You may see regular containments on your browser, almost always nothing to worry about, usually a benefit by suppressing information requests, but some useful notes below.

Depending on the sites you visit, if you have the UI open, you may see repeated relax and contain cycles as a page refreshes. This depends on several things. It can be spyware and the containment will often be all that’s needed. It could be an actual malware infection from the website. But a combination of adware, spyware, and many requests for information from a site may raise smoke signals. A smoke signal is an early warning that starts containment and further analysis by Cerberus.

In almost all cases for trusted sites, the containment will be relaxed quickly as it will likely be found to be legitimate. But you may see this happen repeatedly on particular sites with high volumes of request for information from your computer. For sites that cannot be trusted, this may be a sign of a real problem. But Cerberus will take care of that.

This action on your browser process is necessary as it is possible that malware is planted on a site or that your personal information is being distributed widely. As a plus, the containment and relax activity has the positive effect of reducing these requests when a legitimate site realizes they are not being fulfilled with the data it seeks. If you have the UI open, there is no need to pay attention to those browser occurrences. It is rarely something that Cerberus cannot simply handle quietly and be done with it. Cerberus will tell you with a small, non-intrusive message balloon in the lower right corner if there is anything of significance happening with your browser.

In rare circumstances, after extensive testing, we have seen that a browser process may be quarantined. When this happens, you will not be able to refresh or create new connections. The proper action if this occurs follows. First, if you are sure you are on a trusted site, you may open the Cerberus UI, click on Customize, highlight the quarantined process, and click “Remove Exception” to clear the quarantined item. If there is a problem with the site, it will be quarantined again. You may want to stay off the site for a few days while they find and deal with the problem. Secondly, if you clicked a link unknown to you or are not on a trusted site, you will want again to release the quarantine but no longer visit that site or, better, block it in your browser.

Cerberus did its job in quarantining but it can only quarantine your browser. In order to resume browsing, you must release the browser process from quarantine. The browser is the process through which the monitored communications are being attempted. The website itself is not the process trying to communicate. It is only sending out the request to the browser. Also, put that site in the category of unsafe browsing.

By the way, the browser containments were almost wholly in the lab where the limits were pushed. In beta testing by actual users, there was only one occurrence. In that case, a later return to the site did not quarantine the browser again.
