Once booted, windows takes 10 minutes to connect to internet after installing 360 ver. 5.1.0.29

Running vista pro, each time I restart the PC windows boots okay, but cannot connect to the internet for abouut 10 minutes, during this period , if I try to  start internet explorer or outlook they freeze and hang for ages, after the 10 minutes everything works fine, allbeit a bit slow.

 

Help Please ???

 

Thanks
