What is best antivirus for i3

Well, I use Kaspersky, but I tried Gdata, Bitdefender, Norton...

First 3 are light on the system and update every day, with high detection rates.

I suggest that u run the trial and decide than. In the mean time they will send u @mail for a discounted price, after the trial.

I use the AV only with the free Comodo Firewall , as I like that one, the best.

In addition, I use the Malwarebytes as a scanner. So these 3 are my favorites, there is a lots of them out there to choose from.

And one of the best to clean temp files is CCleaner @ http://www.filehippo.com/download_ccleaner/

CCleaner is a freeware system optimization, privacy and cleaning tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. Additionally it contains a fully featured registry cleaner. But the best part is that it's fast (normally taking less than a second to run) and contains NO Spyware or Adware!
