This is a very short article so there is no way I can cover all the problems you can experience with your computer. I will go through only 4 common computer problems and how you can solve these computer problems.

The first common computer problem is virus (or general malware) problem. Virus is a common term used by computer user to mean any software that creates problems such as slowing down your computer, displaying annoying pops ups, or disconnecting you from the internet. Solution is to download antivirus or antispyware programs to protect your computer.

The second common computer problem is performance issue. This a bit similar to the above because virus can slow down computer performance. The solution to a slow computer is to optimize the memory by removing majority of your startup items and background services, upgrade your memory, and perform different types of tweaks to improve computer performance.

The third common computer problems is how to upgrade the computer. If you have a old computer that you want to upgrade to the latest, the solution is to not be afraid because you can do it yourself. Once you find out the make and the model of your computer motherboard, you would be able to figure out the components required and you can make purchase of these components and add it inside your computer yourself.

The fourth common computer problem is hardware problems. The solution to this problem is to get an expert to fix this for you. Hardware problem such as broken screen, damaged motherboard, damaged power supply etc are not easy to fix by ourselves so we require an expert to do these for us.

Others problems include computer crashing, freezing, Windows errors, registry problems, drivers problems and so on.

For more detailed solutions to solve computer problems, it is highly recommended that you should visit Advanced PC Tweaker site. Here, detailed solutions on how to maintain and tweak computer will be discussed.

If you’re connected to the Internet (especially with an “always on” connection such as cable or DSL), you’re at risk for intrusion from hackers or with infection from a virus or spyware. This can happen without your knowledge. You can be browsing, logging on and off various web sites, etc., and be compromised. However, you can protect your computer from this type of intrusion by following a few simple steps.

Using Routers and Firewalls

If you don’t already have one, you should get yourself a router. This is important even if you only use one computer. This is a type of hardware firewall, which is the best kind. It will protect any personal information you have stored on your computer and will keep it safe. It will also protect you computer from being infected with various viruses.

Because hackers try to gain access to your computer by doing what’s called “port scanning,” a router can completely block the scans or at least slow a hacker’s progress down. Most hackers want to work fast and won’t waste a lot of time trying to get around a single router. Instead, they’ll move on to someone else who doesn’t have a computer that’s well protected and that can be hacked.

You can also use a software firewall. Oftentimes, your operating system will already have one included. One good example of this is Windows’ firewall. . All of today’s software firewalls have several packages to choose from.

In order to protect yourself from unwanted intrusion, spyware, viruses or hacking, you’ll need the following components:

- An antivirus protection program

- A spyware scanner and removal program

- An automated virus scanner and removal program

- A firewall

Antivirus protection program

An antivirus protection program will scan your computer for viruses and then will quarantine them or will delete them if it can. It will give you the choice, oftentimes, as to whether or not to delete or quarantine. There are many good antivirus program is available. You can also buy complete packages. Many ISPs also provide their own antivirus programs, so make sure that your ISP does not offer one before you purchase one.

Once an antivirus program is downloaded and installed, it will run in the background to make sure that your computer is always protected. Most antivirus programs will update hourly to daily. You can set them so that they will update automatically and therefore keep your computer protected with new definitions all the time. Again, this is especially important if your computer is “always online,” as with DSL or cable connection versus dial-up. If set up correctly, your computer will have maximum protection from new virus intrusions.

Being armed with the proper virus protection is the best thing you can do for your computer to keep it running smoothly and to avoid unwanted intrusion.

Spyware scanning and removal program

Spyware can be installed on your computer without your knowing it whenever you download something for “free” from a web site, for example. At its most innocuous, it’s meant to keep track of your browsing habits online; however, more malicious spyware can even give hackers the opportunity to access personal information such as credit card numbers, for example. Regardless, spyware is something that really doesn’t belong on your computer. Even if it’s “innocuous,” it can eat up system resources and slow down your browsing significantly. Simply put, it should be removed.

To do this, there are many spyware programs available, for free. Again, Windows has its own spyware component called “Windows Defender,” that does quite a good job of protecting your computer from spyware, including its installation. Other programs have both a paid version and a free version. Adaware does not protect your computer from new spyware, but will remove spyware once on your computer for free.

An automated virus scanner and removal program

In most cases, the virus scanner and removal program will be included with your antivirus software. Because your computer has the antivirus software running in the background all the time, your computer is protected from new viruses as often as it’s updated. Therefore, frequent updates will help ensure that your computer is not infected with new virus definitions. However, if a virus does happen to make it onto your computer, you’ll need a regular virus scan (usually daily to weekly) to make sure any viruses that have gotten on to your computer are removed.

As part of your antivirus software (generally), when you run the virus scan, the program will opt to either automatically quarantine or remove any viruses it finds or will ask you what you would like to do with them, depending on the options you set. In most cases, it’s probably best to go with the default choice the program gives you. Most of these programs tell you to let the program choose what to do with the viruses it finds.

A firewall

A firewall is your first line of defense against anyone hacking into your computer. There are many software versions available if you don’t want to use a router, and some are free to download, although most of these also have paid versions with more features. One of these which is highly recommended is PC Safe Doctor. If you are not a commercial user, you can get it for free by visiting the PC Safe Doctor site.

This software lets you set individual Internet access capabilities for individual programs, allows for automatic program configuration, and puts your computer into stealth mode, which makes your computer invisible to anyone else on the Internet. It also blocks intrusion to anyone trying to hack into your system automatically. A paid version also includes virus protection with PC Safe Doctor if you choose.
