Hi all
The best and ONLY safe security system is IMO THE USER.
If you follow basic simple rules there is absolutely no reason why you should EVER have a problem with viruses / trojans / malware etc.
I've been using Winows machines since Windows 3.0 and have NEVER had a virus problem on a home computer (corporate / work machines is another matter).
False positives on Home Anti Virus software cause more trouble than the wretched programs are worth. To me home AV software is a 100% waste of time and slows resources down horribly.
1) Don't open ANY email attachment unless you know who its from and trust them.
2) NEVER EVER run programs that offer to scan your computer for you - such as
Driver detective, Registry fix etc. - Some might be OK but once you let people mess around with the registry (Still a weak point in Windows) you've thrown away the keys to the kingdom.
3) Torrents --if you must use --USE WITH CARE and only D/L stuff with known decent trackers.
4) Unless it's a well known commercial site such as Acronis, Microsoft etc - don't bother with Trial / demo / other software "in development" unless you know and trust the developers.
5) Only use online banking where an EXTRA security pops up such as Barclays Bank in the UK -- and never give out logon details. Most Banks now if they are any good usually prompt you randomly to enter character x in you password a number of times -- the positions varying each time you use the service.
6) Password crackers are usually fairly powerless if you have special characters (especially fairly unusual ones) and lower case in them.
For example the icelandic letter eth (ð) doesn't get used much outside the country if at all - this is a good one to insert somewhere in your string. You need a multi-key combination though to enter it on a normal qwerty keyboard.-
7) install and test software on a VM before migrating it to your real machine. If you need the actual hardware test it out on a special machine that is DISCONNECTED FROM THE NET.
8) don't let kids EVER use a machine you need for work. I use a server which controls and logs internet site access - this machine is physically located in the loft so I'd know if someone was trying to physically access the server. which brings to point 9) - physical access - restrict who can physically access your machine --if you are in a workplace always leave it locked with a password required to activate it again.
10) use online shopping with care - check "phishing" warnings.
11) Keep firewalls switched on and DON'T OPEN unnecessary ports. Always check your routers logs regularly.
If you follow these rules you can junk AV software.
Hacking per se is now old hat and not cool any more -- these guys have moved on to "Phishing", Identity theft and extortion by threatening Denial of Service attacks to service providers --much more profitable for them.
Home type AV software is trying to solve a 20th century problem in a 21st century environment - so its bound to be a loser however you look at it.
(Note this post applies to HOME AV stuff -- corporate firewalls and protection is necessary but that's a whole different ball game).
