To avoid having a filename in one file like file1 match longer names in the other file like file10, file101, etc. and to speed things up a little bit, you might want to try:
Code:
grep -vFxf file1.txt file2.txt

instead of:
Code:
grep -vf file1.txt file2.txt

The -F option tells grep to match fixed strings instead of basic regular expressions and the -x option tells grep to only look for full-line matches.

On some older systems, you might need to use fgrep instead of grep -F:
Code:
fgrep -vxf file1.txt file2.txt
