Ad-Aware 9 uses 35MB of memory because it runs two processes: AAWService.exe and AAWTray.exe, which are the Ad-Aware service and its program notification icon, respectively. When the full scan is running, Ad-Aware uses a whopping 100MB of memory, but it did not slow down the computer while browsing or cause lag for any running programs. A full system scan finished in 9159 seconds, or 2.5 hours, which is impressive considering that it scanned a 320GB local drive and two external drives, 250GB and 160GB, respectively. Smart scan finished in 84 seconds, or 1 minute and 14 seconds, which is another improvement for version 9 of Ad-Aware. Profile scan for Drive C: (320GB system drive only) finished in 3171 seconds, which is down to just 52 minutes and 51 seconds.
For this review, the test system was infected with potentially unwanted software. Ad-Aware was able to detect it all. The only false positive by Ad-Aware occurred when it found Combofix executable. Some other antivirus and anti-Trojan software identifies Combofix as a threat, so it is known false detection.
I had no real trouble updating Ad-Aware 9. There were no more slow or large update processes after the initial updates were installed. This is an improvement, since Ad-Aware v8 would often be rather slow even when updating only the database. I also noticed that Ad-Aware now re-initializes its’ program without issue. In my previous Ad-Aware version 8 review, the program continued to have problems starting Ad-Watch Live and kept prompting me to restart the computer. This is now fixed in Ad-Aware 9.
What impressed me most is that Ad-Aware 9 did not significantly affect the boot-time in Windows. Without Ad-Aware installed, the boot-time of the test system is 23.587 seconds. The boot-time changed to 29.421 seconds after installing Ad-Aware, which means there is only a 5.834 seconds delay in booting Windows. This is better than AVG and Outpost security suites, which have delayed the boot-time of Windows by 16 seconds in my tests.
