I have presently Comodo Firewall Spybot Adaware SE personal and cc cleaner!
Should I get rid of one?
In a word no.
Comodo is important for the security of your system and will help to stop your computer from being hacked into.
Spybot is a very good antispyware app, as is Ad-Aware personeal SE. You can run scans with those programmes as and when you want.
Ccleaner is an excellent application for getting rid of junk files from your system. Again, you can run it whenever you want.
Thanks so a I will keep everything!
