Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading SpyRemover Pro to eradicate Malware for you (it should cut down the time to about 15 minutes).
Your CPU is an important part of your PC. But you already know that. You’re here because you want to know why your PC is running at 99% in your Windows Task Manager.
Fortunately, 99% CPU usage isn’t always a bad thing. It’s one problem that tends to look a lot worse than it actually is.
Troubleshooting – Open Windows Task Manager
If you want to troubleshoot your 99% CPU usage problem, then your first step should be opening Windows Task Manager. Go to the Processes tab and see which process is using all that CPU power.
In many cases, it will be an application called SVCHost.exe. SVCHost.exe is an official Windows process – so don’t worry about it being a virus.
In some cases, a sub-process of SVCHost.exe called uPNP (which lets you plug and play peripherals) will get stuck looking for compatible hardware. This causes 99% CPU usage. If you’re not trying to connect peripherals, disable that service by right clicking on it in the Services tab of Windows Task Manager.
If that works, then great! If not, then keep troubleshooting.
Run a virus scan
SVCHost.exe is a good program and an official Windows process. There’s a piece of malware, however, called SVHost.exe. See the difference?
SVHost.exe preys on your lack of attention to detail. You miss the ‘C’ and think it’s an innocent Windows process. In reality, SVHost.exe is a malicious program that actively steals your CPU processing power and bandwidth.
To fix this problem, run an antivirus scan with your chosen antivirus software.
Other possible reasons behind high CPU usage
-Too many background programs or active programs
-You’re running a resource-intensive PC game
-Your drivers are out-of-date
-You have problems and errors within your Windows registry
-You don’t have enough physical memory or virtual memory
-Your computer is not being properly cooled and is overheating
