ClamWin: Trojan.swizzor-82 false positive?

hello
I have bitdefender in my computer and I didn't have any problem, I downloaded portableapps with Clamwin I made an scanner which indicate that my computer is completely infected with Trojan.swizzor-82. furthermore my usb device is also infected, particularly firefox portable and audacity.
bitdefender from my computer and online don't detect any virus and neither secuser.com.
I couldn't find any information about the virus and I really don't know what to do, because clamwin does not propose cleaning and the others antivirus I have tried do not detect anything.
I am posting several partial clamwin's reports (I had to stop it because I had to leave, now I am doing another one). please help me!!!.

thanks

I used a file that we are

I used a file that we are likely to have in common:
C:\WINDOWS\system32\LegitCheckControl.dll: Trojan.Swizzor-82 FOUND

Dats/defs Main 47, daily 8162

report clean, as did 8160
at 2:30 CDT [US]

So if it's a false positive I don't know whats going on.

Things have got to get better, they can't get worse, or can they?

was a false positive

I look in clamwin's website, it recommended to scan the files in http://www.virustotal.com. after 35 different antivirus the files detected as infected by clamwin appeared to be clean

thanks

ClamAV Update 8161 Removes Trojan.Swizzor-82

I had the same experience. I found this link while investigating the results:

http://www.gossamer-threads.com/lists/clamav/virusdb/40578

It looks like as of today the signature for Trojan.Swizzor-82 has been removed with ClamAV update 8161.

A second scan after updating to today's latest database for ClamWin resulted in no viruses found, and since I do not allow ClamWin to delete files upon detecting a virus it was definitely a false positive.
