Logitech Quickcam files

Windows XP Home SP3. Fully patched.
I updated to Avast 5 last week from version 4.8, and performed a quick scan afterwards which showed clean. Also have run quick on demand scans during week from SuperAntispyware and Malwarebytes which showed clean.
Today I ran a full scan and it came up with two infections which were removed to the virus chest.
Both these files appear to pertain to the long time installed Logitech Quickcam software which has never been flagged before today, so wondering if they are false positives.
The files are
C:\Prog\ VidCtrl2.exe HvideoS2.exe Threat Win32 Gen
C:\Windows\Twain_32\HvideoS2.exe Threat Win32 Gen

Not sure how to uplift files to Avast Lab so if anyone can walk me though it if needed, I would appreciate all the help I can get. thanks

Hello,
send the files to virus@avast.com with “False positive” in subject.

Thank you,
Milos

Thanks for reply but I have submitted them through the Avast program from the chest. Do not know how to send possible infected files via email.
Please advise if this is not correct procedure. Thanks
