stupid way for remove infected files detected by avg
Tuesday, October 27, 2009
since avg 8.5 for Linux does not come with removal tool for removing infected files
you have to remove it by hand
first scan directoryavgscan /media/disk
it will come with something like that
/media/disk/watan/watan.exe Virus identified Autoit.BM
/media/disk/show/show.exe Virus identified Autoit.BM
/media/disk/ncyrf.bat Virus identified Worm/AutoRun.EQ
copy and paste output into file say example.txt
now run awk to get first field and get output to test.txtawk '{ print $1 }' example.txt > test.txt
add rm command to beginning of each line by sedsed -i s/^/"rm -rf "/ test.txt
why not loop …;) fear of accidental removal of important files 🙂
it should be looking like
cat test.txt
rm -rf /media/disk/watan/watan.exe
rm -rf /media/disk/show/show.exe
rm -rf /media/disk/ncyrf.bat
nowsh text .txt
hope that might be helpful
