The first thing you need to do is to identify the process causing the high CPU utilization and where it is running from. While you can use Windows Task Manager
, it does not provide much information to trace the source of a questionable process.
If you're not finding any malware, there are tools which you can use to investigate running processes in real-time. By using them you can gather information to identify each process, where it is located and determine which one is consuming resources:-- These tools will provide information about each process, CPU usage, file description and its path location.
-- System Explorer provides a security check of running processing using their online security database when you first launch the program. If you want process the initial scan, press the "Start Security Check" button. Keep in mind, that the check is not a guarantee of what is or is not detected as malware. Further investigation is always recommended. At the Security Check page you can also check the file through the VirusTotal database by pressing the Check MD5 button.
Anytime you come across a suspicious file or one that you do not recognize, search the name using Google <- click here for an example
Or search the following databases:
If you cannot find any information, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to one of the following online services that analyzes suspicious files:
In the "File to upload & scan
" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons: Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable
I additionally have Registry Mechanic installed
The Windows registry
is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component
because it is where Windows "remembers
" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable
. For a more detailed explanation, read Understanding The Registry
. Not all registry cleaners are created equal
. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry
". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work. Not all registry cleaners create a backup of the registry before making changes
. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE
making any changes to the registry. Improperly removing registry entries can hamper malware disinfection
and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable
to removal tools. The usefulness of cleaning the registry is highly overrated and can be dangerous
. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results
Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily
could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great
