occurs when I try to open certain software, usually internet applications. For example windows messenger, windows live mail. However the applications will run.|
Windows update will not run and it just hangs the OS or even crashes completely. Windows defender will also not run. I get an error that says "windows defender encountered an error: 0x800700b6. The operating system cannot run %1"
I am concerned that this may indicate I have a trojan. I have ran my Norton Anti-virus software several times and also used the Microsoft Malicious Software Detector.
I read that if Windows update cannot be activated this could be a sign of malicious software running on my machine.
I am running Vista on my home machine that is linked over a wireless connection to the internet.
As you can see there are loads of problems and I just can't seem to understand what is going on. Any help would be much appreciated!
