My computer won`t let me download anything. I keep getting a message that says ''Your current security settings do not allow this file to be downloaded'' I have checked everything! I have turned all security systems off, set all the possible settings the same as my other working computers, and uninstalled my spywares. But, this message still pops up everytime I try to download anything to try to fix the problem. This must be a virus, worm, etc.? My next step is to do an F10 recover? Any ideas as to why this is happening? Michael...

we really need more information ie what windows, anti-virus, firewall, vpn you are using

Most computer users can readily download files from the
Internet with no issue.


Yet, you may experience an error that will not allow you to
download anything from the Internet. Generally, you can readily resolve this
issue with some simple troubleshooting.

Check your antivirus settings.

More often than not, you simply have too strict of security
settings that prevent you from downloading files.

Otherwise, you can try a few other simple fixes to get your
computer to download files.


If you cannot resolve the issue by troubleshooting, you may
have a serious error that demands the assistance of a computer specialist.



Turn down your security settings.


Go to your browser\'s security settings.

You can change all settings to default or even low settings.



You may even see an option there for enabling downloading.

For example, Internet Explorer has a check box for
"enable file download."


Try to see if these looser security settings will allow you
to download files.



Get a new Web browser.


You may have installed your browser improperly.

You can reinstall your Web browser.


Alternatively, install a new Web browser and see if you can
download files using it.

Sometimes, this will remedy the problem.


Internet Explorer, Firefix, Safari, Chrome and other free
web browsers work well.



Update your computer.


Sometimes, a computer update can remedy your downloading
problem.

If you use Microsoft Windows, install the latest service
pack.


Reboot your computer after the installation to see if you
can now download files.

If you still cannot download anything, you need to see a
computer specialist.

Virus If Explorer Won\'t
Download Anything





The Internet is laced with malicious software just waiting
to take a crack at your personal information.

While rare, certain bits of malware have been known to
hijack a user\'s browser to prevent the download of repair or removal tools.

When this occurs, destroying the infection can be more
frustrating than usual, but is certainly not impossible.

Restart your computer.

You can do this by clicking the "Start" menu,
select "Shut Down" and click "Restart."




Press the "F8" button repeatedly as your computer reboots to activate
the Windows Advanced Options menu.









Select "Safe Mode with Networking."





Press "Enter" to load Windows.

Safe Mode is designed to allow you to troubleshoot issues
with your Windows operating system by limiting the types of processes that can
run -- this should block the virus or trojan from controlling your browser.



Remove the Virus




Download the Microsoft Malicious Software Removal Tool
(MSRT).


MSRT is a free tool developed by Microsoft to assist you in
removing harmful files from your computer.







Open MSRT by double-clicking the icon on your desktop.


Click "Next" to progress to the "Scan
Type" pane.







Choose "Full Scan."


While this scan may take longer, it will ensure that every
corner of your computer is checked for malicious software.







Remove any harmful files that MSRT discovers by allowing the
software to delete them or by manually destroying the files and folders.







Empty your Recycle Bin and restart your computer to boot
Windows in standard mode.


Your browser will now function correctly.
