Hi most files in my laptop D-partition were encrypted with a .browec extension     Apparently, it's some type of ransomware, because I'm asked to send money.

Those files are no longer readable despite renaming them.  I'm not an IT guy, what steps should I try to decrypt these files?  Is a decryptor already available for this? 

What I've done is using an antivirus program to have all viruses removed.  But this certainly does not help with decrypting.

Thank you in advance.
