Some users may well have experienced a new piece of malware namely Chromium that emulates Google chrome, but generates a whole wealth of Pop-Ups and false Security Alerts resulting in a PC being drowned in unwanted web pages being displayed and audible warnings of a Security attack and a recommendation to phone a bogus support telephone number.
I met this problem last week on a customer's computer, and in order to get the malware removed effectively I used the following method that appears to have eradicated the affected computer:
1. Open Task Manager and look for the Chromium entry(s) and right-click on one entry to locate where it is installed. Delete Chromium from its home location that should automatically displayed.
2. In the run command type REGEDIT in order to access the Windows Registry (Windows Database) and from the Edit Menu type Chromium in the Find box.
3. It may be necessary to run the Find command several times as Chromium appears in a number of different locations within the Registry, and until it is no longer detected by the find Command.
4. Finally, scan the computer with either Malwarebytes Anti-Malware software or Adwcleaner.
5. Hopefully this will remove all aspects of this very annoying piece of malware.
