System Windows 7 Ultimate x64 I have non-stop events in event viewer - security. http://www2.picturepush.com/photo/a/5236020/img/5236020.jpg please help soon

According to this it could be a serious security attack. I would suggest getting a good firewall and running anti-maleware like Malwarebytes to see if there is any malicious code on your computer. Good Luck

I already have scanned using "Malwarebytes' Anti-Malware" nothing reported I already have MSE running without any issues, nothing reported. I have firewall both on ADSL modem/ WIFI and laptop. I have a network PC, somewhere I read make this laptop to Public Network instead of Home Network ... that has reduced the events >>> rite now i only see this : Logon Logogg and Special Logon but i dont see System Integrity / Other System Events.. both these are gone since i put my laptop to Public http://www5.picturepush.com/photo/a/5237168/img/5237168.jpg

Looks pretty normal to me now. Maybe someone (or something) saw a temporary opening and was trying to execute an attack on your system. There are always a lot of logon logoff events when networking. Seems like you solved the problem yourself, I wouldn't worry unless it starts happening again.

But I cant put the laptop to HomeNetwork any more.. maybe just WORK at best or public

It is a puzzler. Have you tried deleting your networks settings and redoing the network from scratch (all computers currently on the network)?

ok both computers on work group now.. and for now i dont see any new events i will try to put both of these to home again... and hope nothing goes wrong. When i put to public i cant share files so i need to be on Work ... although i did not find much issues on work ... maybe home and work are similar just more security on work networking
