Malware - short for malicious software - is an umbrella term that refers to any software program deliberately created to perform an unauthorized and often harmful action.
Viruses, backdoors, keyloggers, spyware ,adware, rootkits, and trojans are just a few examples of what is considered malware.
A few years ago,it was once sufficient to call something a 'virus' or 'trojan horse', however today's infection methods and vectors evolved and the terms 'virus and trojan' no longer provided a satisfactory definition for all the types of rogue programs that exist.
I have tried everything in your article, I have a laptop, Lenovo G570 Windows 7 x64 running IE11, upgraded from IE10, same issue. If I do not run IE without “Run as Administrator”, it is extremely slow, the circle of death run round and eventually you get to the page, in the application event log you receive event 1000 and 1001, fault bucket errors, appcrash errors, and . I have checked using four different malware and rootkit programs, it is clean. If I run as an administrator, no errors and runs fine. Next I will downgrade to IE9 or even IE8, or my last choice is a total reload of Windows. I have many years of IT experience being an IT manager, but this one is kicking me a bit, thanks for any suggestion.
