Segmentation fault is here again when I just run avast. ‘avast filename’ works OK. BTW, ‘avast filename’ also segfaults when there are no AVAST environment variables set. I think you should include the following info - “please logout and login again before starting avast” after installation (so that env. vars are set by /etc/profile.d/avast4.sh script). Oh, and you could include avast4.csh script for C shell also.

P.S. I have some files with viruses which avast for linux does not recognise, I could send them if you are interested.
