VBS/Tqll is a worm written with Visual Basic Script.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest detection database updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note You need administrative rights to change the settings.
Variant:Tqll.A (New Year worm)
This worm is partially encrypted with a simple encryption.
When it is executed, it first creates to the Windows directory a file named "3k.exe". This file is a backdoor detected by FSAV as Psychward.G.
Then the worm executes the backdoor.
Next the script uses Outlook to send itself to every recipient listed in each address book. The message looks as follows:
Subject: New Year ! Body: Wow Happy New Year! Attachment: happynewyear.txt.vbs
The attachment might be named differently.
VBS/Tqll.A uses the BCC area of the mail to send, so the receiver does not see other recipients.
