[Inactive] It's time to get serious!

My girlfriend and I have been the targets of a hacker for 4 years! We've had our email accounts hijacked at least a dozen times. Letters and files have been deleted. Just last night someone went into my Yahoo email and sent a link to 3 of my contacts at 2:30AM. This is it: http://motyle.hiena.eu/images/auua.php

We've tried everything from changing our passwords every day, to installing and running various Antivirus software, to clean installs of Windows. But in time this hacker eventually reappears. Nothing we have done under the advice from people here has been able to stop this person.

I am at the point where I am seriously considering hiring my own legal hacker to find out who is doing this and file charges of harassment against him or her.

My questions are:

1) Does anyone here know of a good Internet Security Company that can find this hacker for me?

2) Does anyone here know of companies that can provide constant protection for my computer?

Thank you.

If this has been happening on the same computer It's just as likely that it's some sort of worm that's stealing passwords. Before you do anything else I'd run the scans in the sticky at the top of this forum..

and let our experts have a good look.

Realistically an actual human would be wasting a huge am't of time and effort to hack your email acc't just to send out spam for online pharmacies. This is almost always done by malware... although it is possible there may be a human receiving the info at the other end and doing the deleting etc.

As for your other questions I don't personally know any services to recommend but I do know that it would be hugely expensive and time consuming with no guarantee of success.

FWIW, passwords should be at least 12 characters with upper and lower case and some numbers... even better if there are other characters like !@# etc.
