Spyblaster run problem

I run windows98 on Pentium133. Have had Browser IE6 hijacked to E: Blank and appear to have resolved this with cwshredder but still have problems.Latest cwshredder indicates computer is clean but cannot run spyblaster after apparently successfully installing it several times. Message reads

" this program has been damaged possibly be a bad sector of the hard drive or avirus. Please reinstall it"
Can you please help. Am not computer savvy so need step by step help! Thanks!
