How to Prevent PC Virus Infections

Believe it or not, no matter how good an anti-virus software program is, it is important for you to have knowledge about how you can prevent your computer from getting attacked by viruses. Do not forget the saying that knowledge is power. Below are some of the tips that you can follow to ensure that your computer does not get a virus infection.

1. Update your anti-virus program and detection database. This is the most common reason why users get a PC virus in the first place - they do not update their programs to detect and prevent the latest viruses, spyware, trojans, and other malicious stuff out there in the internet.

2. If you find an email from someone that you do not know and there is an attachment with the email then never ever open this kind of mail. You should also not open an email if you do not know what the attachment is, even if the mail has been sent by a friend. The reason why you should do this is because of the fact that your friend may unknowingly pass on an infected virus to you through any forward mails with attachments. If you are using Windows then you should set the option to “not hide” file extension from “hide file extension”.
3. You should add your own email address and save it in you address book. This is more of an alert if your computer is infected and a malicious program starts sending spam and viruses to people in your email list then you will be alerted of this when an email is sent to you. 
4. Before you run cookies and ActiveX, set them to prompt you. By doing this, you can effectively prevent your computer from being infected by viruses. When you find ActiveX in your emails then chances are that the emails contain virus.
5. Get an anti-virus program that is not just popular among people all over the world but it should also be effective in preventing viruses from attacking your PC. Make sure that the program puts out updates on a regular basis so that you will have an up-to-date anti-virus program. Some of the programs that you can consider using are Kaspersky, McAfee and Norton. Always remember that if the anti-virus program that you are using does not puts out updates on a regular basis then it is not effective in protecting your PC.
6. If there is a program that you wish to download but you are not sure whether it will be safe to download it or not, then you should not download it.

By implementing these simple tips, you can decrease your PC’s chance of getting infected.

How to Fix a Virus Infected PC

There can be no doubt that computer viruses make up a significant percentage of most system wide security breaches. Due to be reactive way in which most antivirus software developers function, no antivirus suite is ever fully up-to-date. Instead, updates are issued to the virus database once new viruses have been identified and a cure has been developed. For this reason it is important that people understand the steps they must take to clear a virus infection from an infected PC.

The very first thing that should be done when you suspect your PC of having been infected by a virus is to ensure that every available security update is installed via the Windows Update website. The reason for this is because Microsoft often release updates to the malicious software removal tool, as well is updates to fix security holes within the operating system itself.

Once you have installed all operating system updates you should then ensure that your antivirus software is fully updated. You need to be aware that it is not just the virus definition database that will need updating, you will also need to ensure that all program updates are installed an active.

Now you have updated the system software you need to take measures to clear down the infection. The very first thing that needs to be done is a full and exhaustive virus scan of the entire PC. Do not rely on the dynamic virus detection of your antivirus solution in this situation; instead you will need to instruct your antivirus software to perform a full system scan. This can take some time, and is properly best to run this scan overnight. Once this scan is complete it is highly likely that you will have one or more virus warnings, simply follow the prompts pursued by your antivirus software to deal with the infection.

In a very few cases, especially with extremely new viruses, the antivirus solution you have chosen to use may not pick up the infection. In this case you will need to find another way to rid yourself of this troublesome virus. What many people tend to do is try an alternative antivirus software solution, and in many cases different antivirus software will pick up the virus. If all else fails, the only way to be sure that you are completely rid of a virus infection is to reinstall your operating system and application suite.

How Can You Ensure That Your PC Is Secure?

You need to be careful when it comes down to protecting your data in the computer. As long as your computer gets internet access, the data in your computer is at great risk from web browsers and spyware. You can get rid of the threats to your computer by making sure that it is safe and secure. Believe it or not but hackers can get access to your computer and get important information from you. Moreover, hackers can also place viruses in your computer.

Follow these tips to make sure that your computer is safe:

• Create strong passwords for the different users of the computer. The password should contain a minimum of seven characters that should include lower case, upper case and it should also be alpha-numeric. To create a strong password, you should not just use uppercase in the beginning. You should also use upper case in the middle of the password.
• Your computer system should have a firewall installed so that hackers will not be able to break in to your computer. Basically, a firewall is a hardware or software device that is designed to find out remote or unauthorized access to your computer. It also prevents the hackers from accessing your computer. The firewall will also note down the address from where the hacker is trying to access your computer.
• You have to install anti-virus software in your computer in order to prevent viruses from attacking your system. Make sure that you scan your computer with this software program to ensure that your computer is free from viruses.
• You should be very careful when it comes to adware and spyware. These are programs that gather information and advertise products; these programs are installed in the system without the knowledge of the user, for the purpose of marketing.
• If your computer has ‘hidden shares’ then make sure that you disable this. Generally, this is present in Windows XP and Windows 2000. If you do not disable this then important data from your computer can be copied, altered or deleted.
• You have to change or modify the security settings of your computer. Computers are occasionally infected with ActiveX code. You can prevent any problem from arising by changing the default security of your system to high.
• Instead of using the popular web browsers such as Internet Explorer or email clients like Outlook Express, you should make use of other options such as Mozilla Firefox and Eudora, to name just two.
