For some reason after yesterdays 2 updates, whenever i download a file, it will get stucj at 99-100% and result in a broken download. Why is that?

For example i tried to download a file yesterday at 271.66mb it downloaded 271.65mb and dropped connection to filehost. Then i retried with another filehost same thing. Later i tried megaupload since it allows for resuming downloads, same thing happened but at least after reconnection i was able to get that damn 0.1mb.

Allow java and javaw in your firewall and virus software. Disable (or un-install) the port 80/html/web scanner in your virus software.

If this doesn't help, please, provide some example links and a complete and detailed log.
