Computer Protection: Arming Your Computer Against Attacks

Up to 70,000 malicious files are uploaded to the internet every day. These threats to your computer can come in many forms such as Viruses, Trojans, Adware, Spyware, and Malware among others. In order to combat these threats you need to stay on top of them.

Anti-Virus programs are one of the most recognized types of protection software available. Typically these programs will scan for various types of threats, not just viruses. Unfortunately most people think that having a good anti-virus program is all they need to keep their computer safe. While it is likely that using this type of software will catch most of the threats, there is always the possibility that something will get through. In fact, this is quite common. It is very difficult for even the best programs to keep up with the amount of threats posted each day.

The latest strategy is to have a multi-layered plan that combines several programs to help protect your system. First, you should have a very good anti-virus program that includes “active protection” that continually monitors your activity. If your program has the option of quick and deep scans, then you should set up a schedule to perform a quick scan daily and a deep scan once or twice a week. Secondly, you should use one or more additional programs that look for more specific threats or infections like spyware or malware and run them at regular intervals. Thirdly, be sure the risk definitions for all of your programs are current and they are updating several times a day. Following this plan will give you an increased level of protection.

It’s easy to just accept the Anti-Virus ($160 value) program your Internet Provider offers since it’s free, but you may be surprised that some of the more popular programs offered are not always the most highly rated. I’m not suggesting you spend a lot of money because there are many companies that offer freeware programs. These programs usually have limited functions but allow you to upgrade to the purchased version for the added benefits. Remember price does not always determine quality.

Be aware that your Anti-virus program may also be one of the reasons your PC is running slowly. The better programs operate quietly in the background without any noticeable change in your system’s performance. They allow you to continue to use your computer while they perform their function. It is very important that you spend the time researching the different programs before making your final decision. When choosing you should look for good customer support, ease of installation/use and a good history of threat protection.  Cnet (http://reviews.cnet.com/) is a good place to begin your search.

If you decide to switch your Anti-Virus program, one very important task that needs to be done before installing the new software is to completely remove all traces of the original program. If you do not properly clean your machine of the old files they can create conflicts with the new program or with possible future downloads or updates. Your computer could become sluggish or even unstable. Remember, just because you “uninstall” the program does not necessarily mean all of the files have been removed.

No matter which Windows OS you are running, make sure you have the latest Service Pack and all the latest Security Patches installed. This is especially important with XP because Microsoft is stopping extended support for Service Pack 2. If you haven’t yet updated to SP3, now is the time.

If you choose to perform any of these tasks yourself, you do so at your own risk. Educate yourself or seek assistance before you make any changes to your system.

Remember to always follow safe and secure computer practices. DO NOT OPEN OR DOWNLOAD ANYTHING THAT IS NOT FROM A TRUSTED SITE OR FROM SOMEONE YOU KNOW.
