The Lsass.exe service will load the processor (Windows 7): what is the reason and how to fix the problem?

Many users of Windows Vista operating systems and modifications above encounter an unexpected problem when the Lsass.exe service loads the processor (Windows 7 is not an exception), and to such an extent that it is simply impossible to work even with "native" OS services, not to mention Launching custom applications. What is the reason for this phenomenon and how to fix the problem, now we'll figure it out.

Service Lsass.exe will ship the processor (Windows 7): what is this process?

First, let's look at the service itself. It is a kind of user ID when logging in. The process itself refers to the components of determining the authenticity of the local security system and in the original is completely safe.

But why then in some cases the Lsass.exe process loads the processor (Windows 7)? Experts say that short-term bursts of computing power consumption can occur - this is normal. But the peak values of the loads can not be more than 50-60%. But is not it still a hundred?

You can, of course, try to disable the indexing service in the corresponding section, but there is little chance of success, since in most cases this situation is related to the virus effect.

Possible causes of excessive loads

In fact, the situation when the service Lsass.exe loads the processor (Windows 7 is taken simply as an example of the OS), can only testify that there is a virus on the computer. Usually it is a Trojan or a spy, disguised as a system process.

And more often than not, only one process involved in the load on the processor is not limited to. Incidentally, in the same "Task Manager" you can see the emergence of a large number of processes with the general designation svhost.exe. And this already says exactly about the virus effect.

Note: svhost processes can be four or five. If their number clearly exceeds this figure, this is the symptom of infection.

If Lsass.exe loads the processor (Windows 7), what should I use first?

Thus, it is not difficult to guess that when such symptoms appear, you should immediately check the system with an antivirus scanner, but not the one installed in the system. In addition, use third-party utilities preferably portable type.

You can find the virus yourself. If it became apparent that the Lsass.exe service is loading the processor (Windows 7), in the simplest version, you should look at the original executable file. It should be located exclusively in the System32 directory of the main system folder. At the same time for versions of Windows Vista and higher, its size is 56.5 Kb. If the search identifies any other components (perhaps even hidden ones) in a different location and with a different size from the original, such objects must be removed immediately. If the system prohibits deletion, you must restart the computer in safe mode and try to delete again. It is very likely that the properties will need to remove the attribute that indicates read only.

The most suitable tools

But the most important problem, judging by the feedback of Internet users, is that not all antivirus protection tools can detect the presence of this threat on the computer. For example, the same Avast does not give a result. In general, free scanners are not recommended for system testing (only because of their limited capabilities).

But back to the situation where the Lsass.exe service loads the processor (Windows 7). What to do in this case? It is best to ask for help from specialized utilities, among which you can note the following:

• AdwCleaner.
• Anti-Malware.
• Kaspersky Anti-Ransomware Tool.
• FixSecurity and others.

These programs are precisely good because they have a narrow focus on identifying threats of a strictly defined nature. However, only these utilities list is not limited. If you want, you can search for something else similar.

Troubleshoot Google Chrome browser problems

There is another type of situation when the Lsass.exe service loads the processor (Windows 7). Quite often this is due to Internet surfing, when Google Chrome is used as the main browser. It is still not clear why this is happening, but the fact remains.

At least, judging by the reviews, the usual reinstallation of the program helps. Perhaps, too many installed extensions play a role here, which influence this behavior of the system. After reinstalling the browser, if there is a need to use additional add-ons, it is better to install them or turn them on alternately, rather than all at once.

Instead of an afterword

As you can see, excessive load on the processor can be caused by several factors. In the case of viruses, it is best to use the above utilities as the main method of fixing the problem, but the prerequisite is to update the databases to the actual state, otherwise the threat may not be detected. As for the use of other anti-virus programs, some users claim that they do not define threats. In addition, some applications like the free version of AVZ do not work correctly with 64-bit systems, although the manufacturer claims the opposite. The same free packages are very often limited in basic functionality or even do not allow updating their own databases.

Cases of problems with the browser Google Chrome can be called a single, however they still meet. In order not to lose your own data, before deleting the browser, you can export the bookmarks to a file, then quickly restore them. And it is desirable to delete it not by its own uninstaller, but by more powerful tools, for example, the iObit Uninstaller program, which removes not only the main files, but also the remaining files of the program, as well as keys and entries of the system registry.

But in general, the problem should be treated in the same way as the usual elimination of virus threats. And the situation itself is not out of the ordinary. Although, if the suspicion of the virus was too late, personal data may be in danger. So, as soon as you see the first symptoms, you must immediately take drastic measures. In any case, it is necessary to take care of the security of your own computer in advance and install at least some kind of shareware antivirus. A good solution is to install the ESET Smart Security package. True, the activation of this software product will have to be produced every month. But the keys or "rectifiers" of licenses can be searched even on the official Russian developer resource, so this is not a problem. But the risk of catching the virus will decrease very significantly. It goes without saying that you can install other similar applications, especially since for all of them you can update databases several times a day.
