I have been having an issue for some time now. I am running windows vista on an emachine. I have attempted numerous fixes and have been unable to download any programs for months. Sometimes the error messg will say unknown publisher, corrupt content from reliable source. At some point i was able to get rkill to download as well as, avast and atf cleaner. I scoured thru 25 pages on the forum looking for a cure... to no avail. The latest block was to adobe reader and mp3skull. avast finds no virus. Any ideas? I am open to trying anything at this point. I know its not the router since i was on the phone with belkin for nearly 2 hours. I also tried disabling the firewall and avast with no success. Edit... since windows security wouldnt update, i disabled it and defender months ago. also avast just came back with = invalid file signature. Thanks for any help.
