wscript.exe - Shortcut virus

[AnthonyAT33]

Pretty much the same as in this thread:

http://forum.avast.com/index.php?topic=142075.0

My brother was careless and plugged in the USB flash drive that was previously used at a university computer which was infected with the "shortcut" virus as well as autorun.inf (Which I believe have sorted/solved).

we need logs from Malwarebytes / OTL / aswMBR.    http://forum.avast.com/index.php?topic=53253.0


then follow instructions from argus

Please download Farbar Recovery Scan Tool () by Farbar and save it to your desktop.

Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.

• Double-click to run it. When the tool opens click Yes to disclaimer.
  
• Under Optional Scan ensure "Driver MD5" are ticked.
  
• Press Scan button.
  
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  
• The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

Remove AutorunRemover not necessary.

[AnthonyAT33]

Note: I had to disable Avast! in order to run the FRST fix.

How do I clean up my USB flash without it infecting my PC again? Will MC2Shield do the trick?

Thank you for the help so far.

Here's both logs.

I had it run three times because I never got the log file to pop up indicating that it finished the first two times, so here's three logs.

Order of logs goes as:
1. zoek-results2013-12-17-131748
2. zoek-results2013-12-17-154901
3. zoek-results
