Computer Security and Virus Protection 101

Sunday, July 5th, 2009

It is essential when surfing the net to have effective computer security such as a solid anti virus protection suite. In fact, surfing the net without anti virus protection is like walking through a hospital without having an immune system. There are threats in the thousands from minimal nuisances, like pop ups and add banners to very severe viruses and worms that can completely and permanently disable vital functions, such as Internet browsers, parts of hard drives, destroying even the best of computer brands, including, Dell computers as well as important data. 

There are many different types of malware and viruses, as well as different types of security software that can protect, detect and remove these threats. The best anti virus software will have real-time or drive-by virus and malware protection that will alert to and block malicious sites and downloads when surfing the web. There are many cheap virus softwares that are very effective at preventing virus infections.

Malware is short for malicious code software (mal-ware), which includes any and all forms of malicious code designed for destruction, advertising and other schemes. Malware is the term under which all Internet dangers fall, such as viruses, worms, spyware, adware, phishing, tracking cookies and rootkits.

Computer Viruses – 2 Worst Threats

Viruses
Computer viruses range from intermediate to severe in danger levels.There are tons of different viruses with new ones being born everyday. Viruses are codes with malicious intent that can attach themselves to computer programs and cause damage to the system and data. Computer viruses spread fast and can easily cause lots of damage. Including potential destruction of operating systems and data. The Trojan horse has been one of the worst types and has several variations and forms that are some of the most damaging in computer viruses. Recently a new virus reared its ugly head, called the Conficker virus.

Computer viruses can not only disable major computer functions, such as Internet browsers, they can also destroy data and completely lock you out of your system.

Rootkits
Rootkit are especially dangerous because they actually hide the existence of Malware from computer operating systems and from users. Rootkits create stealth program codes that run at a lower level than the user can see with most below average anti virus software. 

Not all anti virus software have rootkit protection so it is important to choose one that does.

One thing to keep in mind is to never surf the Internet or have an open connection to the Internet without a solid computer security virus protection suite installed, up to date and running on your PC. The best protection against computer viruses is prevention, early detection and removal. A good anti virus software has an accurate and up to date virus database and can detect, quarantine and remove malware efficiently. Another crucial

It is much more difficult to remove viruses if infection occurs than to protect against it. This is why it is crucial to have real-time or drive-by protection. This is essential as a real time scan is always running when surfing the web that will alert you to and block bad sites from adding viruses to your computer. This is not always standard with all anti virus software and should be a part of any good virus protection suite.Nothing is more essential to computer safety than a good anti virus software program.

Data Loss Emergencies – What Do They Actually Cost A Business?

Wednesday, July 1st, 2009

Data loss emergencies can hit any business without any prior indication of a potential problem. Sometimes data loss issues can be nothing more than a business hiccup and not to much data is lost, or the lost data can quickly be reworked  to get the situation back to normal. Conversely though large data loss scenarios can have an devastating effect on a business and the more employees they have or the more reliant they are on their IT infrastructure, then the bigger the problem.

If a main raid server has gone down and this is used to house the company's customer relationship management software then quite literally business can stop , especially if the CRM system is principally used for sales or the company employs a large sales force.

The effect will of course impact larger companies more than smaller organisations but the effect of data loss can still be quite devastating none the less.

If the business has had the forethought to put a disaster recovery plan in place then this can be quickly be implemented to get your business into action but if you do not have one, or have completed you business continuity plan but have simply not implemented yet then the effect of the data loss can be quite far reaching.

So what is the cost of a data loss disaster? This is a question often asked by smaller business as they need to establish a sensible return on investment in order to justify the cost of setting up a plan. Unfortunately the return of investment is a negative one in most cases, that is unless there is a data emergency,  then there will be no return on investment. There will on the other side of the coin though be a large risk reduction. A good measure that could be used for a sales organisation though could be loss of potential sales.

This can give very clear indicators as to potential revenue loss versus business down time and business continuity investment. For many organisations the loss of a days sales could have a very impact on cash flow and for larger companies potential loss could have an even greater effect.

Cost of lost sales is only one of the aspects that can be measured but other costs need to be taken into consideration as well many of which can be swept under the table if not factored. These could include the actual cost of employing a data recovery company in the first place or even punitive fines for missing contractual deadlines depending on what industry your business is in.

As well as measurable costs a company also need to factor intangibles into any return on investment or risk reduction calculation. Typical factors here could include activities such as re-population of customer CRM systems, additional management costs and business costs of running temporary as opposed to automated IT systems etc.

Another critical factor that should never be overlooked in the event of a data emergency is the restoration of the data. In many cases data can be irrevocably lost due to bungled attempts at recovery by inexperienced IT technicians.

Also if you are employing the services of one of the  raid data recovery companies you need to check their potential methodology and ensure they will not work on the actual donor disks as it is crucial to keep the main data source intact at all times.

Specialist business continuity providers will have strict protocols in place to ensure the absolute integrity of the source data. Working on the original data hard drives should simply not be an option because if the file structure or data is compromised in any way then your business could experience total data loss.

Advertising sells well no matter the kind of activity, particularly since everyone claims to have the best products ever. Not only do producers insist to emphasize the quality of their products but there are also different analysts and ordinary people – consumers who come up with their own classifications of the different products on the market. This obviously occurs in the field of computers, laptops and computer components too. For one interested in classifications, the Internet is the best source for information on top ten laptops.

It is evident that each individual has his/her own preferences when it comes to computers and laptops.

The size is an important factor to analyze since people with jobs that require travel need small, light models, even the tiny ultra portable ones of the Asus Eee PC kind. Other buyers closely analyze the RAM memory, responsible for data storage capacity, yet more memory equals more money. Last but not least, screen resolution also rules when it comes to deciding whether an item deserves to be part of the top 10 laptops chart or not.
