Security Questions People Ask

1. What is a good password?

There is a vast difference between a good and a strong password. 'Ab%98@#k*t5z' is a very strong password but is a bad password because it is very hard to remember. However, 'Blacck>Mang0s' is a strong as well as a good password because you can easily remember it. The other requirement we need to ensure is of keeping its length 10 or more.


2. Can  a Antivirus product detect all malware in existence?

This is simply not possible techinally, whatsoever the vendors may claim. However, some poducts may be better at any given time. The detection rate of even the best product may be not more than 85%.


3. Which is best anti-virus?

For commercial software go by the existing market reputation. But, be careful, a recently reported news mentions about an emerging antivirus product which induced malware and subsequently cleaned them to generate a good scan report. If you are using freeware then check for the reputation or popularity. Download these from a trusted source.


4. Is Antivirus required if use a firewall is used and vice versa?

Both have a different but comlimentary fuction. You require both to safeguard your computer. If a malware is able to breach your firewall then at least the Antivirus would have a chance to detect it.


5. What if the AV has not detected the malware and someone is remotely controlling or using my computer?

If your are a normal user then nothing much can be done to manually clean the offending software. The best option would be to go back to a previous checkpoint, or reinstall the OS after you have taken a backup. Before such a step, take a chance with the free tools i have listed on the right side of this post. Experienced users can use the tools mentioned in my prevoius post.


6. Enabling all the Browser security features has blocked my critical banking and email site?

There is no absolute '0' or '1' answer to this question. Depending on a users requirements and his web browsing habits vary he may have to customise the settings slowly over a period of few days. Disabling java may have led to your bank account page being rendered useless. You need to figure out this and enable java specifically for this site.
