PC was running fine until Micrcosoft Security Essential Update on 10/10/10. Now it freezes up constantly--even in safe mode. I am able to system restore to 9/9/10 from safe mode and seems to run fine. MSE says system at risk and need to do update. Have done this several times, did add .LNK Extensions to be ignored by MSE--seemed to work for a while, now getting system freeze again. What's up? 1 person got this answerI do too
