Software package that works to protect you from the dangers of the Internet is required. Do not be fooled when available in all kinds of programs such as anti-phishing, anti-spyware, anti-spam, firewall and virus scanner. However, many programs and functions impact directly on the PC performance.
If you want to surf more slowly then just use Norton Internet Security 2007, you only need to open a window for the WebBrowser to increase the CPU load up to 80%, whereas if you use to surf without Security Suite-load the CPU is only 20-30%. A comparison that is very surprising.
By using the security-suite, also increased the windows start about 23 seconds long. Consumption only on the use of RAM only software of this kind sparingly. Four applications Symantec, which is always active will take up to 40 MByte RAM. Better than the 2006 version which is very wasteful, and certainly did not pay attention to resource consumption windows.
With other security suites, you can even start again more slowly. Program Computer Associates (CA) to extend the windows boot process for almost a minute, because of a firewall, every time the WebBrowser open a new website will increase the burden of the system.
How many applications are needed to actually protect a PC ? McAfee Internet Security Suite-say at least 15 pieces and start all at the same time. All this program-at least-count of the number does not take too much RAM, but when browsing, supervision of all programs is always to increase the CPU load of 50%.
When the G-Data-Suite to check a URL is selected, the system load increased to 80% and go down again after the new site appears. In addition, the module 80 MB RAM spend more than "normal" as much as 130 MB. The PC will start faster than other programs, but until all applications in the Data-G-load and check the system, the time required is 30 seconds.
As an alternative to protect your PC, you can compare with the use of software-virus scanner AntiVir PE as usual. Freeware CPU is only a burden of 64% and offer best compromise between security and system load. AntiVir really only protect against viruses, but performance good enough.
Tips for other security also depends on the user when surfing, for example, does not open the original mail attachment, and always update the windows and not to click any links of websites that offer grandiose promises.
Happy Surfing.
