Ad-Aware and SUPERAntiSpyware will run in Windows 7 and earlier edition of Windows. The file size of SUPERAntiSpyware’s installer is very much smaller than Ad-Aware Anti-Malware: 7.03MB vs. 73.5MB. There is no third-party add-on in the installer of SAS while Ad-Aware have bundled their anti-malware with Google Chrome which is optional during installation.
A reboot is required when installing Ad-Aware while SUPERAntiSpyware do not require such. It’s quite impressive to see anti-malware vendors to improve their program’s installer because I’m finding many of them requires no reboot to start protecting or scanning a computer (e.g. AntiVir, Avast!, A-squared, Malwarebytes Anti-Malware, Microsoft Security Essentials and NOD32 to name a few).
Ad-Aware will use a lot of hard-disk space than SUPERAntiSpyware: SUPERAntiSpyware will only use 27.9MB of space while Ad-Aware application will take 107MB and 568KB for its Download Guard for IE browser.
There is existing issue with Ad-Aware’s installation of its Ad-Watch Live: The notification balloon keep prompting to restart the PC. The possible fix is to follow the advice in their forum but after doing all the suggestion, Ad-Watch Live will continue to not install turn on. The only work-around I have found is to uninstall existing anti-virus and firewall before re-installing Ad-Aware.
