To remove Ptilselr, you should make sure that there’s no rogue data, software, or processes in the system before you attempt to clean your browsers. Also, to remove Ptilselr, you must clean every browser in your system and not only the main one. Here’s what the removal process of Ptilselr should generally look like: 1. First, you need to start with the programs that are installed on your PC - if there are any recent ones that you don’t seem to recall installing and/or that seem untrustworthy, you should probably uninstall them. 2. Next, you have to make sure that no rogue processes are active in the system - use the Task Manager to single out the ones you think are rogue, look them up, and if your suspicions are confirmed, quit them. 3. Later, you must also restore the default state of the Hosts file, the network DNS settings, the list of Startup items, and also you must clean the Registry. 4. Last but not least, you should go to each browser, uninstall any suspicious/unwanted extensions, and delete the browser’s cookies and cache.
