I'm fighting with problems with my computer (lenovo G780 on windows 764bit) for some time, and till now nothing helped. So I was hoping you guys can help me.


So in general, About 2 weeks ago i decided to clean my Windows after few years of using. I reinstalled it, as well with other programs and games I'm using. But from this moment some weird things have started.

- First of all the computer is working slower than before reinstallation.

- Secondly my antivir Avast premier is turning it self off, I mean its working in background but saying that im not secured and fire wall is turned off, I can turn it on but after some time its same story.

- Thirdly, right now I see that after I turn on the computer, and before i start using any kind of program, the svchost process is using more than 1 500 000 Kb of memory. 

- another thing is that windows update cannot install new updates. It download them, install and after reboot when it try to configure them it shows info, that it cannot be done and restart computer without upling the updates.


I was thinking it some problem with HDD so i tryed to run CHKDSK but it was unsuccesfull. So I removed the disk and went for another computer to do it from another windows instance. It was possible without any problems. Windows corrected all errors. I defragmented disk and serched for bad sectors, but everything was fine. 


Till now I tried to scan computer with avast (it cannot find anything and the avast cleanup scan stops at 99% and cannot move further regardless how much I will wait for it). Tried as well microsoft security essentials but it didn't found nothing. Downloaded Malwarebytes and scanned computer without any result.

I used even Webroot SecureAnywhere Endpoint Protectiona at my work, this one actually founded some infected files and removed them with success. But it didn't helped, computer is still slow and not working correctly.


I'm not sure what should I do now as its kind annoying to work on it, and I have no idea what should i do next.


Kind regards

Due to the svchost issue I feel best to repost .

We should get a deeper look. Please follow this Preparation Guide and post in a new topic.
Let me know if all went well.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/612914/windows-7-problems-with-update-avast-and-slow-working-computer/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic. Good luck with your log.
