Every time i turn on my computer, my firewall McAfee keeps popping up with "Buffer Overload Blocked". It is a Program called svchost. When i search it on windows vist it comes up with it but when i click on the Program it does not open. Can someone please tell me what it is, and weather i should allow McAfee to trust it. The file description is "Host Process for Windows Service, and its company is Microsoft corporation.

The pop up just suddenly started once when i turned on my laptop, i might have installed some vista update. Can someone please tell me what it is, and weather i should allow McAfee to trust it.

Answer 1

McAfee is like the retarded cousin of Anti virus software that nobody likes... Yes McAfee should trust it, and no you shouldn't have to tell it to trust it. Go look at what Avast Anti Virus has to offer. I promise Avast will never give you trouble over a Windows Process. lol -.- Avast uses only one process to run so your computer will run a lot smoother with it on board instead of Old Mc. Plus Avast is free for a private user.

When you install SP2, Pop-up Blocker is turned on in Internet Explorer and set to the medium setting, which means it will block most automatic pop-ups. The default settings for



the pop-up blocker allow you to see pop-ups that are opened when you click a link or button on a Web site. Pop-up Blocker will also play a sound and show the Information Bar



when a pop-up is blocked. You can adjust these settings so that Pop-up Blocker works the way you want it to.

To change Pop-up Blocker settings

1. Open Internet Explorer.

2. On the Tools menu, point to Pop-up Blocker, and then click Pop-up Blocker Settings.

Answer 5

Pop-ups can be classified as follows:

General browser pop-ups

Messenger Service advertisements

Pop-ups generated by adware and spyware

General browser pop-ups?

These pop-ups can be prevented by installing a pop-up blocker. Often times, these new windows display advertising that can interfere with your ability to see the content on the



page you're trying to read. Adding the Ad related Domains to the Restricted Zone in Internet Explorer is a good idea. Refer to the following MS-KB articles to learn how to stop pop



-ups from a particular webpage.

Windows XP Service Pack 2 now includes a built-in Pop-up blocker. You can read more about this feature, in the following pages:

Messenger Service Advertisements



If the title bar reads as "MESSENGER SERVICE" with gray Ads, then it the famous Messenger SPAM. This is applicable only for Windows 2000 and Windows XP. The



"Messenger Service" [different from Windows Messenger IM] is responsible for transmitting these text-based messages. While disabling the Messenger Service can stop the pop-



up ads, it's not sufficient in the security point of view. These messages arrive to your system because there is a way for someone to transmit data to your computer via TCP and



UDP ports [UDP ports 135, 137, and 138; TCP ports 135, 139, and 445 137]. This means, some intruder can do nasty things on your computer with these ports open.

The HIGHLY RECOMMENDED method to prevent these type of pop-up and to harden the security of your computer is to install a firewall application (such as Zone Alarm), or use



the Windows XP Firewall. Windows XP SP2 turns off the Messenger Service by default, and enables the Windows firewall. This blocks the ports required for Messenger Service



data transmission.

To enable the Firewall in Windows XP

For Windows XP SP2 systems:

If you're using Windows XP, and haven't updated to SP2, please do it immediately.

Click Start, Run and type Firewall.cpl

Select On (recommended) button, and click OK.

Never connect to internet without enabling the Firewall. Otherwise, there are fairly good chances your system gets infected. Finest example is the RPC NT Authority Shutdown



caused by Blaster Worm, which infects "unpatched" and "unprotected" computers.

Note: If using a third-party firewall application, you don't have to enable the built-in Windows XP firewall.

Pop-ups generated by Ad-ware & Spyware

Spyware cause the same effect as general browser pop-ups but they are usually powered by Browser Helper Objects, ActiveX controls which attaches to Internet Explorer and



contacts their servers without your knowledge. This not only means waste of internet bandwidth, but your private information may also be sent to someone. You need to treat any



outgoing connection without your permission, as a security threat.

Along with your anti-virus software, you need to anti-spyware tools such as Ad-Aware, Spybot Search & Destroy, Spyware Blaster at a bare minimum. You must update the pattern



files before scanning just like what you do for your anti-virus software.

Protection mechanisms

Use HOSTS file to block unwanted ad servers and sites that are known to spread malware

Increase your browser security settings. Visit the following link to learn how to protect the system from parasites.

(Site packed with full of security tips, advice to prevent parasites being installed)

Use an application-based firewall, such as Zone Alarm, Sygate etc. They alert you whenever an outgoing traffic by a new application is detected. By doing this, you are



preventing dialers, Trojans accessing the internet. Give equal importance to the configuration of the firewall. Assume your firewall as the gatekeeper, and only allow programs that



you want, to access the internet. You may then test the effectiveness of the Firewall (for inbound protection) using any of these websites. They scan your system for open ports



and vulnerabilities and advice you what action to take.

Answer 6

According to Microsoft: “svchost.exe is a generic host process name for services that run from dynamic-link libraries”. Could we have that in english please?



Some time ago, Microsoft started moving all of the functionality from internal Windows services into .dll files instead of .exe files. From a programming perspective this makes more sense for re-usability… but the problem is that you can’t launch a .dll file directly from Windows, it has to be loaded up from a running executable (.exe). Thus the svchost.exe process was born.



Why Are There So Many svchost.exes Running?



If you’ve ever taken a look at the Services section in control panel you might notice that there are a Lot of services required by Windows. If every single service ran under a single svchost.exe instance, a failure in one might bring down all of Windows… so they are separated out.



Those services are organized into logical groups, and then a single svchost.exe instance is created for each group. For instance, one svchost.exe instance runs the 3 services related to the firewall. Another svchost.exe instance might run all the services related to the user interface, and so on.

Answer 7

Well as most of us no comcast is going to drop mcafee and switch to its norton security system. This is due to hackers still being able to get throught the firewall. If you go to your comcast account you should have the option to switch from mcafee to norton for free

Answer 8

The Svchost.exe file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services part of the registry to construct a list of services that it must load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services allows for better control and easier debugging.



Let Svchost.exe through.

Answer 9

Svchost.exe is a system process. So allow mcafee to trust it, unless you want to break your PC. Then go ahead.
