I am sorry to hear about that problem. My name is***** am a tech expert with 17 years of experience and will help you as good as I can.
May I remotely connect to your computer, so that I can directly analyze and resolve the problems + tune-up the computer for you while you can relax and watch me doing it on your screen? This is a very safe option too because JustAnswer is an A+ accredited business with the BBB, you will be watching your screen, and we will chat there as well so that you will always know what I will be doing next while fixing the problem.Should you not be interested in this option and would like to solve the problem via this text-based chat instead, just let me know.

Thanks for your patience and best regards,
I think it is a combination of many things, might still be a virus, might still be malware on it, there might be a process (from whatever program) that has a memory leak which increases to great extends after a few hours, without seeing the computer, I honestly cannot help you at all, that is just the truth. I am an expert for exactly such cases though and would be happy to help you via a remote-assistance, but I understand if you do not wish to do that. In that case, I can opt out from your question and open it up for all other experts once again, though I can pretty much assure you that without taking a look in this case, no one else will be able to advise via text either.
Please let me know what you´d like to do.
Thank you very much,
To me is sounds like a background process taking up more and more memory, usually a bug in a program
To test this, do the following
Click Start, type in MSCONFIG and press enter.
Click on the Startup Tab and click Disable All.
Click on the Services Tab and click "Hide All Microsoft Services"
Then click Disable All
Click ok, restart and let me know if it then runs ok please
Go back to MSConfig and enable Norton (it should though still be enable as usually it will enable itself)
Is it still ok?
First try this please
Click Start, All Programs, Accessories, right click on Command Prompt and select Run As Administrator.
A black window will open.
Type in it
press enter and when it has completed, type in
It will give a message "the type of the file system is NTFS cannot lock current drive.
chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts y/n" Say Y, press enter and restart the computer.
Please note, while this normally only takes 10 minutes to run, it can take at times number of hours if windows encounters many issues. If this is occurring it is critical to let this complete as it means you have corruption on the hard drive that it needs to fix. Even if it looks like the scan is not progressing, it is, please just let it run to completion. Windows will then start when it has.
Then tell me how it runs please
