I am unable to dowload anything on my PC, I cannot even upgrade Microsoft Security Essentials. Basically, I initiate a download, but it will download 99% of something and then just stop...regardless of what the download is. I run security scans with Microsoft Security, but it never picks up anything. This is driving me crazy!!! Help!
By stop, U mean any error messages or just dissapears?
try another browser
try cleaning your temp, ie history, bla,bla,bla... (U can use CCleaner)
resett IE to default settings
Tools>Internet Options> Advanced tab
Close and reopen IE. Try downloading something.
try downloading with IE clean, without any addons (U can consider this as a safemode for IE)
Start >run > and type
iexplore -extoff and press Enter
Try and download something
