This week’s tech tip revolves around computer security. I don’t know how often I come across friends/family who have home computers which are completely unsecured. I imagine that most of the worlds virus infections are spread by people too cheap to buy virus protection for their home computers. To do a semi-competent job of protecting your home computer, you need to have a virus scanner, a spy-ware killer and a firewall. Here are some free options:
1. All-In-One solutions
You can help Symantec beta-test Norton Internet Security 2005 for free. Free, I guess, until the beta ends. [sometimes if you provide enough feedback companies give you a free copy of the software...]
2. Anti-Virus
Grisoft has a free version of its AVG anti-virus software you can download. It will scan e-mail and will automatically download new updates (so your anti-virus is always up to date).
3. Spyware Killers
Microsoft AntiSpyware (free). I run this in the background…it tries to prevent infection and also runs every night to detect infections for you to remove. I’ve found that Microsoft’s program is pretty good, but that it does miss somethings. Thus, I also use Ad-Aware Personal (free) and SpyBot Search&Destroy. Yes…I think you should run MS in the background and run Ad-Aware and SpyBot once a week to be squeaky clean.
4. Firewalls (don’t know what a firewall is/does? See Wikipedia.)
The latest version of Windows XP has a built in firewall. If you don’t know if yours is running, click here. Another highly recommended firewall is ZoneAlarm (free edition).
Conclusion…while these programs are not perfect, running all of them (at least one of each) will make your computer MUCH MUCH more secure.
[also...when you go visit your parents/in-laws make sure you copy all of these onto your USB thumb drive so you can install them on their computer.]
The comments are open if readers have other suggestions.
UPDATE: A reader pointed out that he’d suggest ditching Internet Explorer for FireFox. That is a pretty good point. I use both (I don’t know why). What I really like about FireFox is tabbed browsing. More details about FireFox can be found HERE.
