sorry to be in exact. but for the last few days, the system "sticks" (goes unresponsive), curser doesn't work, "unresponsive" appears on program bar. this is particularly true on internet-dependant programs (outlook, ie, safari, chrome, etc) and Microsoft programs (principally word, less often in excel or powerpoint). startup times are generally much longer than a week ago longer.
it is like something is intervening and then letting go after 5-20 seconds.
security essentials doesn't id any virus or malware or spyware.
