About this threat

How does this threat spread?

Malware specialists aren’t completely sure how this infection reaches computers but it’s likely that it could use the freeware bundling method or program cracks. In the case of the former, you need to make sure that free software has nothing attached to it before you install it. If there is something, which you can check in Advanced or Custom settings, make sure you uncheck the boxes of every single extra offer. Software cracks are also a great way for Trojans and other kinds of infections to spread. This and the fact that you are basically stealing a program is why you should not look for cracks.
