Hi,

DON’t delete them !!
Read here first:
http://www.virusbtn.com/resources/vgrep/vgrep.cgi?terms=mtx-b&product=1
and follow the instructions of Trend, McAfee or Symantec

if you don’t succeed there, try booting into SafeMode (F8-Boot) and REPAIRING the files with avast
wsock32.dll can be restored from avast chest (system files)
& tell us which files remain infected (full path/folder/filenames)

Which Win do you have ?
:wink:

P.S.: here’s a Fix-Tool
