svchost.exe

by SLeizman88 / July 5, 2005 11:42 PM PDT

Every couple of seconds, Microsoft Anti-Spyware keeps popping up saying that an Application Change has been Blocked and it says that svchost.exe is a possible trojan, I did a Google search on svchost and it said that it is part of Windows. I did Spyware scans with no luck and I am currently scanning with AVG Anti Virus. Does anyone know about this "svchost" and what the problem could be?, I have Windows XP Home Edition with Service Pack 2 Installed.

Lots of trojans and viruses

use svchost.exe as a cover. That is because a typical system will have 3 or 4 "legitimate" svchost processes running, so the user will be less apt to find it.

The simple answer is it may or may not be a trojan or a virus. Due to this very reason, whenever I get a firewall alert that svchosts is trying to access the internet I automatically deny it, since it may not be a legit program.

If MSAS is flagging it, I suggest you use caution.

I removed it from Microsoft Anti-Spyware's detection list

So at least the notice stops popping up, In Windows task mannager in processes, it shows that 4 or 5 svchost.exes are running, some saying Network and some say System and some say Local Service.

This is Microsoft's explanation of what it is when it is legitimate.

http://support.microsoft.com/?kbid=314056

It also depends on WHERE it is located at. More explanation of that is here. (This is just an example)

NOTE: Svchost.exe is a legitimate program, which is not malicious, found in the System32 directory

I have XPSP2 and I also use MSAS and I have 5 Svchosts running right now and I have never had it popup on me which tends to make thing believe yours is malicious. What exactly have you scanned with so far?

fixed it i think

In reply to: Hi SLeizman88

yeah, right before I read this message I figured it out, the malacious one was located in the Windows folder (no subfolder) but the legit one was located in the system 32 folder, I figured this out on my own by clicking on properties because the legit one had the Microsoft copyright thing and the other didn't

Hopefully it won't

regenerate when you reboot. I would try that and see what happens and then do some virus and spyware scans to make sure it is gone.

Question about an old question
by colleen / January 16, 2007 4:02 AM PST
In reply to: Hopefully it won't

My Task manager is also showing that one of my svchost's is using alot of memory (actually more than my iexplorer) and I have gone into the registry looking for svchost/system 32. I have found 2 files labelled svchost which do NOT have system 32 attached anywhere within the files. In particular Windows NT shows SvcHost and has many entries such as:
DcomLaunch
Http filter
Imag svc
Local Server with alternate web client, browser, fast user switch, etc.

Should these 2 files be deleted? What makes me concerned is that zone alarm has Windows NT Logon Application looking for access to the net.

As always appreciate any and all help.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
