Office 2010 Key Microsoft Windows XP, antivirus te

As all of us know, Windows XP SP2 adds a brand new security characteristic - DEP (Date Execution Prevention Information Execution Safety), you possibly can protect your personal computer from viruses harm. In line with Microsoft's DEP technology, Intel and AMD have created a corresponding anti-virus CPU.


DEP

principle of anti-virus system when you upgrade to SP2, SP2's DEP function enabled to stop virus harm, due to the fact the DEP to monitor the numerous methods to quit the virus in the safeguarded memory place to run damaging code. DEP by way of the processor's NX (No eXecute) characteristic, search for the memory not explicitly consists of executable code in the data (these information are normally the source code with the virus), uncover the data, NX them are marked as . If soon after a program in memory, trying to implement these with So in the event you run a software that has been uncovered, DEP will probably be the virus code is marked as

If you would like to offer full play to DEP's safety, additionally to outdoors should really upgrade to SP2, your CPU should also assistance the DEP technologies. Presently typical 32-bit processor (for instance P4 Northwood, and so forth.) do not assistance NX, to assistance the technologies, the principal CPU 64-bit AMD processor (Athlon 64, AMD Opteron), and Intel's Itanium CPU, J Sequence P4 Prescott, is said to nVIDIA, By way of, Transmeta and other providers also program to add the NX in its chip technologies, but the speed of those corporations updates NX also sluggish, take a while just before the official start.

technique to enable or disable DEP

By default, SP2 crucial Windows programs and companies only to enable the DEP. But it is easy to also set up their own, so that all programs to the computer enabled DEP, so that you can stop the virus. In addition to Acrobat Reader5.0

example, the make all the programs and companies are enabled DEP, technique of operation is: Account login with administrator privileges SP2, and then click Double-click Enable DEP .

If you want to a program (for instance Acrobat Reader five.0) to disable DEP, you could click the over After the program is particularly susceptible to assault, the virus can sneak in to the plan, after which spread to other applications around the computer and contacts in Outlook, and ruin your individual files. DEP is enabled, if any, right after the program can't function appropriately, it is easy to obtain the software program vendor DEP-compatible model from the plan, if no such model is to disable DEP.


to assistance DEP, P4 Prescott

use of technologies in keeping with EDB Microsoft's DEP characteristic, Intel for their CPU developed technologies. Currently Intel P4 Prescott (mPGA478 with LGA775 bundle) or for that C0 core stepping D0, the newest J Sequence P4 Prescott core with E0 stepping. Only J Series P4 Prescott with anti-virus purpose, only it certainly help EDB technology to fulfill the SP2's DEP antivirus feature that makes it possible for for buffer overflow (buffer overrun) Vulnerability in the design from the virus fail to stop their replication and unfold to other techniques .

If you use a P4 Prescott / Celeron D (C0 stepping core) processors, upgraded to SP2, you may uncover a deadlock in the Windows XP running program, startup screen, but don't put on P4 Northwood will have this trouble. This really is simply because SP2 can open P4 Prescott (C0 stepping core) contains the EDB features, but this type of CPU and also the execution just isn't EDB, EDB part of its inner energy transistor won't run, and as a result trigger the program to die lock.

To resolve this issue, Microsoft has introduced within the September 14 amendment to the related paperwork, we can visit Microsoft's official web page to download. English model of Windows XP users to download handle is simplified Chinese model of XP users to download deal with

to help DEP, AMD 64-bit CPU using EVP approaches

AMD 64-bit processors the very first to assistance Microsoft's DEP technology. To be able to meet the DEP, AMD and Microsoft to style analysis and advancement of AMD's new chips characteristic AMD 64-bit processors (including the Athlon 64/Athlon 64 FX / Athlon 64 cellular edition / Sempron mobile edition, etc.) will have the EVP. EVP and SP2's DEP feature technical cooperation, to avoid

Yet, AMD 64-bit processors inside the device following setting up SP2,Office 2010 Key, so long as your pc starts, the DEP feature, and configure the necessary driver files named Mpegport.sys hardware, if you utilize the Sigma Style Firm Realmagic Hollywood In addition DVD decoder software program will conflict with all the DEP. This really is since older drivers are some similar operation using the virus, so SP2 to error it for that virus, which bring about the DEP, trigger the pc to repeatedly restart. To solve this challenge, Microsoft recommends that consumers update the older driver, or disable decoding software program for your DEP, flip off the SP2 virus safety.
