Antivirus = Antivira.

Antimalware = Malwarebytes.

Registry/cache cleaner = CCleaner.

I need a firewall that’s JUST a firewall, & hopefuly won’t have any problems with my other security software.

any idea how to download that missing file .dll file? Can I run the Windows system cd, or will that lose files and other items on my computer? No, I dont have a recovery CD. I have run PC Tools registry repair software, I have McAfee anti-virus, malware, security software on my computer.

my computer keeps freezing up & running slow and my default security software says i need virus protection, but it only offers ones with costs. any suggestions?
