Trojan Horse PSW.Agent.Q

AVG found 2 copies of the above on my m/c yesterday, and moved them to the vault. After a reboot this morning it found them again (and put them in the vault).


Zone Alarm (I am a new user) has warned me today that "mcsmss.exe is trying to access the internet" A search on google seems to suggest that mcsmss.exe is (or can be) associated with various Trojan horses.

3 of the problems are given the path name C\WINDOWS\SYSTEM32\mdcms.exe, the other was found in Documents and settings....Temporary Internet Files\Content.IE5\EZJOT4XX\mdcms(1).exe

So my I please ask:

1) Has AVG solved the problem?
2) Is mcsmss.exe linked to the PSW.Agent.Q?
3) Should I allow mcsmss.exe access to the net?
4) Why did AVG find PSW.Agent.Q again the next day?

n.b I have scanned the m/c again this morning (after a reboot) and there were no problems.

Thanks in anticipation

John

You need to turn off system restore - run AVG again and then turn restore back on.

You will loose old restore points but that is the price to pay.

Have done as you suggested. Any thoughts about letting mcsmss.exe access to the net?

I've looked on my other XP computer and mcsmss.exe isn't there either. Is this something that I should try to delete; or should I permanently deny its access to the net in ZA?

I'll try deleting it from ZA and see what happens!

I've deleted it from ZA, but it's back! It seems to be trying to contact a m/c on my wireless network. I presume it should still have access denied?

I hope this is now sorted. Please see click here

Thanks to all involved.
