I must make a summary comment here:
"Everyone should be using AVG Free Edition only"
Reasons:
1. 99% of all 3rd party "security packages". being Norton, McAffee, Trend, Panda etc all come with "FIREWALLS" built into their products. -=- Windows has a firewall to stop INCOMING connections -=-. By todays standard you would only require a 3rd party firewall in two situations.
A. Your running some sort of Enterprise Server open to the Internet for hosting various services.
B. Your on dial up as it creates a direct connection to the computer.
Other then that if your on broadband of any sort, so long as you have a BOX called a Modem/Router. It is your firewall, so you dont need one on the computer. That modem/router converts your connect to NAT. It's a long story.
Bottom line is this.
If Windows was meant to stop outgoing traffic, and could do so without causing problems. IT WOULD.
All the internet security packages fail due to having a firewall, when something goes wrong a BAD UPDATE, A VIRUS ETC.... when they damage the firewall component, NO MORE INTERNET/LAN
No file sharing, no shared printers, no network shares, no msn, no internet explorer....... = BAD
AVG Free Edition is solely a Anti-Virus and Anti-Spyware package using the Windows Firewall (as they all should) .... and works good.
It may lack parental control and fraud detection and other useless dummy things..... but in the same respect makes up for that in being less bogged down by those "extra's".
As a system builder/system admin and head tech...... I stand by this:
Every single machine that comes into be repaired, upgraded etc etc..... I automatically every since one REMOVE Norton, Trend, McAffee, Panda, Nod32 .....
Every single machine goes out with AVG Free Edition.
Occasionally we have the stupid customer that removes AVG and puts on Trend etc...... then rings up and goes MY INTERNET ISN'T WORKING SINCE I GOT IT BACK.
Did you put any third party security packages on? Like What? ....... Like Trend Micro or Norton 360 etc. "YES" ..... well there you go, remove it...... and if your lucky things will work again. Sometimes however when u remove it you need a special tool to fix your network so your internet works again.
Sorry for the long winded whirl of explaniation here. Point is.
1. Dont use anything that comes with a Firewall. Windows has one.
2. The less the better (Viruses/Spyware/Link Checking/Fraud)
3. Fast/Efficient/LESS ANNOYING
******* DONT USE ANY PRODUCT THAT SAYS IT WILL ADD A FIREWALL *****
