Removing browser hijacks, Virus's and Spyware
Prevention continued, and conclusion
Increase security with a firewall:
A firewall of some description can be very useful. Especially if you have a permanent connection to the net. A properly configured firewall will prevent unauthorised access to your machine/network while allowing you to browse to your heart's content. There are a few different options available. A hardware firewall.
You can find these inside routers, broadband modems and similar devices. They tend to be plug and play but can be configured if needed. A firewall on a separate computer.
A firewall on your own computer.
This is more for protecting a network. The computers on network would get their net access through a single server with a connection to the outside world. A connection sharer of some sort. There are a couple of different paths you could go down here. Some examples are a dedicated firewall/connection sharing computer. One popular setup for this is Smoothwall, Here
Smoothwall is based on Linux and can be configured across the network. A similar approach would be Windows 2000/XP with Internet Connection Sharing. Not everyone's kettle of fish but still a possibility. A firewall for the DIYers would be more along the lines of a Linux box with connections to both your network and the internet. The DIYer would write up a set of rules using something like iptables, IP Tables
that would specify what data is allowed in and out. A different option for DIY firewalls is Network Address Translation or NAT. NAT covers connection sharing and firewalls in one. NAT can be easy to set up and just works. A good page for info on setting up NAT can be found at Netfilter
Regular virus scans
Probably the easiest to keep an eye on this would consist of a program you have installed and have running in the background. A popular firewall for this sort of use is Zone Alarm. A free download is available at Zonelabs
There is also a Zone Alarm Pro which is more configurable and includes "Powerful Identity & Privacy Protections". A 15 day trial download is available, if you want to use it after that you'll need $US39.95. Windows XP has a built in firewall but it isn't very good to say the least. Currently it is best to use a seperate program. Part of Service Pack 2 is a greatly improved firewall.
If you do nothing else regular virus scans are a must. Your antivirus software should be able to schedule scans so you don't have to remember to run them.
Speaking of software Microsoft is working on an anti-spyware program called Windows Defender. It's based on Giant Software's Antispyware and at the moment is currently Beta 2. Early reviews are coming out very favourably for Windows Antispyware and not just for the amount of spyware detected but also for it's look and ease of use. One drawback though is that it will require a subscription fee while other products like Spybot and Adaware are still completely free. If you want to download the beta and check it out it can be found at Microsoft Website# Warning
Do not use Spyware Eliminator from Aluria Software. Aluria has partnered with spyware company WhenU and removed WhenU's spyware from their spyware definitions. As a result Aluria's products, including Spyware Eliminator, regard WhenU's spyware as safe and will NOT remove it. More info can be found on Slashdot Here
