Im seening some sticky files in my WIN98 drive, they are exe files. I have written there details below. Can anyone tell me wht the hell are these?

m.exe Size 0 bytes attribute readonly and hidden
x.exe Size 0 bytes attribute readonly and hidden
y.exe Size 0 bytes attribute readonly and hidden
Arcldr.exe size 147 KB attribute readonly, archieve and hidden
Arcsetup.exe size 160 KB same as above
q250204.exe size 0 bytes same as above

They are not virus as my AV is not detecting any such activity. There is nothing fishy running in the background. The only problem is that i dont like these files and what the hell are they doin in my system.
Can anyone tell me?
