HP ProBook 6560b does not open Internet Explorer. When it reboots, it shows several .exe errors, including, but not llimited to, csc, iexplorer, Rundll, netsh, LZMA_EXE and DPAgent. I ran CCleaner and Malware Bytes several times. I also did a System Restore, which failed, even when it ran on Safe Mode. Whatever it is that's attacking my laptop it's giving me a headache. Otherwise, machine runs OK.
