Top-16 Free Anti-Spyware Programs

In continuation to our previous post about anti-malware tools, we pursue further and deeper into the topic of internet security – for you, our reader. Spyware is especially perilous, as it might steal your passwords, record you, collect browsing habits, etc. Anti-spyware software is usually an antivirus program, general or threat-specific.

We’ve collected 16 spyware protection tools from simple Google search and studied their features, performance, issues. These programs include typical antivirus (Avira, Avast, AVG, McAfee), Internet security suites (eScan, Emsisoft, Comodo, Spybot, Dr.Web, ESET), specific anti-spyware tools (Malwarebytes, Spyware Terminator, SUPERAntispyware, Spyware Fighter, SpyHunter), and one Microsoft tool – Safety Scanner.

There are three chapters of our analysis: feature summary table, brief introductions of each tool with pros and cons, and performance tests. Here goes the first part.

Anti-spyware software

According to Techopedia, anti-spyware is designed to find and remove harmful programs. In turn, spyware is typically installed on a phone/computer in disguise to collect information. With these special anti-spyware programs a user can remove malware that is already hiding on a PC, or use them as antivirus to prevent spyware from installing. We’ve tested top 16 programs (in no particular order) and here’s what we’ve found out.

1. Avira Free Antivirus


Avira is the company known for providing free antivirus and additional tools to users. With components like ransomware / web / mail protection, though only available in Pro version, it comes with Real-time protection. During our tests it detected and stopped 94% of threats, plus there’s a ‘browser safety’ tool that blocks URLs with malware.

  • Fast scan
  • Cloud scan component

It seems the company likes the number 4 – four layers of protection (surf/real-time/behavior blocker/anti-ransomware), four panels in the interface (protection/scan & clean/logs/settings), four types of malware to combat – ransomware, bots, banking trojans, PUPs.

In practice, there’s just one irritating thing: while installing, study every windows carefully, if you don’t want to end up also installing Comodo homepage, Yahoo search, DNS provider, or Comodo Dragon browser. Seriously, guys?!

Performance tests

The third and final part (and probably the most significant one) of review was to conduct spyware detection tests and measure the performance closely. For these purposes we used two standards: the European Institute for Computer Antivirus Research (EICAR) and Anti-Malware Testing Standards Organization (AMTSO). We installed EICAR files and archives, AMTSO files and archives, then ran each of 16 anti-spyware programs to test the detection. Find results below.
