What is icon with "$" sign that comes up temporarily during startup

Hold down the Windows Key and Tap the "R" key

In the box that appears type "msconfig.exe" (no Quotes)

The MSConfig Applet will start - on the start-up tab you should see a list of all the programs that start automatically, (actually most not all due to some technical items being started by alternate means), investigate these items, Use google or upload a screenshot of the app here and we'll see what we can advise, and disable those you do not "need" - Think to yourself " do I really want to start "X program" every time to save the 10 seconds it takes to manually open it.

Have a look for anything that may be producing the $ icon especially If we cannot tie this down we can move this thread to our security section and let the pros have a go at solving any possible malware infection

That looks to be about 20% of the complete list, (based on the size of the scroll bar), and I can see multiple anti-malware programs, although you may assume that more is better this does not often if anytime apply with anti-malware, it possible that one AM will scan another's files which is in the process of scanning the first AM's files and by the time that loop ends a long time has passed without any productive outcome.

Take a look at the system security section here and you will see a few ideas of the most efficient way to set-up your anti-malware protection, and I have to say it does not often include McAfee products

With the other items keep just the essentials - Eg Adobe Reader running all the time will use a number of resources and save very little time for anyone who is not using PDF files most of the day, especially these days where most of the internet browsers have built in support for PDF.

Not sure what if anything is actually active on the other pages that are not shown - but what I can see it does look a lot like the start-up overload that is normal with OEM laptop installs - It is "fondly" known in the industry and the enthusiasts as Bloatware and causes a lot of systems to underperform significantly to what they should do

I cannot see anything specific to produce the "$", except you have three entries there for NCP... startup items one of which also included Budget in the title NcpbudgetGui that is one I would not be surprised to be the culprit :)
