Most of the time, your computer is at risk of attacks from viruses and spyware when you are browsing the Internet. As soon as your PC gets infected by either of these two, you start to have an immediate effect. You will find that your PC is slowing down and at times it hangs in the middle with your monitor screen turning blue. Virus and spyware have other effects on your computer. Your firewall may have been affected, and suddenly, without your knowledge, it starts to send out strange traffic which consists of information relating to your personal data.

Virus attacks could take over your PC completely, so much so, that it starts to send emails to all the addresses it finds in your address book. A virus could initiate Distributed Denial of Service (DDoS) attack in large networks and could paralyze the whole operation. For detecting virus and malware in your computer system, you should have your PC scanned by web-based free PC scan which can detect various kinds of Internet security threats in your computer such as viruses, worms, Trojans, and spyware.

You can have your PC scanned by one of the free PC scan web-based utility found in the internet. The utility can help you to detect any viruses or malware in your computer which is perhaps slowing down your PC. The web-based tool scans for every known Internet threat that may have attacked your system. This may include various types of viruses, spyware, and other malicious software. Free PC scan also detects other files or software which is affecting the operation of your system, and also provides you with website addresses for you to download the missing security patches. After each scan, the utility provides you with a report on the various kinds of threats found in your system.

There is malicious free PC scan web based software which intentionally pumps in virus and spyware in your system when you request a PC scan. After the scan, you may find an odd looking tool bar appearing with your browser. A report generated from the scan would show you various kinds of virus that have been found in your system, and a pop-up will continuously ask you to purchase an anti-virus software to get rid of the various types of viruses found in your PC.

There are distinct signs when your computer gets attacked by virus or spyware. The system starts to get slow, takes a longer time to boot, an odd tool bar appears with your browser, and if programs like “Msconfig”, or REGEDIT do not respond, you can be sure that you have a virus in your system. There are several free pc scan that you can find on the Internet, and one of them can help you detect viruses and spyware in your computer.

You can find several user reviews on free pc scan on the Internet which may help you choose one. Virus and spyware do permanent damage to your computer, and you may lose all data that you have in your hard disk. Spyware could change your browser settings, or send away your personal information to a third party without your knowledge. Adware would continuously display advertisements on your monitor, popping up every time on your screen. Free pc scan is a way to know if your computer has been attacked by virus or malware.

Computer speed check tools are used for checking the clock speed of the CPU in your computer. You can download either the shareware or the freeware versions of the software and check various parameters concerning the speed of your computer system. You could also use one of several web-based computer speed check tools available on the Internet. There are two kinds of speed checks which are usually done on PCs; one which checks the CPU and other related speed elements in your computer, and the second one is the bandwidth speed of your ISP as related to your computer.

Computer speed check tools measure the actual performance speed of the CPU in your computer. Typical computer speed check software would indicate various aspects of your CPU speed parameters, such as, whether the CPU in your PC is over-clocked with your CPU clock speed running at a higher rate than specified. It would also indicate if the CPU is running faster than what it is rated, and whether the CPU is operating in its usual normal range.

Normally, the rated CPU speed is available on any Pentium 4 or later CPUs. The CPU of your PC should be running at this speed or below the rated speed specified by the manufacturer. Computer speed check software provides detailed description of your Level 1, Level 2 and Level 3 caches as supported by your CPU. Having larger cache sizes would mean a faster computer system. The memory speed is defined by how fast your CPU can access data in the memory. This indication is usually provided in megabytes per second. The software times this speed by executing large memory to memory transfer. Larger transfer rates would mean a faster PC.

The speed of your PC does not depend on the clock speed of the CPU in your computer. Computer speed check tools are used for measuring other speed related critical factors which go on to determine the overall speed of your system. They are also used for determining the speed of your network and your Internet access speed. Advanced computer speed check software provides you with a control panel and a separate graphical window in which the speed related parameters of your PC are displayed. The control panel lets you to change the parameter settings to view different test results under different conditions.

By making changes in the BIOS settings, the clock speed of the CPU in your PC can be adjusted. If you find the speed of your computer system is falling, there could be various reasons for its lowered performance. One could be that the CPU in your PC is not operating to its specified speed, or there could be something wrong with your data transfer rates. Computer speed check utilities may be used to find out various speed elements in your computer. The analysis done by the software can help you determine which speed component is affecting the performance of your computer.

The BIOS found in the present computer system can automatically detect the type of CPU being used in your computer. The CPU clock rate is also set by your BIOS through a multiplier factor. The speed related functioning of your PC depends upon the clock speed of the CPU in your PC and the data transfer rate between the CPU and memory. The “bus” system is responsible for transporting data, and the rate of transfer determines the overall speed of your computer. If the data transport rate is low, your PC will have a slower operating speed. Computer speed check tools, available on the Internet, have various features from just a basic utility to check CPU speed to providing extensive details relating to the other parameters in your computer which affects speed.

Appropriate changes in your BIOS settings can be made to set the multiplier factor in your PC which in turn reflects on the clock speed of the CPU. For example, a computer having a processor speed of 550 MHz, with a front side bus speed of 100 MHz, has its multiplier factor set at 5.5 for the CPU to work at 550 MHz. Before you make any adjustments to the CPU speed in your computer you should find out the various speed parameters which are governing overall performance of your computer. Computer speed check software has the feature to provide you with the entire information which you may utilize to diagnose the parameter affecting the performance of your PC.
