The issue: every time I reboot the PC after a protected session I get a message that Trend Micro Internet Security has reverted to the previous update because of system instability caused by the latest update (or something like that). Do you have any idea why this may be happening and if I should do something about it or not worry? I expect that any definitions etc that are lost this way are loaded at the next update. The question: On Jan 30 I purchased a licence for Returnil and was wondering if the latest version upgrade is free or if there is a charge for it. I have not gotten around to upgrading (actually forgot about it) but just read in another thread that upgrading is advised.
