Possible Virus, otherwise Registry Issue

[JesinFL]

I removed SysProt and ESET. Is there something I installed that replaces SAS and MBAM? I don't mind keeping them around as I've had them for years.

My computer has 1GB installed ram and it's using up to 16% when I checked.
It has 76.6GB on the hard drive and I'm using 37.4GB.

I know it's old and I should upgrade, but this is what I've got for now.

I installed Windows Defender, TFC, and Secunia. Should I delete CCleaner if I installed TFC?

And the Avast situation...why isn't it coming on automatically anymore?

Windows Defender should do just about the same thing but I like to run them on a regular basis.

TFC, and Secunia. Should I delete CCleaner if I installed TFC?

You can get rid of all three, if you wish. You can do the same thing by using "disk cleanup"

And the Avast situation...why isn't it coming on automatically anymore?

If I were you, I would get rid of Avast and install MicroSoft Security Essentials. No need to register it and it updates automatically.
