AdwCleaner requires a restart to finish up, as I understand it. If you know differently, I'm genuinely interested.
>ComboxFix is unnecessary.
Respectfully, I disagree. It's caught things that the others have missed. Anecdotal evidence, sure, but in my experience it's proven useful.
Most of the time new laptops are not for speed purposes - there is a misconception that a new laptop is a fresh start, not necessarily a much faster computer.
The thought process invariably is: this laptop is slow and full of ads, I need a new laptop to start over without the ads and _new is best_. My clients are mostly non-technical, that's why they call me; technical clients (say, 1 in 10) are more willing to explore SSD and appropriate RAM.
TV-advertised laptops for 200-250GBP are very appealing for my client demographic. It irks me, sure, but then sometimes people have to learn by doing. The tide is very slowly turning.
