System Freeze
Win7 Home Premium, 32bit, Sony laptop, 3GB mem, 250GB HDD
Need opinions on why computer froze and action to take:
-Downloaded Google Chrome Beta 15 with adblock and clicknclean addons.
-After about 3 hrs, computer suddenly seemed to freeze. Could not connect to any website using Chrome or IE9. Internet connection troubleshooter showed no problems
- Chrome and IE 9 just displayed a blank page with no notice that "IE has stopped working" just a blank page with the little circle showing the page was trying to load.
-Kaspersky Internet Security would not launch and also froze.
-I use a VPN but same problem existed using both VPN and normal connection. I was using VPN when system initially froze.
- I did a restart, uninstalled Chrome, ran a scan with Kaspersky and Malawarebytes with neg result. After restart, computer "seems" to be normal.
Should I be concerned a virus/malaware has invaded my system ? What may have caused this unusual freeze without any system notification ? Should I take any further action ?
Thanks for your help.
