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.
pop-up ads are caused by a browser plugin, which is typically installed on all web browsers that can be found on the system. In most of the cases, people download such browser plugins in a bundle with freeware and shareware, so you should start double checking each of freewares before its installation. The easiest way to prevent such infiltration, is to choose a Custom or Advanced installation method and then look for check marks that say that you agree to install and similar adware. If this plugin enters computer, it modifies several system settings and starts interrupting people with its ads. Please, never believe such notifications and never click ‘Download’, ‘Run Update’ or ‘Click to install now’ buttons! Otherwise, you may lead your PC to the infiltration of malware.
