Protection softwares

Previously, I has only Symantec Antivirus, SpywareBlaster and Ad-Aware on my com. Now, after an infection of Coolweb dialer, I boosted the protection with a2 anti-dialer, Spybot and ZoneAlarm firewall (yes, I'm paranoid) but my com has slowed down so much consequently.

Thus, I wanna ask which softwares I should uninstall or what I should do in order to bring my com back into pace. Thanks in advance.

 

Is that a FULL list of the software you have ?

Make sure Windows Firewall is disabled now you are running ZA.

Disable spybots teatimer.

Personally i'd get rid of adaware, and install windows defender, I'd probably also consider not having a2 anti dialer but i've never used it.
