Is it Safe to Use Them Together?
If you are using Ad-Aware free for Windows 7, Vista or XP operating systems, rest assured that it's safe to install and run the free edition of SUPERAntiSpyware. The latter will not interfere if Ad-Aware's malware protection detects or tries to remove malware in Window, because SUPERAntiSpyware does not provide on-access protection against malware.
SUPERAntiSpyware's tray icon may appear in your notification area because the default setting is to run a startup scan and also check for detection updates before running. Note that a scheduled scan in the free edition of SUPERAntiSpyware only runs whenever the PC is started, which means you cannot customize the time and date a scan should start. You can configure what type of scan will run, e.g. quick, full or custom scans.
Another reason why there's tray icon for SUPERAntiSpyware is its ability to provide protection to changes in the browser's home page. The end-user will be notified of any changes in the browser's startup page but it will not protect in real-time against malware that might be installed already on the computer, unless the user decides to run a scan using SUPERAntiSpyware. In that case, if the on-access protection by antivirus program such as Microsoft Security Essentials, Ad-Aware Free, AVG, Avast or AntiVir has failed to detect a threat in real-time, it can find and remove it.
Disabling the option to start SUPERAntiSpyware during Windows startup will prevent the startup scan and browser protection features of the program. Remember to regularly scan the computer using the free scanner if you opt to disable its startup item via the program settings.
