How to Protect Your Computer From Viruses

computer security virus tips

With millions of computer users browsing the web at any given time, there are plenty of targets for malicious coders. While computer experts don’t always know why coders choose to build harmful computer programs, the fact is that it happens all the time. Computer viruses can steal personal information, interfere with normal operations, attract spam and even shut down your computer’s hard drive. Protecting your computer is critical for browsing success.

Start With the Basics

Most computer systems come with security features already in place. For example, the Windows operating system is packaged with Microsoft Windows Security Center. When you first open, boot up and register a new computer, you should make sure that this program is functioning. It will give basic protection against spyware, viruses and malware. In addition, a basic firewall is built into this program, providing additional protection and stops for potentially harmful programs. Upon activation, don’t be surprised if your security system needs immediate updating. Software that protects your computer needs regular and consistent updating to stay useful. Viruses are constantly being generated and the several-month lag between when your computer was made and when you first started using it can mean that the database the security system is loaded with is severely out-of-date.

Upgrade to Meet Your Needs

Many people operate computers for a long time with only basic protection in place. However, heavy computer users or those who have risky browsing habits can sometimes benefit from upgrading their virus, spyware and malware protection, as well as using a fuller-featured firewall; this is especially important if you use a networked computer system. Basic or free virus protection will still scan and update for viruses. Paid programs, however, offer more features, including ease-of-use and convenience features. The most important thing is to verify the publisher and make sure you are getting what is promised. Most well-known virus protection programs, such as AVG and Norton Security, have reviews available to help you make your choice.

Learn About Spyware Risks

Spyware creates risks that many computer users are not aware of. If you are only protecting against viruses, you could be leaving your computer open to damage. Most people are familiar with spyware that initiates and attracts annoying ad programs. Spyware, however, can be much more malicious as well. Your shopping habits can be tracked by spyware. While not exactly harmful, some people consider this a breach of privacy. The worst spyware programs interfere with normal operations and can even track what you type, sending personal information to people who want to steal your identity. Some spyware redirects your browser to different web addresses, increasing your risks of virus infection and fraud.

How Viruses Work

The main difference between spyware and viruses is how they are spread. A virus reproduces itself and attaches to any document that the computer sends, while spyware can be stored as a cookie or tracking code. A virus is most often found traveling with a piece of computer software, such as a document, picture or piece of music. When dealing with email, it is necessary to open an attachment to become infected, indicating that, in most cases, the computer user must somehow invite the malicious software to replicate on their system. Of course, most people have no idea it is there or what is happening. Some of the sneakiest and most harmful viruses actually masquerade as virus protection software, making them extremely hard to detect. Because of this, it’s crucial to be familiar with your particular virus protection program and know what it looks like and what the normal scripts and prompts are during operation. Viruses do some of the same things that spyware does; they just accomplish it differently. An active virus can steal personal information, generate ads or shut down your system, including the very virus protection programs that can fix the issue.

Take Steps For Protection

Like anything, the best way to protect against viruses is to be educated. Become familiar with what malicious software may look like. If you get an email or are asked to download a file that you don’t recognize or looks suspicious, do your homework. Research virus protection, spyware, malware and firewall programs and use them to their fullest capacity. Set the software to update and scan automatically to make sure that the system is constantly monitored. In addition, regularly check on the databases published by various virus protection services; many will provide lists of symptoms and risks, as well as the standard way the file gains access for no cost to the public

Get Rid of Boot Malware with Microsoft’s System Sweeper

Have you ever booted up your PC only to get a black screen? When this happens, something’s clearly wrong, so you’ve probably tried a number of steps to get your PC running again. But what should you do if those solutions don’t help? Try using Microsoft’s System Sweeper to get rid of the malware that’s messed with your system’s boot files.
Microsoft's System Sweeper
System Sweeper is a boot-up recovery tool that performs an offline scan on an infected PC to identify and remove rootkits and other advanced malware—without booting into Windows. You can also use System Sweeper if you cannot install or start your antivirus solution, or if the installed solution can’t detect or remove malware on your machine. Based on Microsoft Security Essentials, System Sweeper should get PCs back on track; however, it’s important to remember that System Sweeper is not a replacement for an antivirus solution that provides ongoing protection.
Let’s take a look at how to run System Sweeper when you cannot start your PC and quickly get rid of malware.
Step 1: Download System Sweeper. Go to Microsoft Connect to obtain the beta version of the program. Make sure to choose the right version (32-bit or 64-bit) depending on what your infected system is running. The supported web browsers are Internet Explorer 6 or higher, or Mozilla Firefox 2 or higher.
Step 2: Create a bootable recovery CD or USB thumb drive. System Sweeper can be installed on both a CD and on USB flash memory. You should first get a blank CD or a reformatted USB thumb drive with at least 250 MB of space. Then, go to your Downloads folders, and run the “mssstool32” or “mssstool64” files depending on which architecture you have. System Sweeper will download the latest antivirus signature files onto the disk, and then burn them onto either the bootable CD or USB thumb drive.
You should then insert the CD or plug the USB key into the computer you’re trying to clean up, and make sure to boot from the CD/DVD drive or the USB port. To do that, go to the BIOS of the machine by pressing DELETE, F2, F12 or another special key repeatedly right when the PC is turned on. Then, go to its boot section, make sure that the “Boot Priority” is set to either CDROM (DVD) or USB, and restart the PC.
Step 3: Use System Sweeper. Your PC should ask you to “Press any key to boot from CD or DVD”—follow this advice and wait until the recovery environment is loaded. Once System Sweeper appears on the screen, hit “Start full scan” to scan all of the hard disks for viruses and malware.
Once you’ve completed these steps, you can let System Sweeper run its course, but keep in mind that it might take a while depending on the amount of data. It will be worth the wait to enjoy a clean and bootable PC again.

You Can Check A Suspicious Website for Malware In Your Browser

If you open up your web browser and type the following in the address bar;
AND, after the “equals sign” type the web address of any site, that site will be checked against Google’s updated lists of suspected phishing and malware pages. It is a handy and quick way to help verify your suspicions of a potentially bad site.
This is all part of Google’s Safe Browsing Service.  The goal of this service is to:
  • Warn users before clicking on links that appear in your site when they lead to malware-infected pages.
  • Prevent users from posting links to known phishing pages from your site.
  • Check a list of pages againest Google’s lists of suspected phishing and malware pages.
For example if you wanted to get a report on For our pc, you would type the following in your browser’s address bar and hit enter.
You will then get the following diagnostic report from Google:

An Online Lightning Fast Virus Scanner


To add another tool to your arsenal in the fight against malware, be sure to visit BitDefender’s QuickScan.
BitDefender’s QuickScan
BitDefender’s QuickScan is an online tool which uses a technology they call .in-the-cloud. scanning technology which is capable of detecting active malware in less than a minute.
BitDefender’s QuickScan
The benefit of this technology is that the scanner uses online scanning engines that only uses a fraction of system resources needed to perform the scan; PLUS,the entire database of signature updates, etc… is maintained online by BitDefender.
One thing I do want to point out here and this is important:
BitDefender’s QuickScan is a tool that is designed to “detect” malware that is already existent on your PC, which is already active in memory or present in files that are run at system startup. In other words this tool is used, as a second opinion, to determine if your system is infected or you have suspicion that your system is infected.  It is not designed to provide real-time protection; but, again it is another tool to add to that arsenal in the fight against malware.  Thank you BitDefender for helping keep us safe…
