A hacker installed .ini files on my computer, which i
believe are for his hacking usage. they are located in
c:winnt\system32\web, is that a normal folder in windows?
If not , I want to delete all the files in there, they are:
1. aliases.ini
2. bnc.dll
3. f*ckflood.txt
4. ie6.dat
5. kernel33.exe
6. moo.dll
7. psexec.exe
8. remote.ini
9. wi354.dat
10. win32.dat

is it ok if i delete all the contents in this folder? or
how about if i delete the whole folder? i really would
like to get rid of this hacker.
