Distribution of unwanted software and how to avoid undesirable programs like Malware Crusher

Most methods used for spreading such rogue and questionable software the likes of Malware Crusher “Virus” are optimized for stealth and obscurity so that users are more likely to get tricked and misled into downloading and installing the PUP. One typical method used for PUP distribution are the spam letters – the unwanted app is put inside them in the form of a download link or file attachment and this is how the user gets it. Another method is through sketchy and misleading web ads – those typically get generated by just as sketchy and obscure websites so try to stay away from any web addresses that don’t seem to be reliable. File bundles is yet another very popular and widespread method for distribution of PUPs like Malware Crusher. In this case, the app is bundled with another program and enabled by default under the Quick installation configuration. Therefore, we advise you to abstain from using the Quick installation options when trying to setup a new program on your machine. Instead, make use of the Advanced/Expanded configuration settings and from there uncheck any of the added installs that you think might be unwanted so as to leave them out.

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random

Most such programs have two versions – a free one that people could easily download (sometimes without even wanting it) and a paid one. Now, most users typically only get the free version of the program. However, it really cannot do anything other than scan your PC for issues. Once the scanning process has been completed, the user typically gets notified that there are problems with their machine – errors that need to be resolved, redundant data that needs to be deleted, unwanted or dangerous files that must be removed, etc. However, in order for the program to remove and optimize the PC, the user needs to buy its full version. Now, that would be a fair deal if there are real issues in your computer that need to be taken care of. The thing is that in most cases, the warnings and errors that the optimizer displays are actually fake positives. Most such programs either exaggerate or outright lie to you about your computer having issues that need to be resolved. Of course, if you fall for the bait, you’d be highly likely to actually buy the license for the full version of the program – something that you almost certainly do not need on your computer. This is basically how most such optimization applications function and according to cyber-security specialists Malware Crusher is no exception.

Why is Malware Crusher unwanted

First and foremost, we need to say a couple of words regarding optimization and security software for Mac. More experienced Mac users should know that those machines actually do not really required such software in order to function properly. Apple computers are famous for their innate security and lack of errors/issues that might slow them down or cause malfunction. Of course, this is not to say that getting a viruses or errors on a Mac machine isn’t possible but it is still rather unlikely. However, there are still hundreds of applications out there that are labeled as security programs or system optimizers for Apple computers. The question here is why would you need such a program if your machine is working fine as it is and if there are no actual issues with it. Well, the answer is that you probably do not really need such software. The likelihood of such a program not actually doing anything helpful and not improving the performance of your Mac whatsoever is rather high. The truth is that the majority of system optimizers are a ruse or are at least nowhere as effective and as useful as their developers try to make them out to be. However, lack of functionality isn’t the only problem with applications like Malware Crusher and isn’t the only reason why such software is typically seen as undesirable.
