I would greately appreciate help with a problem: I have been unable to download files from any site on the internet for several days. When I try to do so, I usually receive only part of a file, after waiting several minutes. I often receive an error message: "NSIS Error. The installer you are trying to use is corrupted or incomplete. This could be the result of a damaged disk, a failed download or a virus." I have researched this over the internet, unstalled software that I installed before the problem started, tested and cleaned/defragmented the hard drive, and re-installed the latest Windows Installer from Microsoft. However, the problem continues. Note: I am running NOD32 Anti-virus, Online Armor in real-time, and Malwarebytes Anti-Malware in real time.) Besides the download problem, my system is running very, very slow. (I installed Online Armor and Firefox about 2 weeks ago and recently uninstalled those to see if it made a difference - but no joy). All that it is left it seems, is the strong possiblity that I have picked up a virus somehow. Please help!
