My Toshiba laptop running WinXP became infected with the ai88 ransomware, which locked up the machine.  I did not pay the ransom.  In the interest of time, I took the machine in to a local shop without shutting the machine down.  This ransomware was most likely imbedded in some pdf files I downloaded from a German site (www.irt.de); the specific files at this site in a subdirectory were V76.pdf and V72.pdf.
 
The proprietor of the local shop indicated this ransomware was particularly nasty and probably originated in Russia or China.  The ransom was to be paid in bitcoin.  Apparently, pdf files are a particular target for imbedding the ransomware.
 
I noticed the machine slowed down, ai88 showed in the tray, and the ransom message appeared on the screen.  I did not believe that ComboFix was a appropriate solution for removal of ransomware so I took the machine in.
 
For the benefit of others, does Superantispyware and/or Malwarebytes detect ransomware imbedded in pdf and other files?  Has anyone in the hack community attempted to trace down the authors or users of this ransomware and attempted to disable their machines and/or internet access?  This assumes that the government(s) in host states where the ransomware is issued are uncooperative.
 
Has anyone on this forum encountered the ai88 ransomware?  In the event the local shop is unable to deal with the ransomware, what fixes are recommended?

Sorry for this long delay.

There is nothing we can do to restore your files.

If you still wish us to remove any remnant items from your computer and registry follow these instructions.

Download the version of this tool for your operating system.
Farbar Recovery Scan Tool (64 bit)
Farbar Recovery Scan Tool (32 bit)
and save it to a folder on your computer's Desktop.
Double-click to run it. When the tool opens click Yes to disclaimer.
Press Scan button.
It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

How is the computer running?
Wait for further instructions.
