Antivirus software should be installed before Internet connection setup. Often viruses get in your computer before you download antivirus application or updates. Local network connection also should be disabled.
2. It is recommended to use antivirus that has real-time scanning functions. Such kind of antivirus software requires more system resources but provides more reliable protection. Viruses will be caught ‘on the fly’ and will not have time to penetrate the system.
3. Use ‘on-demand’ scanner regularly. Real time scanners monitor only confined number of ‘points’. But some viruses get in computer using security vulnerabilities that are not protected by ‘on-access’ scanner.
4. Don’t use more than one antivirus at the same time. Such situation can cause conflicts that will slow down your computer. Besides, solutions from different vendors may mistakenly take each other’s anti-virus databases as viruses.
5. Update your anti-virus databases as often as it possible. For example, ESET Nod32 bases are update three-five times per day.

When you are surfing the global network uses opens a number of ports. The most of software applications are intended for using of fixed port. As you can see on this picture Interne Explorer uses 80 port. Mail delivery applications such as Outlook and The Bat! use 25 and 110 ports. If you install Emule it will open 4662 and 4672 ports. Thus I computer is not secure because every application can open any port and transmit data by way of it. Besides, any external application also can connect to these ports. For example, I-Worm.MyDoom trojan can infect you PC. It opens 3127 port and hand over your private information. To reduce this threat and to monitor all ports there is some special applications. To reduce such thread you should close ports that you don’t need. There is some ways to it. For example to use Windows Worms Doors Cleaner. It is easy to use but it gives an opportunity to close only 135-139, 445 and 5000 ports. But to set up more reliable protection you should use special applications such as Firewalls. In next posts I’ll describe how to reduce this threat by means of such firewalls as Outpost Firewall, Kaspersky Internet Security, ZoneAlarm PRO, Comodo Firewall and Kerio Personal Firewall
PS Here you can see the list of common ports and to check them.

Usually we use a lot of different services and most of them ask you to inter your unique password and username. Some people use the same combination for all sites and services they use but it is clear that such method is not reliable. Fraudsters can still your combination and act like you on every site. So we have to do smth with the great number of passwords that we use.
There is some software applications which store you passwords but they have a number of disadvantages – for example, you can not use them when you use not your own computer. It is more secure and comfortable to use online passwords storage services. I know that there is a number of online password storage services which are reliable and easy to use but I use this one.
Clipperz - This service is very easy to use and provides a lot of opportunities. You can create different cards for different sites. There is also Direct Login function – it creates special links. Clicking them you can directly login to any site without entering password/login combination. If you are Firefox user you can use this service in sidebar window. There is another interesting feature – disposable passwords. You can list them and to use in the place were it can be stolen for example in a library or Internet cafe.

Kaspersky Lab has just reported about detecting of three variants of new trojan application for mobile phones. It is Trojan-SMS.SymbOS.Viver. This spyware sends paid SMS messages to premium number. Thus money is transferred from users account to fraudsters account. This kind of trojan applications is not so new. Similar applications were detected last year. They are able to run on almost every mobile platform. But Viver virus is assigned only for Symbian mobile operating system. Thus it is first trojan-SMS virus for smartphones. The analysis shows that this virus is distributed by means of free warez sites and looks like useful Symbian applications such as media players, photo editors and etc.

I have to note that all free antivirus applications doesn’t guarantee maximum security and defend your computer only against the most widespread viruses. It is said that more than 200 of new scumware applications appear each day. So the key factor is regularly updates. Unfortunately in case of free antivirus applications doesn’t give such opportunity.
There are two kinds of antivirus software. The first one is “on-demand”. Such applications are recommended for those users who don’t use Internet and email and don’t copy too much files to their computes. You can use “on-demand” antivirus only to check new disk or storage device. The second type is “on-access” applications – usually they include “on-demand” scanner but have also special mode which monitors all processes. Such application are more effective but can slowdown your PC (it is not of current importance for present day computers).
Among “on-demand” scanners I can recommend Bitdefender. You can find free version of this application on official web site. Virus definitions bases are updated regularly. Due to this Bitdefender is one of the best of free antiviruses of such class. According to some specialist it is able to detect more than 88% of all viruses.
Another free “on-demand” antivirus is ClamWin. It is assigned for Windows. It can not delete infected files but can move them to “quarantine”. It also can integrate with Internet Explorer and Outlook. It is said that it detects 48.44% of all known viruses.
“On-access” antiviruses have more opportunities. For example avast! 4 Home Edition. It has so much features that it is difficult to believe that it is free) This application supports Windows XP Professional x64 and has an opportunity to monitor web traffic. Virus bases are updated regularly. It detects about 79% of all known viruses.
The next antivirus is developed by German AntiVir. AntiVir® PersonalEdition Classic has no such impressive list of features but nevertheless it copes with a task. Antivirus bases are also updated very often. It is said that it detects 84.5% of present day viruses.
The last antivirus application is AVG Free by Grisoft Inc. . It is rather famous and updates its bases some times per day. Unfortunately according to research the percent of detected viruses is only 54. But it has very nice and usable user interface.

This information is transmitted back during next site visit. Main functions of this technology are

1. session organization for online shops, forums and other interactive systems. In that case cookies contain unique user ID.
2. different user’s parameter keeping.
3. user’s identification in such systems as rating systems, counters, banner advertising systems, online polls and etc.

For the last time cookies technology attract a lot of attention of infroamtion security experts. The main reason is that cookies can contain private infroamtion and can be stolen by means of spy applications.
Here is some ways to steel this information

1. Сross Site Sсriрting This method is based on including trojan code in legitimate web page. This script transmits cookie to fraudster.
2. Web browser vulnerability
3. Trojan applications using. This application amylases cookies and transmits information to malefactor
5. Using of public computers (for example in libraries). A lot of users don’t care about deleting cookies after using such computers.
6. Cookies interception by means of network traffic analysis tools.

To reduce cookies theft threat you have to apply these browsers settings

Internet Explorer

Medium position of this switch means that your browser blocks some cookies (counters, ratings). Maximum position means that your IE blocks all incoming and outgoing cookies. Due to “Sites” button you can specify exclusions.

There is also “Advanced” button. Here you can stop automatic cookie handling and specify browser activity for first-party cookies and exterior ones. It is also recommended to allow switch on session cookies – they are stored only for a session time.

Mozilla FireFox

The settings for FireFox are little bit differ. You can allow or disallow cookies. You can allow receiving of cookies only from that site you are browsing (it analogue of exterior cookies blocking system of IE). Besides you can set expire date. That means that after customized duration all information will be automatically deleted. There is special option which deletes cookies files after FireFox window closing. By the way FireFox supports special hotkeys combination which helps you to delete all private information in a matter of seconds. It is Ctrl+Shift+Del.
