Hi,
I have been using kaspersky for a month (trial version), nothing was wrong
but after some searches in the web I found bitdefender more popular, so I decided to purchase bit defender total security 2013
after installation, I tried to run C Cleaner on my computer but system stopped working, even I couldn't run task manager by pressing Ctrl+ alt+ delete
I was persuaded to reboot laptop by holding power button,
I didn't use C cleaner again, but every time total security tries to perform some sort of action, the system doesn't respond and I should wait until it stops its action
I didn't have this problem with kaspersky ,
what should I do?
thanks for your time.
Operating system :
Windows 7 64bit
