Thanks for your replies.

I have the automatic download of new version turned off, so it could have been a glich on the server,  or something of the kind...

As for how I erase my temp files and cache, etc.

I have a program called CyberScrub Privacy Suite  that I always use on the advance settings that cleans that all of that stuff out as well as cookies, NTFS log files and much more while using my PC.

I have it set to overwrite the deleted files 35 times over for a secure delete ( GutzMan Method,) so I pretty much get rid of those files...


What I do is always use that first before using NIS 2011 for a full scan, then I use malwarebytes (on demand,) then on to superantispyware ( on demand again) for complete scans.

But even if I don't run a scan that day, I use the Privacy Suite to clean the files to keep the number of tracking cookies and other garbage at bay by doing a "clean out" once a day.

I hope this helps.
