Weird TIFF file size after convert from UFO file.

[simpsonss]

hi all,

i'm having a serious problem here. All the while i'm using my Photoimpact 11 to draw my design in UFO file and then convert it to TIFF file for printing.

But recently, when i convert my UFO file to TIFF file. The size of the TIFF file is too large.This happen on my own PC. When i try on my friend's PC it works normal. Afterthat, i tried to zip it up and email it, the receiver's yahoo mail claims that it contains virus.

My UFO file is ~10.0MB.
After convert become 100MB.

For my friend's PC after convert is around 3.4MB.

i tried to scan my pc using NOD32, Malwarebyte and even Kaspersky pure. It shows there is no virus or malware or trojan. I even tried to re-install the photoimpact software.

Can anyone help me on this? thanks.

Why are you 'converting' the UFO. If you have the .UFO open in PI, click on Save As, then save to a format you wish.
TIFF's are large files.
