I did, and I agree.
My issue is that, long after uninstalling them, through Control Panel ----> Programs and Functions, I still find them in Downloads and/or Documents, among others. Which is why I bought CCleaner in the first place.
Anytime I did a full scan with my AV, and rescanned with the two above mentioned, they came out with "0 threats". Whenever I scanned with the apps, before my AV, they would find/fix issues.
IMHO, free versions of any AVs, have limited powers. Hence the need for a third party malware protection.
