From: Takes Ages To Shut Down With Bitdefender Internet Security 2011

It would help if you gave us a little more info on your PC:


- what OS & SP are you running- WinXp (SP3), Vista (SP2), Win7 (32-bit or 64-bit)?


- is it current with all Microsoft critical updates?


- what speed & type processor (CPU)?


- how much memory (RAM)?


- have you recently scanned your PC to make sure there are no virus/malware infections, etc.?


Finally, the most important question...


- do you have any other security programs installed (antivirus, antimalware, firewall, etc.)?


- have you recently uninstalled any other security programs prior to installing BDIS and how did you uninstall them?


Leftover traces of previous security programs which conflict with the real time protection of BD are the most frequent causes of this type of issue.


Awaiting your reply,


You need minimum of 1.5 gig RAM for IS 2011 to work, this came from BD it's self.


Need more RAM to run BD than to run XP or Win 7.


So farewell BD I am going to get more ram.


IS 2010 needs 1.gig.
