spacer.gif file is a dangerous file, which is related to SpyMan virus. It's a seriously dangerous keylogger that is mostly used for collecting users' keystrokes and stealing their private information in this way. However, sometimes SpyMan may start taking screenshots for gathering this data. When having it installed on your computer, you may lose your loggins, passwords and similar sensitive information. As soon as it collects a required amount of it, it sends it to its owner.
Once SpyMan enters computer, it creates spacer.gif file. In most of the cases, it is used just to degrade system's performance by displaying commercial advertisements, initiating redirects or performing other annoying actions. However, it may also cause really dangerous activities that may damage your system.
In rare occasions, appearance of spacer.gif does not indicate that computer is infected. That's why you must check the trustworthiness of this file before eliminating it from the system. For that we recommend using RegCure Pro.
