try this ;)
# awk 'NR==FNR{sub(/./,"",$1);if($1>2&&$1~/^[0-9]/)a[$0]=$1;next}{b[$0]++}
END{c=0;for(i in a){for(j in b){if(j~a[i])c++};;if(c==0){print i}c=0}
}' file1 file2

awk 'NR==FNR{a[$0];next}$1>3{for (k in a){if (k ~ $2)next}print}' fileB fileA

Guru.

You can redirect the output to a third file for example fileC:

awk 'NR==FNR{a[$0]++;next}a[$2] && $1>=3' fileB fileA >fileC
awk 'NR==FNR{a[$0];next}($2 in a)&& $1>=3' fileB fileA >fileC

If...

This also works
grep -f fileB fileA | awk ' $1 >= 3' > fileC

awk 'NR==FNR{a[$0]++;next}a[$2] && $1>=3' fileB fileA
