This is very common error since the release of Windows 7 and Internet Explorer 8; we thought we had a major virus but this turned out not to be the case. There are some security settings that need to be tweaked inside the Internet Options to allow downloads again.
“your internet security settings prevented one or more files from being opened”
Problems Opening Files on LAN

You may get the “these files cannot be opened” error when opening files on a network drive.
Control Panel –> Internet Options –> Security Tab

I unchecked them all and it works! The “your internet security settings prevented one or more files from being opened” didn’t block me and I can now open files on network drives.

Problems opening files in Internet Explorer, Firefox & Windows Explorer

Setting these for both the Internet and Intranet settings should take care of the file open problems. The setting I discovered during my troubleshooting is “Launching applications and unsafe files”. This can be set in two places depending on your network setup.
Change the settings in Internet Options
This is an error from Internet Explorer security settings found under your “Tools” –> “Internet Options” –> “Security” tab –> “Local intranet” or “Internet”.


Make sure you can download files
You may also need to enable File download to get past the “these files can’t be opened” inside the Internet Properties.

Change this is Group Policy
If you operate in a domain you will need to add the settings to a new GPO to remove the “your internet security settings prevented one or more files from being opened” error from all network systems at once. This method worked for me.

Open your Group Policy Management Editor and either create a new IE8 Policy or use an existing one and go to User Configuration –> Policies –> Administrative Templates –> Windows Components –> Internet Explorer –> Internet Control Panel –> Security Page –> Internet Zone –> Launching programs and unsafe files
You should do this for both Internet zone and Intranet zone.

I am experiencing these problems all of a sudden too!!! (My system worked fine yesterday, today I can't play The Sims 3 and can't install antivirus software. I followed the above instructions, but it is still happening. I have run virus/spyware checks and they are clean.
I don't know what to do - there is obviously something wrong.

I've found that once you install your own AV you'll have major slow downs, downloading issues etc. if you don't turn off Defender. It's always good to start it up to update the definitions every now and then though, before re-stopping it.

Hello Guys,

same problem:
Can't open files that are saved on my HDD especially install-packs... Played around a little bit: Defender is off now(again), plus I am actually not too bad with tweaking security settings. But still NO CHANCE!

Does anyone think that it could be related to a certain virus? I had one detected and removed 2 days ago and I think of it as a bit of a weird coincidence that it also effected my AV (automatic start up is now blocked) which i'm now not able to re-install any more.

Thanks!

SOLVED! Here's my way... well, not really:

This Forum hel;ped me out already not long ago. It was about issues occuring after having updated /activeX elements

I quote:

I tried for scanning the system, it showed no spywares, no malwares, even the sfc scan showed no errors. Would you tell me how did u fixed the Activex problem. I don't know a solution for this. help..????
You should delete 1 extra (parasite) zone from HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\
with pseudo-graphic number, you'll see it before zone number 0 (The pseudo-graphic number they speak of before zone number 0 looks like a miniature upper case "L".) .
It seems this is a bug of Adobe flash player update

Credits for solution go to Snoggins, whom it was given from Microsoft.
----------------------------------------------------------------------------------------------------------------------------------

After all those Problems I now had another look: Now the "L" mentioned above, now appeared to be an UPRIGHT RECTANGLE.
I showed it who's the boss (DELETED it).

DONE. SOLVED! New AV installed! No more prompts - without "lowering" Internet security settings. Everything working fine again! The sun is shining - damn, I hate computers sometimes...

I HOPE IT MAY BE HELPFUL TO THOSE THAT FAILED WITH OTHER SOLUTIONS!

Thanks BrettM,

Very helpful - Worked for Server 2008 as well. This was a lifesaver. Would not let me access a command prompt or anything until I performed these procedures. Also discovered in my searches to open a command prompt on a 64-bit O.S. you can type this in the Search/Run box - %windir%\SysWoW64\cmd.exe
