Windows 7 Pro lag without CPU spike

Running windows 7 pro on a roughly one year old Dell laptop Lattitude. No problems, had great response time and the speed was fine. Started experiencing a severe lag on almost everything I do, without cpu spike. Something as simple as opening a folder or searching for a file become a matter of click and wait. Even clicking on the Start buttong can lag. Sometimes no lag, sometimes a lag. I can type a sentence and see nothing appear on the screen, stop typing and see the letters appear. For what it's worth, I am typing this on notepad and not having any lag. I type on MS word and experience the lag. There is no CPU spike and CPU usage could be below 5-10%. I'm able to work, but it is painful. I really need to get this resolved.

* Ran full system scan using Avast and found/removed 2 viruses
* Ran malwarebytes multiple times. Found and removed malware - crossrider; conduit; we-care; facethemes
* Searched HD and registry for files related to the malware; removed them
* Ran full HD scan, including surface scan. No problems
* CPU usage shows no spike in usage.
* Problem occurs in Safe Mode
* Updated the video, sound, keyboard and network drivers

My research in this and other forums has pointed to lots of things, some i've tested. I'm at a loss and could really use some help. Any help would be greatly appreciated.
