Anti-Spyware Test (Guide)
If any lessons or conclusions can be drawn from these tests at all, they are quite general:
* Spyware and adware can prove quite difficult to remove, even for dedicated anti-spyware scanners.
In the second and third group of tests, for example, one of the installed programs prevented the anti-spyware scanners from running on reboot, a common method used by anti-spyware scanners to remove stubborn spyware and adware that is currently in memory on a PC. As a result, some spyware and adware was not removed by the anti-spyware scanners during reboot that otherwise might have.
* No single anti-spyware scanner removes everything. (1) Even the best-performing anti-spyware scanner in these tests missed fully one quarter of the "critical" files and Registry entries.
* It is better to use two or more anti-spyware scanners in combination, as one will often detect and remove things that others do not.
* Where possible, users should become familiar with the use of HijackThis! in order to remove stubborn spyware and adware that standard anti-spyware scanners fail to remove. Less experienced users should know how to get help from the expert volunteers who provide free HijackThis! log advice and analysis at major anti-spyware forums.
* Prevention is always preferable to scanning and removal, and users should securely configure their PCs and install anti-malware protection to prevent the installation of spyware and adware in the first place.
* Moreover, users should learn to practice safe computing habits, which include avoiding web sites and programs of unknown or dubious provenance and carefully reading End User License Agreements and Privacy Policies.
