DiskFresh malware overview
Software like DiskFresh typically force-opens various sites, e.g., hosting questionable material (e.g., adult-dating, pornography, gambling, etc.), running online scams (e.g., phishing, fake virus/error warnings, etc.), promoting harmful software (e.g., adware, browser hijackers, fake anti-viruses, PUAs, etc.), and even those proliferating malware (e.g., trojans, ransomware, etc.). Hence, by visiting such websites, users can experience a wide variety of serious problems.
Additionally, applications like DiskFresh commonly have data tracking functionalities. Cyber criminals typically target the following information: user/system data, account log-in credentials (e.g., online banking, e-commerce, digital wallets, email, social networking, etc.), personally identifiable details, and so forth.
Furthermore, malware developers often update their programs with improved/additional functionalities. Therefore, the threats posed by DiskFresh may be broad.

The most common functions include: download/installation of additional malware, downloading/extracting content and data, spying (e.g., keylogging, recording audio/video via microphones and cameras, etc.), replacing clipboard data (clippers), encrypting data and/or locking the device screen (ransomware), abusing system resources to mine cryptocurrency (cryptominers), and so on.
However, regardless of how malware operates - its presence on a system endangers device integrity and user safety. Therefore, we strongly advise to eliminate all threats immediately upon detection.
How did DiskFresh install on my computer?
We downloaded DiskFresh from a site offering "cracked" software. However, malware is spread using various techniques. It is usually proliferated by employing phishing and social engineering tactics.
The most popular distribution methods include: drive-by (stealthy and deceptive) downloads, online scams, malicious attachments and links in spam emails and messages, dubious download channels (e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, etc.), illegal program activation ("cracking") tools, and fake updates.
How to avoid installation of malware?
We highly recommend downloading only from official and verified sources. It is just as important to activate and update software with tools provided by legitimate developers, as illegal activation tools ("cracks") and fake updaters can contain malware.
Another recommendation is to exercise caution with incoming mail. The attachments and links present in suspicious/irrelevant emails and messages - must not be opened since that can result in a system infection.
We must emphasize that having a reputable anti-virus installed and kept updated is essential to device/user safety. Security programs must be used to run regular system scans and to remove detected threats and issues. If your computer is already infected with DiskFresh, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this malware.
