Deleting EICAR Files from Opera Browser Cache - How?

Hi,

I'm wondering if someone can help me with a problem related to eliminating files from my internet Browser's cache. I'm using Opera 7.0.

I recently installed a new anti-virus software (BitDefender 7.2). It was suggested that I try to test the effectiveness of my new AV software by downloading a test virus from EICAR.org. The downloaded file is called Eicar Test File and is not actually a virus. I did this and my firewall (ZoneLabs Pro) nailed it.

Here's the problem. There are four files which I cannot delete from my browser's cache. Every time, I launch Opera, a BitDefender warning pops up informing me of the presence of a "virus" despite the four files being safe. The pop-up won't go away until I click OK about 50 times. I have tried to delete these files from my cache to no avail.

The path to these files is:

C:\documents and settings\mike\application data\opera\opera7\profile\cache4

I'd be super-appreciative to anyone who can offer a technique to permanently delete these four files from my machine.

Thanks very much. Best regards.

Mike
