After installing Firefox then closing it, I cannot open it, PC says it has been cancelled due to restrictions on my computer
I have run Firefox for over a year now. However I ended up with various pop-ups recently though they were easy enough to remove and didn't effect Firefox in any obvious way. In the past few days every time I have attempted to open Firefox, even right-clicking on the .exe file a warning pops-up saying "the operation has been cancelled due to restrictions in effect on this computer. please contact your system administrator".
I uninstalled and reinstalled Firefox and it worked fine, only to return to that warning message after I closed and re-opened it. This has also effected Google Chrome in the exact same way even though I never owned Chrome until all this business began. Internet Explorer, which I'm on now has suffered no problems.

Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.
