ADDPC's temp file cleaner is my favorite cleaner, fast, and finds some stuff that ccleaner can miss.

Also theres Revo uninstaller which is a much faster way of uninstalling programs than window's built in add and remove utility.

Commpresion 7-zip winrar
firewall : kerio personal firewall

AV - Microsoft Security Essentials

yo gorman

antivir: kaspersky here


btw, i suggest you mark the freewares in the list

You should add ESET to the antivirus list. You have to pay but it's lightweight and I've never had any problems with it.

All I use is peerblocker and be a little careful, also Ccleaner. Very good computer, no viruses yet.

Shameless clonethread/self link. I thought we were discouraged from making clone threads? Oh well, whatever for rep right?

Cool story, bro.

Check the dates. I don't know which thread was created first but they were created around the same time. Plus I couldn't care less for rep. My thread might be less visible since its a sticky (its a paradox but its true). So chill.

btw I suggest you to add the links. Or else people might end up on scam/fake sites by searching through Google, specially when searching for the less popular software.
