CYBORG9  HEAD'S UP!

A big shortcoming of MacScan is its apparent inability to detect spyware that uses Stealth/Invisability methods which is claimed to render the spyware undetectable. I tested MacScan with one of them (Aobo Keylogger) and MacScan didn't detect it.

Unless SecureMac...MacScan's developer, is able to "sensitize" MacScan to the presence of such spyware, MacScan can't be considered totally reliable.

There's at least one other spyware program out there that claims to be undetectable(Perfect Keylogger).

SecureMac has been alerted to this issue.  
(Version 2.6)

THUS.SPAKE.Z  I just selected three keyloggers from Macscan's detected spyware list, Backtrack, Keybag,

and Keyboard Spy and installed them.

I then ran my copy of macScan v.2.6 updated with the latest definitions version (as of 17th April 2009) 2009007).

Macscan did not detect any of those three Spyware programs.

I suggest that anyone counting on MacScan to detect installed spyware perform their own due diligence otherwise you may be using MacScan under a sense of false security.  
(Version 2.6)

CAESARV  I purchased this antispyware back in 2008. I am still asking myself what it actually does. The fact that it asks your password makes it very suspicious. I decided to use it only for checking tracking cookies, since it is silly to scan all files each time just to find .. nothing.

Big surprise: MacScan always finds the same tracking cookies. I eliminate them, run MacScan again immediately thereafter and, miracle, it detects anew the same cookies that were eliminated one minute before. In the meantime I have found a way to eliminate those tracking cookies for real: go to the browser, check preferences/cookies and delete them yourself. Of course it is quite cumbersome and does not justify the price payed for MacScan. About detecting troyans, my feeling is very negative, suffices to check the list of them in the .plist file. Many programs in the list are no troyans at all. To become a really good proagram, MacScan has a long way to go.  
(Version 2.6.1)

DSW1958  I purchased MacScan through MacPromo and am still wondering why. All it ever finds is a few tracking cookies which I guess is good but I feel that it is not worth the price of admission. Version 2.7 came out and I thought I would see if anything was new or different but have been unable to get the update due to a consistent server error. Another annoying thing about updating is the process of having to go through a checkout process which is totally lame.  
(Version 2.7)

ADONSA  Once you register, you have to put up with Esellerate. :(

And, MacScan phones home (to esellerate), especially when you check for updates. Fortunately, Little Snitch detects the application's attempts to contact Esellerate, and the "phone home" attempts are preventable.   
(Version 2.6.1)

NATE HOULE  Spyware outweighs virus threats for the Mac, and DNSChanger Trojan Horse is a perfect example of that. Its the widest reported threat to the Mac community, and the makers have been distributing new variants. MacScan is a proactive and enterprising utility for Mac OSX security. I've been using MacScan since 4/25/07 and haven't had any issues. The developers are consistently tweaking and improving it. Its obvious the developers at SecureMac take their jobs seriously and I wouldn't have this application on my computer if I didn't _know_ that. SecureMac is super responsive in regards to support/feedback and I believe they're genuinely concerned with betterment of this application. Keep up the good work!  
(Version 2.5.3)

MICG  I've used the MacScan demo and it worked surprisingly well. It found tracking cookies, no trojans or anything else (fortunately).

I just ordered the full version and will write a review of my use of MacScan soon.

I was really impressed by one or more times reading forums and a MacScan Dev or Rep would chime in and give their e-mail and more than kindly offer full support to the poster with some sort of malware on their Mac. I've ordered it because there is a lot of identity theft out there and most of the time cookies need to be enabled. Who doesn't download all sorts of files?  
(Version 2.7)

DGOMBAU  I have been trying it in demo mode, and it is nice and easy. I place a value on my time and don't want to have complex apps that have to be configured in conjunction. MacScan is simple and gets RID of those despicable tracking cookies. If that was all it did, it would be worth the cost for that alone.

Tracking cookies are insidious invasions of privacy. How DARE they! It is like someone with a clipboard and video camera trailing you whenever you go shopping at a mall, and recording everything you look at or pick up, as well as everything you browse in a bookstore.  
(Version 2.5.1)

SECUREMAC  Thank you for your time in commenting on MacScan. MacScan is for your privacy and security, with MacScan you know that you are being protected against spyware for the Macintosh as well as given the ability to scan and remove tracking cookies.

MacScan is a commercial application as well so you can be assured proper support and updates to the program and definition files.  
(Version 2.4.1)

PLASTERPYRUS  Well like its others have said CRASHES, CRASHES, and CRASHES. Makes the whole evaluation thing a waste of time!  
(Version 2.4)
