Ping.exe is a command line utility available in Windows OS. It was created to verify whether a specific computer on a network or the Internet exists and is connected. The legit utility runs from C:\WINDOWS\system32\. Normally, it shouldn't cause any problems. Unfortunately, there are malicious programs posing as Ping.exe and chewing up your CPU usage. You can stop Ping.exe using Task Manager but it will re-spawn within minutes and cause the same 100% CPU usage as before.
In our case it was the notorious TDSS/Alureon rootkit. You can remove this rootkit easily using TDSSKiller. It is also worth mentioning, that this rootkit was hiding the presence of Trojan droppers. Such combination made our computer act as a zombie, not to mention that cyber crooks could easily steal every bit of information from our system. If you are in a lot of trouble with 100% CPU and pop-ups that are contently asking your permission to make changes to the system or download files from the internet, please follow the removal instructions below.
