problem z pobieraniem najnowszej wersji 4.5

[m^2]

It would be fine , at least, give link for download file like tcup45.zip, maybe ESET allow us to download it and secure it out after download. For me I still get message about virus in ftp...

It wouldn't help, antiviruses can extract files from the installers, actually NOD has a problem with some part of TC UP.
If we made a .zip, you'd get the same problem. We could encrypt it, then the download would succeed...but NOD wouldn't allow to extract it anyway.
