Hi Guys
I'm going to disagree with the lot of you here-- In all the years of using computers I've NEVER had a computer infection -- most Viruses come from dubious email attachments, dubious "torroentss and warez sites" and rather strangely are more often transmitted via CORPORATE networks than by home computers.
AV software is often more trouble than its worth --especially if you need to turn it off or remove it completely -- and what happens as will eventually happen one day if itself gets infected ---
"Who guards the guards"--- A clever virus would attack these programs in such a way that the program wouldn't of course report it itself. If I were a real Hacker I would be seriously working on this type of "project" anyway -- so I'm sure there are people out there doing just that. Looks like just the challenge for your next generation of Hackers -- they've come as long way from the initial "Phonefreaks" of the late 60's early 70's.
I'm not saying it's 100 foolproof but if you follow these simple rules you should get YEARS of Fun, safe and infection free computing and you don't need any AV software either.
1) Have your email client on a different machine to the one you use regularly. Connect to it via RDP / tight/realvnc or equivalent. If you only have 1 computer set up your email client on a VIRTUAL MACHINE.
2) Never open any attachment unless you trust the person who sent it.
3) NEVER EVER load up any program that offers to check your computer for Drivers, Registry cleaners, open ports, your IP address. (You can always find ouyt the IP address outside computers see your computer from by using faciulities in nyour Router --same with open ports - your router will tgell you what's open.
These sort of programs invariably at the best want you to suscribe to some type of paid service, otherwise they are full of SPY/NAG/MAL ware or worse.
4) Be 100% careful if you use torrents or other types of p2p sites for music etc etc. Quite frankly if your computer gets infected because you are trying to crack a key of something like OFFICE then you deserve all you get as there is a 100% very very good FREE open source version available at
OpenOffice.org - The Free and Open Productivity Suite which is as near compatable wiith microsoft office as you can get --and for 99% of people who aren't into heavy EXCEL macros even the spreadsheet is largely compatable with EXCEL anyway. - If you are a student then you can get a LEGAL copy ofg MS office anyway for a few dollars.
5) Test any "suspicious" software on a separate virtual machine. If anything doesn't work ort seems suspicious just dump that Virtual Machine.
After reasonable testing miograte the software application to a Real Physical machine.
6) if you do online Banking have that application on it's OWN separate virtual machine with NO OTHER APPS on it other than Internet access.
7) Block known "Bad sites". I access the Internet via a Linux server which keeps track of my access sites -- I block "bad sites".
8) regularly do the Microsoft updates -- these ARE worthwhile doing .
9) Keep plenty of Backups. Can't stress the importance of this one enough 10 ) Block ALL POPUPS and be EXTREMELY careful in clicking on anly link advertising anything. Internet shopping is fine but select what YOU want and follow that. Just don't willy nilly click on links. 11) Most home firewalls are a waste of time. Your Router is usually full of stuff that can do this (go into your routers admin mode - address something like 192.168.2.1 or 192.168.0.1 or whatever. There's all sorts of goodies to be found usually under advanced settings, and there are some very useful logs so you can see any inbound / outbound stuff taking place when you don't expect it.)
Whilst this stuff is not 100% foolproof it's kept my Computers virus free and I don't have to use loads of bloated AV software.
I also don't use social networking sites like you tube / facebook etc so I can't say what the potential for infection is from those site however if you want to use these go ahead or as they say "whatever floats your boat"..
Most of this will be 100% heresy to a lot of people out there but its kept my machines running OK and Virus free so until I experience trouble I'm sticking to these simple rulles outlined above.
In any case most of the infected computers found in corporations already have AV software running -- so it shows that a determined Virus writer can bypass AV software. There's always a lead time of a few weeks between a new Virus appearing and the updates to code to defend it so what's the point anyway.
If you backup your machines once a week just restore the whole kybosh to a period BEFORE the Virus was "released".
A Final remark -- Why I don't like MS doing AV stuff is that it might be another "backdoor" method to check on what version of Windows you are using.
This coulld for example stop the literally 100'000's of users of Build 7022 --like me
