Windows firewall sucks. Get a free one...
Outpost (which I use) or
Onine Armor. Be sure to turn the windows firewall OFF.
Two additional programs (also free) for scanning for malware.
Malwarebytes and
SuperAntiSpyware. Always update them before running scans. Its safe to remove anything found and pre-checked.
I recommend Firefox alternate browser. Its much safer than IE and a lot less problems. Very customizable and easy to use. Built in password manager and download manager. Its also FREE.
About Avira. If you want to get rid of the splash screen (the one that comes up during bootup load) AND the nag screen (the one that wants you to buy the pro version), click
