Windows 7: LOW Computer Memory- ONLY 90MB or less Free Memory? Soo Slow?

Hello, i have a Windows 7 64bit OS and i am running a Laptop.
Ever since i had this virus (Win32 malware gen) which kept coming up with a notifications of the virus on avast every 2-5 minutes my computer was running slow and when i deleted the virus, by dragging it in to the recycle bin and erasing it, my computer was still running slow?

(MY COMPUTER ALWAYS HAS UNDER 100MB FREE MEMORY WHEN I RUN 1 GAME OR APPLICATION)

MY LAPTOP SPECS;
System manufacturer- EMachines
System Model- eME443
RAM- 2 GB DDR3 memory
Processor- AMD Dual-Core Processor E-350
Graphics card- AMD Radeon HD 6310



I've tried so many things to fix this problem, I have tried;
-Deleting the cache of all my browsers
-Cleaning and defragging my registry with "Clean My PC- Registry Cleaner"
-Deleting the 'appdata' cache
-Installing new drivers
-Searching for viruses with avast
-Doing a Memory/RAM test with "MemTest"

(By the way I currently haven't been getting virus notifications, so i don't think the problem is a virus)

(one time i got a BSOD, which on the top of the BSOD it said something about 'PAGEING ERROR)


I attached Images of;
-My Task Managers 'Processes' tab
-My Task Managers 'Processes- All users' tab
-My Task Managers 'performance' tab
-My Avast virus report of the virus I had before




SO COULD ANY ONE HELP PLEASE WITH THIS LAG PROBLEM

Hello GiCOMMANDO and welcome to Seven Forums.

I would run another full scan using the free Malwarebytes. It has a good reputation of finding things other products miss. Another highly recommended free on-demand scanner is ESET Online Scanner. (No anti-malware product is 100% effective 100% of the time. If there was such a thing we'd all be using it. A second - or third - malware scan is a good thing.)

ESET

Malwarebytes

From your first screen shot it appears that a portion of your 2GB RAM is being set aside, most likely for your graphics card. Your computer is starting out with less than a full 2GB RAM and 2GB is the absolute recommended minimum. I'd give serious thought to increasing RAM to 4GB (I believe your machine will handle up to 8GB and prices are very low right now.)

Because of that virus, it's possible that critical system files may have been damaged or corrupted. Try running a system file checker scan from an elevated command prompt (option two, this tutorial.) If problems are found run the scan 3 times rebooting in between each scan.

SFC /SCANNOW Command - System File Checker

And don't forget your basic maintenance chores such as disk cleanup, defrag, disk check, etc. Please post back if anything helped or not.

I forgot to tell you i did a defrag, and do a disk check but no errors were found?
Yeah it probably is a problem with my window critical system files...
When i did the 'SFC /SCANNOW' command it didn't work, it went to 41% then it stayed like that for 5-10 minutes, and it said " Windows Resource Protection could not perform the requested operation."

But when i did 'SFC /VERIFYONLY' command it worked and i got the sfcdetails.txt in the attachments.

Could you please review the attachment and tell me how i fix the windows files?
Thanks

I think I'd forgo any other troubleshooting steps and do a repair install. This procedure should preserve your user accounts, data, programs, system drivers, etc and can probably be done in just a couple of hours.

Repair Install

Or in the alternative, you might consider a clean reinstall. One of the Forum experts prepared this tutorial.
