YES! Free version, regular use, and keep it updated. I love how it digs out my kernel rootkits, ADS, etc. Let's me know it digs deep. Reliable scanner program that doesn't conflict with other solutions.
That really depends on the end-users particular configuration and system IMO. For example some like myself have tried in vain to adapt MBAM for the longest time without success, only issues which are directly related to swissarmy driver and it's incompatibility with other security solutions. Others may be better compatible and with such reason to favor the app that works best for your setup. HitmanPro has a very unique approach that's a real crowd pleaser without a doubt, however you'll find some users experience issues, and as with all Anti-Spyware Scanners/Cleaners, there are the always present False Positives.
Ccleaner takes care of cookies. Having a password manager gives me very little reason to save any cookies. I must admit though that I did install SAS on a machine yesterday and it took care of the issue.
I decided to give SAS Pro another shot. I figured I paid for the licenses, I should use it. What the heck, it gives me another layer of security. Hopefully they will be doing updates on the weekends & Holidays soon.
