Every time I try to download anything, the program is run and scan, but then I get the following message C:\Users\Norma\AppData\Local\Microsoft\Windows\TemporaryInternetFiles\Content.IE5\PGMJR3MO\WinZipRegistryOptimizer.exe I was trying to download a program to fix my registry at the time. My laptop is an HP Pavilion dv1000 Serial # CNF4451DGQ Product # PM0554UA#ABA and I guess it original had XP & upgraded to Window 7. It has PCI Modem Driver missing or outdated & video card driver also is not working. I don't know if these 2 items are causing the problem.
try using a different web browser until you can get things sorted out. They make redistributable installers for Chrome and firefox so you can DL it on a different computer, but install it to yours.
Then do the general first few things that you should do when you find a problem:
1) full virus scan
2) full malwarebytes scan
3) run CCleaner's cleaner and registry cleaner
4) take an asprin and sleep on it
