Having used comodo firewall for some time I thought I would give the antivirus a whirl.
Using XP pro sp2.
The antivirus installed without problem but when I selected “show comodo antivirus” the interface popped up but all status’s read “refreshing” and none of the buttons worked.
The only way to close the interface was to right click on the taskbar and select “close”.
The antivirus itself seemed to be running fine in the background and HIPS was popping merrily and it updated ok.
After hours of research I could not find any information on the problem but during the course I discovered that the about box in internet explorer (which I never use opting for Opera instead) contained no information and the “ok” button did not work.
So searching down this problem I came across the following page: Internet Explorer "About" box is completely blank; Unable to type in text boxes in websites
Running the second item “REGSVR32 JSCRIPT.DLL” from the start/run dialog fixed both my internet explorer and comodo problems.
I only post this to save someone else the potential headache I had. Well that’s not strictly true it was an interesting problem.
Hope it helps someone.
Thanks to Comodo for the hard work in making these applications available for free.
