Does your Chrome browser seem a little “off”, but you can’t figure out why? Maybe it’s eFast.
Here’s another reason to slow down when installing software, especially free software. A new Potentially Unwanted Program (PUP) disguised as the Google Chrome browser is sneaking onto users computers bundled with legitimate software, hidden deep within the ‘Custom’ or ‘Advanced’ settings that most people skip over. Once installed, eFast, as it has been called, serves up ads and tracks your online activities and sells personally identifiable information to advertisers.
“Read the installer screens to make sure what they actually install,” warns Michal Salat, researcher in the Avast Virus Lab. ” The Next->Next->Next->Done approach is exactly why we deal with PUPs daily. If there isn’t an option not to install some additional software, terminate the installer immediately. Better safe then sorry.”
Researchers at Malwarebytes says that eFast actually installs a new browser rather than hijacking your existing one. If you already have Chrome installed, it will replace it making itself the default browser. The fake browser uses the same source code for the user interface as the real thing making it difficult to tell the difference. It is so tricky that it even replaces shortcuts on your desktop that look similar to Google Chrome.
Potentially Unwanted Program – that’s what PUP stands for. You probably already had a chance to meet some PUPs on a Windows PC, but how does a PUP look on an Android phone? How will you know how to handle it? All of this will be explained here.
When a PUP alert attacks you, don’t panic.
For starters, it’s just a warning. It’s not a standard virus and, no, your life is not in danger. PUP detections were made to warn people when a suspicious component or ability is detected within the application.
Let’s say you downloaded an app that’s called “Christmas Carols” (don’t panic about that, either; it’s still a month and a half till Christmas) and a PUP warning hits you. The detection name reads “Android:SpyPhone-E [PUP]”. What should you do? Well, what I would do is to sing Silent Night to that app and wave goodbye while uninstalling it. Why? Well, it’s an app that’s supposed to play Christmas carols and not “SpyMyPhone” or whatever that PUP warning says.
