From Calender Of Updates forum:
Rogue Detections: Old, Not So Old and New Threats
To complete the test we gathered some old (2 years ago), not so old (last year) and new (this year) rogue samples.
Some misleading applications in this test were picked-up by searching the internet using keywords that is similar to non-misleading and popular software. (Example: AntivirProtect is similar to Antivir by AVIRA, SpyBlaster is similar to SpywareBlaster by Javacool). Others were picked by visiting websites that offer database of software (free downloads website). Some were picked by directly going to rogue software vendor’s website.
Note: There are rogue products in these test that were not picked but was offered by existing rogue software e.g. PCTurboPro offers another rogue software: WinAntivirus 2007 Pro.
We selected most of the samples not by risk level but by it’s age level. Please read on to find out why it is IMPORTANT that age level (old, not so old, new threats) is important to be detected especially if the method to get the samples is easy as searching the internet, using a search engine or by going to any website that is offering free downloads.
We’ve run the test by scanning the system with the following free antispyware/antimalware applications:
A-Squared by Emsisoft (A2)
Ad-Aware 2007 by Lavasoft (AAW)
Malwarebytes Anti-Malware by Malwarebytes (MBAM)
RogueRemover by Malwarebytes (RR)
SUPERAntispyware by Superantispyware.com (SAS)
Spyware Doctor Starter Edition by PC Tools (SD)
Spybot Search & Destroy by Safer Networking (SSD)
Windows Defender by Microsoft (WD)
Please note that it is IMPORTANT that a scanner to be able to detect not only the newer threats but also old threats because these threats are still in the wild and are available through different distributions (email, website, ads, phishing etc).
Results1. A-Squared: 91.4% 2. Malwarebytes Anti-Malware: 65.7% 2. RogueRemover: 65.7% 4. Ad-Aware: 61.4% 5. Spybot Search & Destroy: 58.6% 6. SUPERAntispyware: 54.3% 7. Windows Defender: 42.9% 8. Spyware Doctor Starter Edition: 40.0%
Analysis1. It goes without saying, but we’ll say it, anyway, a perfect malware scanner does not exist.
2. Of the scanners tested, a-squared by Emisoft performed significantly better than the others. It only failed to detect six items. This product performed equally well detecting the old, not so old and new threats.
3. Malwarebytes’ Anti-Malware and RogueRemover both performed well on the tests. RogueRemover failed to detect 24 rogue samples and Malwarebytes’ Anti-Malware, concidentally, also failed to detect 24 rogue samples. It should be noted that the failed samples were not the same items on both scanners. When scanned with both of scanners, the total number of samples missed was only ten. This is important to note since it clearly displays the benefit of using multiple scanners. One succeeds where the other fail, but both used together failed on a much smaller group of samples.
4. Ad-aware, Spyware Doctor, Spybot S&D, Windows Defender and SUPERAntispyware all performed very poorly. As this test clearly indicates, there are other scanners available that did a better job detecting threats. If you are currently using any of the scanners in this group, you should consider using the other scanners highlighted in this test either in addition to, or instead of, this group.
Donna, thanks for testing these products!
