Trouble installing

HI

I have WIndows 7 Ultimate and have this problem

If I download a .zip file I sem to allways get error saying file currupt, If I download and .exe file sutch as the new iTunes from Apple website I get to the Open File Security Warning then the install just stops (UAC allready on the lowest setting) BUT if I download from a torrent site things work fine!

If I try a direct install from the browser either Chrome, Firefox or IE it tells me the certificates are not supported/reccognised and just stops the install with no other message

I have tried loats of things including

UAC to lowest setting
Install as Administrator
Trouble shoot compatibility etc

Helppppp

Install and update Avast 5, schedule a Boot Time scan and restart to complete it.

In the future, rightclick scan any downloads upon completion.

Can you System Restore to before this problem began? You still need to do the virus scan first.

If not, run sfc /scannow to see if System Files are damaged and reparable..

I am allready running AVG, and have also ran MalwareBytes and Adaware... Had a few tracking cookies thats all... NO virus

SFC has repaired some files but cannot repair others

Also AVG is reporting on some files "The file is signed with a broken digital signature, issued by:" etc etc

You can next try a Repair Install from desktop but with irreparable files you often need a clean reinstall. In your case, I would zero the HD using DISKPART "Clean all" command from Win7 DVD Repair console Command Line, or use free Partition Wizard CD to Wipe Disk.

If you clean reinstall, I suggest ditching the AVG bloatware to install the expert's top new free AV choice, MS Security Essentials.

In the future, rightclick scan any torrent downloads as you have likely been infected and had inadequate protection.
