Unsafe Googling, Layered Security For Your Computer and The Clampi Virus

Over last few days I've accidentallly connected to some really f'd up websites. I arrived at them by Googling for information about certain trojans and viruses. You may have seen the warning that Google sometimes places with a selection that a certain website may not be safe? Well, that warning does NOT appear on these renegade websites. Go figure!

I ran across one earlier this evening that pretends to be a place where you can find information on removing the Clampi virus from your computer. But once you've clicked on it you get trapped into a site that forces you to download and install a program. Here's what to do: hit ctrl+alt+delete and on your task manager simply kill firefox.exe or explorer or whatever your browser is. Don't go back to that website! Some of them leave a cookie on your PC so that if you re-visit them, a trojan silently loads on your computer! BE CAREFUL! There are trusted sites that you CAN download from. Look for symantec and other well-knwon trusted sites.

How to Implement Layered Security for Your Computer

Layer 1 is a personal firewall. A personal firewall is a software program installed on your computer that controls access to everything that enters or attempts to leave your computer. Think of it as having your own personal security guard at your house and he asks you for permission to let anyone enter the house or leave the house. I prefer Zone Alarm firewall. It's FREE!

Layer 2 is antivirus software. Antivirus software is another program installed on your computer that inspects the data on your computer for viruses, trojans and keyloggers. It does this by comparing the files on your computer with a known list of bad software aka signatures. The antivirus program also inspects data entering and leaving your computer, checks for virus signatures or uses an algorithm to detect suspicious data packets. You can purchase antivirus software, but again you can also get some very good antivirus programs for free. I like Avira Antivirus and Avast Antivirus. Don't use AVG Free, the free version does not offer "rootkit" protection which is a very common area of exploitation.

Layer 3 is protection from Spyware, Malware and Adware. These programs inspect data entering and leaving your computer and checks for known bad software signatures. If you are using Windows XP or Vista, then you are already running Windows Defender and are covered. If you would like additional protection you can download free programs such Adaware, Spybot Search & Destroy and Malwarebytes Anti-Malware.

Layer 4 is to make sure you are running Windows update on a weekly basis to ensure you have the latest security patches for your particular operating system. You should also check for weekly updates on each of the products you installed in the previous three layers. Most programs have a scheduling option so you can set it and forget it.

Layer 5 is scanning. You must ensure each of the products installed in the first three layers run a scan weekly. Again, most programs have a scheduling option so you can set it and forget it.

Layer 6 is passwords. All security threats don't necessarily come from the internet. Make sure the password you use to log on to your computer is not an easy one to figure out. Make sure the password contains a mix of upper and lower case letters, at least one number and a special character such as !, #, &,_ or *. Do not use your computer password for any online programs like your gmail, twitter, MySpace, Facebook, bank accounts, etc... And if you use your computer in public places like a library or coffee shop, you will need to change it often. You would be surprised how many passwords and pin numbers get intercepted by people looking over your shoulder.
