Windows 10: Computer started to get more laggy

Hi all,

Does anyone know how to fix my problem?
One year ago, the computer was installed with Windows 7 and was upgraded to Windows 10.
About 3 months ago, the computer ran fine, and even the startup time was <10sec.
2 weeks ago, I got a virus and quickly deleted it with Malwarebytes and AdwCleaner.
I don't know why, but after that event, the computer quickly slowed down and right now, the startup time is 45 sec.

What happened and what is the reason?

Speccy Info:

My Upgrade Is Stuck On "Unfortunately it's taking longer than usual"

So I restarted my computer and it got to the desktop but it is really laggy and I can't get to settings

 

Application has been blocked from accessing graphics hardware

I'm inclined to agree with you. One of the previous listed fixes worked for awhile but then I started getting the error message again.

I went to the Nvidea website and downloaded their latest driver and it seems to have fixed the error issue, but it also seems to have caused my graphics to be more 'laggy' now as well.

 

Sorry for the bump, but anyone? Can somebody help?

 

Are the usual "maintenance" methods carried out regularly ?
Such as, Disk Cleanup, Disk Defrag, trim down the Startup list etc etc ?

 

For cleaning, I usually use CCleaner and yes, the disk is defragmented. I trimmed my startup list as soon as I installed Win10.

 

You may still have parts of the virus left on your computer. Removing a virus does not always work, some hidden files may remain. You may need to do a clean install.

 

What was the virus? You may have to do a clean install to make sure the virus is completely gone.

 

The virus was a trojan, MSIL exactly. It throwed me a lot of unwanted program installations etc.
But anyways, I decided I will go with a clean install.
Anyone who helped me, thanks. Problem solved.
