Hello and thank you so much for your respond 1. No I don't have any of these security software installed on my computer 2. I have AMD Athlon 7750 dual core with 4 GB of ram, and windows 7 64 bit , it's an old pc but it's met the requirements 3. I used the installer that I got from kaspersky website about 4 days ago The pc worked fine the first time that I install and update kscf but the next day after I turned it on it got this wierd freezing And also I don't use this pc for heavy and graphical software just normal daily works like surfing internet and some software like microsoft word
