Gartner Magic Quadrant for Cloud Infrastructure as a Service(Worldwide)(2018,2017,2016,2015,2014,2013,2012...)

In the context of this Magic Quadrant, cloud compute IaaS (hereafter referred to simply as "cloud IaaS" or "IaaS") is defined as a standardized, highly automated offering, where compute resources, complemented by storage and networking capabilities, are owned by a service provider and offered to the customer on demand. The resources are scalable and elastic in near real time, and metered by use. Self-service interfaces are exposed directly to the customer, including a web-based UI and an API. The resources may be single-tenant or multitenant, and hosted by the service provider or on-premises in the customer's data center. Thus, this Magic Quadrant covers both public and private cloud IaaS offerings.
2018

Basic Procedures to Troubleshoot an Infected Computer

Today received a report from user, computer is slow and seems have been infected with unknown virus or malware. No special symptoms except slow.

1. Check task manager and resource monitor

There is a process smss.exe which description is "Microsoft ? Console Based Script Host " using almost 75% CPU all the time.

From task manager, I found system was rebooted a couple of hours ago at very early morning and user was not around.

Also, no matter how you ended this process, it will come back in 10 seconds and take your CPU away and use about 4M your memory.
