NIS 2014, win xp sp3
Hi and thanks in advance. I run Live Update manually every night and noticed the updater downloading large file sizes every few nights. They are always Virus Definitions @ 150+ MB sizes. I tried removing NIS with the removal tool and reinstalling (have 2013 CD, then update to 2014 through new version check online), but the problem came back after a few days. What I would like to know is:
1) Are the large file sizes and frequency of the Virus Definitions normal?
2) What factors can cause this, if abnormal?
3) How do I fix it?
Thank you for your help.
