Editors' Review


Advanced System Optimizer 3 gives people a comprehensive suite of utilities fronted by an interface that showcases an excellent use of color-coded icons, making banal system tasks easy to complete--if not exciting. However, its restrictive trial could prevent some people from fully exploring the program.

The program attempts to be all things to all people, and includes tools that can be split into three categories: maintenance, security, and backup. Advanced System Optimizer focuses on the maintenance side of things, and includes a Registry optimizer and cleaner, a disk defragmenter, a disk repair utility that claims to fix errors before drive failure, an explorer for managing disk usage by file type and size, a memory optimizer for freeing RAM, a game mode, and a driver updater. Security is not the focus here, but it does include malware protection, secure deletion, and a file encryption utility. Backup and recovery features include rescuing deleted files, a backup manager that streamlines restoration, and a separate system file backup and restore feature. The Smart PC Care feature is new, and allows users to run multiple maintenance tasks with one click.

The new main window is well-crafted and takes a page from security suites by providing status updates in one place, letting you know what the problems are in general terms. At the end of a scan, a small Details link will appear to the right of the scan type. Click it to drill down to see specifically which files, Registry entries, or cookies will be deleted. The harsh trial compares favorably with its competitors, but, like them, it's so tight that most users will find it challenging to fairly evaluate the program's efficacy.

Editors' note, November 6, 2009: The review has been updated to fix an inaccuracy, but the overall score has not changed.

"Simple to use and reliable !"

 |  Version: Advanced System Optimizer 3.6.1000.15950


Advanced System Optimizer is a superb program. I have been using it for the last 5 years and I am happy that I had given it a try. I find it much better than all other optimization tools I had used before.
Its Smart PC Care feature is really very helpful, does almost everything in single click.


No cons so far.

"Do a Search for Spigot Before Installing"

September 25, 2014  |  By jycnan

 |  Version: Advanced System Optimizer 3.6.1000.15950


Seriously, I love the program, even have the pro version. It does everything, however


I installed it. MalewareBytes and Avast kept screaming at me about Spigot. Chrome started crashing and my country music station is in Chrome and crashing 10+ times a day is not an option!

So I Google Spigot, it's malware. Always looking to the last thing I installed when things are not functioning normally, it was ASC. I Googled that and Spigot together, boy was that an eye opener!

Why in the 'heck' would a malware protector bundle it's software with malware? I'm having a REAL HARD time with this one.

I emailed ASC about their use of Spigot since I also had IOBytes with it. They openly admitted it. I asked them if I removed ASC and IOBit, could get rid of it. They said no! They said, I shouldn't have installed the 'toolbar'. I said I didn't, I don't install toolbars. I like my computer set up just the way it is.


I took me 30-60 days to finally eradicate Spigot from my system. ASC will never be installed on another machine. I thank my brother for suggesting Malwarebytes. Once installed, IObits became useless.

"Great utility for a well put together PC."

I've purchased and used at least 20 different maintenance programs in the last 35 years that I have been using PC's to make my living on. Some are okay, some are ridiculously poor, even harmful, and some are very useful. I have to rate ASO as excellent compared to all of the other maintenance programs that I have used. I have studied all of the reviews that I have found on ASO and I think that anyone that gives this utility a poor rating should look into buying a new and different brand of computer.


The first time I used the driver utility was a poor experience. Lately though it seems to be considerably more accurate. Although I wouldn't recommend it for the novice user. And the advanced user needs to use caution. Also if it had an optimizer for SSD drives, if thats possible, it would be a more complete package.


A very good reasonably priced utility for keeping PC's uncluttered and running smoothly.
