Take the 2-minute tour ×  Yesterday (7.12), i updated my windows
defender as it was an important update and then i thought
everything was alright. I left my laptop into hibernation and
switch it on twice, it was okay, nothing happened.  But today,
after i came back from work, i switch my com back from
hibernation, the security center suddenly warned me that my
antivirus is off, i did not do anything to off the antivirus, i
merely left my com in hibernation mode.  Its my first time
experiencing such situation, i'm worried, please advise. thank
you.  share|improve this question What antivirus are you using?
What version of Windows are you using? What are the specs of the
computer? Please provide more information. –  user3463 Dec 8 '10

Answers 2  My advice is to uninstall your antivirus and learn
how to surf safely. Antivirus programs are resource hogs. I try
not to use hibernation either
