No Linkscanner was installed here. I was talking about the update file size for AVG Antivirus without even Linkscanner installed and the file size for the update was still huge.
Well as I said, the offline installer has some database and hence didn't download a bigger one.
I can give it to friends, they don't have to re-download it
Btw I have 6 tabs open in FF, AVG scan running in the background. Sys performance is fine
