Can anybody advise??

Every exe or zip I download from P2P and internet is corrupted.
Every one.
All of them !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I have no idea why.

I use Win XP Service Pack 1
I was having this problem before I added SP1 too.

PC is five years old, but wasn't having this problem til I installed XP a couple months ago. Seems XP related anyway.

Nothing at Microsoft on this. Don't know who else to ask.

Really driving me crazy. Using latest McAfee and virus dat files. Have done MBR scan in DOS. Nothing there.

Even the smallest downloads of a couple megs are doing it. Every time.

I'm going crazy.
Oh, I get most downloads at Kazaa, but have had this prob with internet files too.

Please help.
Thanks.
