A new type of ransomware which tries to uninstall security software on victim PCs has been discovered in the wild.

As per an investigation of the malware, AVCrypt will endeavor to not just evacuate existing antivirus items before scrambling a traded off PC yet will likewise erase a choice of Windows administrations.

Scientists Lawrence Abrams and Michael Gillespie say that the ransomware "endeavors to uninstall programming in a way that we have not seen previously," which denotes the malware as unordinary.

The genuine reason for the malware - which has all the earmarks of being ransomware because of its abilities - is additionally being referred to, as a few components seem incomplete. There are components of encryption, yet no evident payoff note, and together with AVCrypt's procedure erasing, it is conceivable the malware may likewise be used as a wiper.

It isn't yet known how AVCrypt targets casualties. In any case, when the malevolent code executes on a casualty's PC, the malware will first endeavor to expel security programming by focusing on Windows Defender and Malwarebytes, or by particularly questioning for different antivirus programming before endeavoring to uninstall the projects.

With a specific end goal to annihilate AV items, the ransomware erases Windows administrations which are required for the defensive administrations to run legitimately, including MBAMProtection, Schedule, TermService, WPDBusEnum, WinDefend, and MBAMWebProtection.

The malware at that point verifies whether any antivirus programming is enrolled with the Windows Security Center and erases these subtle elements through the summon line.

Amid tests, in any case, the scientists say that the malware was not able erase Emisoft antivirus programming through these procedures.

Regardless of whether the cancellation of Windows administrations to hamper AV insurances would work with different arrangements is obscure.

The wiper highlights don't totally decimate Windows constructs, yet likely will cause benefit debasement.

When this stage is finished, AVCrypt at that point transfers an encryption key to a TOR area together with framework data and timezone. The malware at that point filters for documents to encode, renaming them simultaneously.

The payoff note, spared as "+HOW_TO_UNLOCK.txt," does not contain any decoding guidelines or contact data; rather, there is the thing that has all the earmarks of being placeholder "lol n" content.

It gives the idea that the ransomware is being developed stages, and keeping in mind that there is a shaky connection amongst AVCrypt and a current assault on a Japanese college, it isn't known whether the malware was dependable.

Microsoft told the distribution that lone two examples of this malware have been identified thus the organization likewise trusts that AVCrypt isn't yet total.

"This ransomware is very ruinous to a contaminated PC, yet in the meantime appears to transfer the encryption key to a remote server," the analysts say. "Along these lines, it isn't known whether this is a genuine ransomware or a wiper masked as one."
