Some malware types will disable your anti-virus and then block you from accessing security sites in an attempt to keep you from finding a way to remove it.
Are you finding any suspicious processes in Task Manager
? When you experience or encounter strange behavior, always check for new, unknown or suspicious processes that may be running on your system.
Determining whether a file is malware or a legitimate process sometimes depends on the location (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file. However, it then places itself in a different location on your computer. A file's properties may give a clue to identifying it. Right-click
on the file, Properties
and examine the General and Version tabs.
You can download and use Process Explorer
or System Explorer
to investigate all running processes and gather additional information to identify and resolve problems. These tools will show the process CPU usage, a description and its path location
. If you right-click on the file in question and select properties, you will see more details about the file.
