Is there a way to determine if a system runs faster after malware removal?

I am frequently called on, mostly by friends and family, to help cleanup computers that have malware on them. I have been googling, but not able to find any sort of program that can help me verify the difference in system performance before and after a computer has been cleaned.
I am not looking for the standard benchmark test, that puts stress on the components, but rather something that simply shows a score of how fast the system runs. Obviously this would have to be a lightweight application to be able to run on a potentially highly infected machine before cleanup.

Any ideas?

Thanks,

I don't believe such a program exists. Sorry.

If you are supporting Vista, Windows 7 or Windows 8.

Viruses, spyware and other malware can slow your boot to a crawl ...

You could create a batch file containing this one liner to determine if the startup process gets faster. It will collect data from 20 startups and keep overwriting the output each time it is run, adding the newest boot time to the first entry.

wevtutil qe Microsoft-Windows-Diagnostics-Performance/Operational /rd:true /f:text /c:20 /q:"*[System[(EventID = 100)]]" /e:Events > "%userprofile%\Desktop"\AVerageBootDuration.txt

note: you will need elevated privelages to run these batch files.

You would already have these events available on Windows 7 and 8.

Try checking them first before following above steps.

Open event  viewer, go to Microsoft -> Windows -> Diagnostics-Performance and check that you should have Boot Performance Monitoring (Event ID 100)  and Shutdown Performance Monitoring (Event ID 200).
