Now with dozens of varents of ransomware the only good defense is you and your backups. After a decade of PC use I'm sure folk told you to backup what you can't lose.
Without a name of the ransomeware, no one may know which it was.
I've yet to find a ransomware that didn't involve opening some attachment in email or a web page. The zip file was likely the bomb and the post office to date has never sent zip files so that was the source.
If you ever find the name of the ransomware, ask here and on bleepingcomputer.com
Since last few days I have been expecting some packages so I regularly check my email for information. Always I get email when I have packages. Yesterday and today I got many SMS to collect the packages from the post office but they are not mine. Today I traced the package and I knew that it is in our local post office but they are not ready to pick up. After for a while I got an e-mail it looked like from the post office. It had a zip file I thought it won't be a problem. I opened the file then suddenly I got a lot of pop up windows and it said my files were encrypted and it gives some instructions to get into a website. I did not follow the instruction. Immediately I did System Restore. I thought it will be OK, but I was wrong.
I had some files on my desktop now all of them were encrypted I found two files for each folder one is notepad and another is a file to connect to a particular website. My PC has 6 drives including the drive C: . I started to check my eBooks and pdf files all of them were encrypted now. More than 10 years I have been collecting books, but they are useless now. Another drive for gardening VDOs and pictures files were also encrypted. I stopped further checking the files.
I read some advice on the internet so I installed Malwarebytes Anit-Malware it cleaned many files. The OS is Windows 10 Pro. I use only the Windows firewall and windows defender. Before I used Avast only last week uninstalled it.
I am requesting here for help, to get back my files. The OS has no problems still but I do not know what is going to happen in the next hours. Is this ransomeware a time bomb?
What should I do now!
