FAQ
TL;DR: Cost to assess starts at PLN 250, and “The cost starts from PLN 250.” Recovery may be possible but case‑dependent. [Elektroda, KodIT, post #16919423]
Why it matters: If your .xlsx files became .jse after running malware, quick, informed actions can prevent permanent loss. This FAQ is for users asking how to fix .jse-encrypted Excel files and whether pro recovery is worth it.
Quick Facts
- Typical symptom: after running a downloaded .jse, .xlsx files were encrypted and renamed as JScript-encoded scripts. [Elektroda, adsoft, post #16917282]
- Immediate step: stop using the disk; send it for analysis if recovery matters. [Elektroda, KodIT, post #16919222]
- Outcomes vary: sometimes all, some, or none of the data returns. [Elektroda, KodIT, post #16919249]
- Pricing signal: professional work starts from PLN 250. [Elektroda, KodIT, post #16919423]
- Scope needed: labs require the entire disk, not just a few files. [Elektroda, KodIT, post #16921049]
What happened when I ran a .jse and my .xlsx files became .jse?
You executed a JScript-encoded file that altered your Excel files. The result was encryption and renaming of .xlsx to .jse. This indicates a file-encrypting script or malware ran with your user permissions. The original poster reported exactly this behavior after launching a downloaded archive containing a .jse. Treat the system as compromised and avoid further writes to the affected disk. [Elektroda, adsoft, post #16917282]
Can these .xlsx files changed to .jse be recovered?
Recovery is possible in some cases. One expert reports varied outcomes: sometimes everything, sometimes only part, and sometimes nothing. Another member claimed total loss, but that view was challenged without a proper diagnosis. The practical takeaway: success depends on case specifics and prompt handling. “Such verdict ‘Nothing can save!’ without a diagnosis makes no sense.” [Elektroda, KodIT, post #16919397]
Should I keep using the computer after the encryption event?
No. Stop using the disk immediately. Further writes can overwrite recoverable data and reduce the chances of success. A responder advised halting use and submitting the disk for analysis to preserve recovery options. Power down, label the drive, and prepare it for professional evaluation if the data matters. [Elektroda, KodIT, post #16919222]
How much does professional recovery cost for this kind of case?
Expect entry pricing from PLN 250 for professional involvement. That is a starting point, not a final quote. Total cost depends on scope, affected media, and the required effort. Use this figure to gauge whether the value of your data justifies proceeding. Keep in mind that transparent providers will outline next steps after initial review. [Elektroda, KodIT, post #16919423]
Is the initial diagnosis free?
Yes. One specialist clarified that the diagnosis is free and without obligation. This lets you get a professional assessment before committing to paid work. Ask for a written summary of findings and a range for probable outcomes. “The diagnosis is free of charge and without obligation.” [Elektroda, KodIT, post #16919397]
Do labs need sample files or my entire disk?
They need the entire disk. Sending only a handful of encrypted files limits analysis and can block workable recovery paths. The expert explicitly requested the whole drive for assessment, not just the files. Package the disk carefully and include any context about when the event happened. [Elektroda, KodIT, post #16921049]
I only lost around 20 files. Is it still worth sending the disk?
Value is subjective. One user noted about 20 affected files, while experts stressed that only you can decide if recovery is worth it. If those files matter, proceed to diagnosis, which is free, then weigh the starting cost against data value. [Elektroda, adsoft, post #16920849]
What’s the realistic best and worst case here?
Best case: all encrypted items are restored. Middle case: partial recovery. Worst case: nothing is recoverable despite effort. Professionals emphasized that outcomes vary and sometimes nothing succeeds. Plan for all three scenarios before approving paid work. [Elektroda, KodIT, post #16919249]
What’s a .JSE file in this context?
It’s a JScript Encoded script file. In the reported incident, running such a file led to Excel documents being encrypted and renamed as .jse, signaling malicious activity. Treat any unexpected .jse from archives as dangerous. [Elektroda, adsoft, post #16917282]
How do I act fast without making things worse? (3-step first aid)
- Power off the affected PC to stop further writes.
- Remove the drive and label it; do not copy or open files.
- Arrange a no-obligation diagnosis with a recovery provider.
These steps align with expert advice to stop use and send the disk for analysis. [Elektroda, KodIT, post #16919222]
Why do forum experts disagree on recoverability?
They bring different case histories. One expert rejects blanket “nothing can save” claims without diagnosis, noting many encrypted disks where at least some data returned. Variation in methods, timing, and damage explains the debate. Professional assessment replaces speculation. [Elektroda, KodIT, post #16919397]
Will sending just the encrypted files speed things up?
No. Providers asked for the whole disk for proper triage and tooling. Single-file samples rarely reveal the full damage or recovery path. Ship the entire affected drive to maximize the chance of a definitive result. [Elektroda, KodIT, post #16921049]
What’s a simple budget signal I can use before I commit?
Use the stated starting figure: PLN 250 for professional involvement. Ask whether this covers diagnosis only or includes an initial recovery attempt. Request a written scope after the free assessment so you can approve or decline. [Elektroda, KodIT, post #16919423]
How do I contact a specialist from the thread?
The professional who replied said their contact details are in the forum footer. Reach out there and mention your .jse/.xlsx incident. Be ready to provide the whole disk and a timeline of events. [Elektroda, KodIT, post #16921049]
