About MPlayerX: AppStore or website?

HASP key it’s usb key to authenticate software

if you have software that uses that USB key to run you need to update drivers for that key

do you use some X-Rite devices maybe?

i think you should go where your mac was calibrated and ask to remove old HASP drivers

it’s not ok to have outdated kernel extensions on the system

"Sourceforge" is a rogue site that intentionally distributes malware. Never download anything from that site again. The application that you downloaded tries to install "MacKeeper" and several other kinds of junk, including malicious extensions for Safari and other browsers. If you clicked "Accept" in any of the windows, ask for instructions. Remove any Safari extensions that you don't recognize and need. Do the same in the Chrome and Firefox browsers, if you use either of those. Reset your home page, if it was changed.

MPlayerX is perfectly legitimate software, but like anything else distributed via the Internet (not through Apple's App Store) it has been frequently "hijacked" by sites that bundle malware along with it. To learn how that can occur read How to install adware.

Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.

• Illegally obtained software is almost certain to contain malware.
• "Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements
• If you need to install software that isn't available from the Mac App Store, obtain it only from legitimate sources authorized by the software's developer.

MPlayerX is perfectly OK, and there is no reason to believe there is anything else affecting your system, other than Aladdin's HASP anti-piracy software which appears to be doing nothing other than crashing a lot. It is totally unrelated to MPlayerX.

The download link you provided results in a never-ending repetitious loop of downloading the MPlayerX .dmg file. Opening the resulting .dmg file just starts the download all over again. I have no idea what the heck that is intended to accomplish, but it all points to the fact that "Sourceforge" can no longer be considered a reliable source for Mac software. Forget about obtaining it from there. If you really, really need MPlayerX (and you probably don't) spend the two lousy bucks and get it from the Mac App Store.

MPlayerX is not malicious in itself, so there is no reason to get rid of it. Problems occur when a program has been "hijacked" by any number of software download aggregator sites that bundle malware with an otherwise legitimate installation program. That can occur with anything generally distributed through an Internet download, which is the reason for verifying the source is a reliable one. SourceForge can no longer be considered reliable, nor can most other download aggregator sites; certainly none that accept advertisements for garbage products. Most of them do... advertisements pay the bills.

To over-generalize in the extreme, if you see a "download now" button that is green with white text, run away. Of course I'm being facetious, but malware peddlers appear to be fond of that color scheme. I surmise it's effective.
