Firewalls for Windows PC’s

September 23, 2007

 A few years ago firewall products such as Zone Alarm were very popular, and rightly so, as they protected your computer from external attack. Then when Windows XP Service pack 2 was introduced the operating system included it’s own built in firewall, so everyone tended to forget about firewall products. However, hackers are getting more devious. More and more people are on broadband and leave their PC on all the time (just waiting to be attacked by a hacker who wants to empty your bank account).


We have been looking at some of the firewall products available and they have improved a lot in the last couple of years. Both “Comodo Firewall” and “Kerio Personal Firewall” are impressive products, far more sophisticated that the Windows XP built in firewall, and they offer a good level of protection. The best part is Comodo is totally free, and the Kerio product comes in both free and paid for versions (the free version looses some the the more advanced features after the initial 30 day trial).

It has some nice features, like the ability to recover files with lost headers, and to recover partitions even when the boot sector has been lost or damaged.

A couple of interesting IT questions and answers on

April 10, 2007

I receive a couple of newsletter style emails every month from and one of them recently contained a “computer questions and answers” section.

 You can see the Questions and Answers on their website. The second and third questions were both very good questions and probably are relevant to the majority of small businesses. So it’s worth taking a look at these questions and the authors answers.

This got me thinking.  ASL Computer Services could run a monthly or weekly question and answer article on this blog.

How would it work? Small business owners send in their questions to me by email . I will then publish the first three received with an answer every month, or if it becomes popular every week. So let’s give it a try. Send us your IT questions by email and we will publish the first three received with answers (the questions will be published as Mr W from Daventry or Mrs T from Rugby to protect peoples identity).

The Problem of Viruses

January 28, 2007

With more and more PC’s being connected to the Internet on a permanent basis via broadband, and also networked together within your office or home the spread of viruses has become a major problem.

If you connect any PC without any protection to the Internet via broadband it can become infected with viruses within a matter of hours. Quite a scary thought.

A virus infected PC may cause you a number of problems:

  • It may infect your other PC’s in your office or home 
  • It can delete or corrupt your data and documents
  • It could damage Windows itself which may necessitate a repair or
    re-installation of the operating system 
  • Often viruses will search your PC for email addresses and then
    send itself to those people without your knowledge, thereby
    infecting your friends, customers, and suppliers machines with
    the same virus 
  • It may make your PC run slowly, which means every task you do takes longer

So how do you protect your PC?

  • Ensure you have a reputable Anti Virus program installed and that it has not expired
  • If your PC is for home use (not business) there are Anti virus programs available totally free of charge, so there is no reason to not be protected (Speak to whoever does your computer support about the free Anti Virus programs for home use)
  • Make sure your Anti Virus program is kept up to date with new virus definitions via the Internet.
  • It should be configured to monitor your PC in the background continually looking for virus infections
  • Scanning of all incoming and outgoing emails for virus infections should be enabled
    Perform regular scheduled scans of your hard disk drives at least once a week

So check your PC’s, both home and office, and make sure they are protected from viruses. Home PC users can download a Free Anti Virus program from the Grisoft AVG Free Edition website (for home use only).

For business use, or home PC users that want more features and greater levels of protection download and buy the AVG Professional Version.
