Malware researchers cannot confirm if it's possible or not. However, specialists from virusi.hr tell that such threats are usually false. But it does not mean that the virus should be kept on the system for longer period of time.

Avoid opening any spam email attachments
Email box fills up immediately and that is inevitable, but you need to be aware of the dubious content and do not open letters that you have no idea about. Especially when there is an attachment. They might contain cyber threats, such as ransomware, spyware and other malware.
Before opening an email attachment, you need always double-check the information and make sure that you were supposed to get it and it is safe to open. For instance, if you received an information about parcel delivery issues, but you haven't ordered anything, this letter is not for your. Also, if you received an email that asks to print some documents or check invoice information, but you are confused why you were sent this, this letter is not for you too.

How to prevent from getting ransomware
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
