This usually represents about a week of computer tests.  Our analysis examines all running programs and compares them to our database of known software, using the file name, install directory, and version information to make a positive identification. The scan does not include spyware that consists only of Browser Helper Objects (BHO&#8217;s) or DLLs that may be attached to legitimate programs or run via RunDLL.exe.\n<\/p>\n<p>\nSince the PC Pitstop tests detect unwanted software and recommend its removal, frequent visitors that test their PCs at the PC Pitstop site tend to have less spyware than the normal PC population.  Therefore, our results are most likely to understate the prevalence of spyware and adware.<\/p>\n","protected":false},"excerpt":{"rendered":"<p> PC Pitstop has long been a source of information about unwanted software and how it spreads.
