PC Pitstop Security Settings FAQ

PC Pitstop uses ActiveX and Javascript to analyze your PC. If you have disabled either of these, you will not be able to even start the tests. You may receive a dialog to the effect of "Your current security settings prohibit running ActiveX controls" or other messages indicating your browser is not running our pages properly. To solve these problems, use the steps below.

If your PC completes at least part of the testing before you encounter a problem, please see the tests FAQ for more help.

What are the correct IE security settings?

IE security settings

To change your security settings in Internet Explorer, select Tools | Internet Option | Security. Make sure you have selected the Internet zone as shown on the picture at the right. Usually, the Medium security level is sufficient for use with PC Pitstop, and you can get to that setting by clicking the Default Level button.

You may encounter a bug in IE where the browser will sometimes show the Medium setting but will not actually use the proper settings for the Medium security level. In that case, click the Custom button and set each individual security setting as shown in the picture at right.

If you are still having trouble after using the Custom settings, double-check that you do not have any security or firewall that might interfere with ActiveX or Javascript. This includes utilities such as ZoneAlarm or Norton Internet Security; see the next item on this page for details.

Do I need to disable my firewall?

PC Pitstop can usually test a PC that has a software firewall enabled, such as ZoneAlarm, Kerio, or Norton Internet Security. If you have changed the firewall from its default settings and made it more restrictive, however, some parts of the PC Pitstop tests may fail. In particular, many firewalls will try to block the Internet upload speed test which uses FTP, and stop the testing process when they do so. You can tell PC Pitstop to skip this test on the debug page or temporarily disable your firewall.

In addition, Norton may flag the upload test as an instance of the Sockets de Trois trojan, this is not correct. Norton may also falsely indicate that our pages are attempting to send personal data to the site. This occurs when you enter personal data into its watch list such as part of your social security number, and these numbers randomly occur in the data we send to our site.

In most cases, PC Pitstop will have no trouble testing through a hardware firewall. The Internet upload test sometimes will not run if your firewall is very restrictive, and it can be skipped through the debug page.

If you are having trouble testing, we recommend that you disable or uninstall any utilities such as ad blockers or popup killers that might interfere with the scripting on the pages.
