These 5 antivirus suites keep potentially unwanted programs (PUPs) from biting

Eric Geier | Sept. 11, 2014
Adware and potentially unwanted programs (PUPs) might not seem like viruses to some people, but they can wreak havoc and cause major annoyances. It's like comparing terriers to guard dogs: A misbehaved terrier (PUP) may not be as dangerous as a bad-tempered junkyard dog (virus), but the little ankle-biters can sure get on your nerves, and they tend to nip more often.

To enable the elevated riskware detection in Kaspersky Anti-Virus and Kaspersky Internet Security, open the program and click the Settings link on the bottom left of the window.

Select the Additional tab, then click Threats and Exclusions.

Click Detect other software that can be used by criminals to damage your computer or personal data and hit the back arrow.

In Kapersky PURE 3.0, the procedure is very similar, but the placement of the controls and links are different.

First, open up Kapersky PURE and click the Settings link in the upper-right section of the window. Next, click Threats and Exclusions, which is the bottom option under the first Protection tab, and click Objects Detection Settings.

Finally, check Other under the Adware, auto-dialers, other programs options.


Unlike the other vendors, ESET asks you during the initial installation of their products if you'd like to enable or disable what they call potentially unwanted applications (PUA). This enables or disables two of the three PUP-related settings:

The third setting, detection of potentially unsafe applications, detects legitimate commercial software that has the potential to be misused for malicious purposes, such as remote access tools, password-cracking applications, and keyloggers. This setting is turned off by default, even if you enable the PUA protection during the initial install.

Regardless of what you choose during the initial install, you can later access all three of the settings. Open the ESET application and select the Setup tab from the menu on the left.

Next, click Enter advanced setup... Double-click Computer and then select Antivirus and antispyware.

Activate the desired Scanner options and click OK.

Remember, the first and last options were either enabled or disabled during the initial installation. The middle option is considered extra protection that you must manually enable, if desired.


The protection from spyware and other potentially unwanted programs is turned on by McAfee automatically. However, you may want to verify it's still activated. Open the McAfee application and click the Schedule and run scans link.

Click the Real-Time Scanning link, then select Settings.

Scroll down, ensure the Spyware and other potentially unwanted programs checkbox is marked, and click Apply.

Unwanted programs by any name are still unwanted

Remember, antivirus vendors have varying definitions of what they refer to as adware, spyware, and PUPs. One may catch something the other wouldn't. If you still have issues with PUPs after enabling protection provided by your regular antivirus, consider an additional antimalware program that can run along with it. My favorite is MalwareBytes Antimalware.

Though enabling additional protections can help, the best way to combat these threats is educating yourself and other users on the tactics they use to invade your computer. Learn how to spot junk before it installs, and be careful where you browse and what you click and download.
