Your problems could be due to a virus/malware of some kind that isn't detected by anything you have. Do you keep them all up to date? If yes then maybe the problem is a driver fault, if not then you need to.

In any case, if you download hijackthis, ( http://www.spychecker.com/program/hijackthis.html ) it will take a snapshot of your running processes and what's going on in your pc.
Unzip it to it's own folder on a permenant directory - e.g. your my documents folder, run hijackthis, click 'scan', then 'save log' when it's done, then paste the contents of the file it creates in here. Hopefully one of our experts will then be able to tell us if you have a virus.

Please DON'T fix anything yet - the log is a complete snapshot of your system, so most things will be legitimate.

hmm a couple of things concern me but hopefully a true expert will be along soon.

Do you use Sun Star Office? because this file C:\WINDOWS\SOINTGR.EXE is supposed to be in the sun staroffice folder, so it could possibly be a virus, but DON'T delete it yet just in case!

Also the limewire entry is p2p software that is a potential security risk - do you use it?

And after that I'm not sure about the nameserver entries - hopefully someone knowledgable will be able to help you out here.

why remove limewire ?
read this about a limewire user :



A lot of freeware are bad for your computer security, particularly those peer-to-peer programs like KaZaA, LimeWire, and Morpheus. These programs often install additional unwanted components such as "SpyWare". These components often remain in place even after the Peer-to-Peer program has been removed.

This happened to be because I was a music glutton. I downloaded LimeWire 4.07 and installed on my Windows XP. At first, this app seems to be quite promising fro what I wanted as a free music getter as it allows you to search for multiple files at the same time, music and programs. The sin caught up with me faster than light. I noticed that once I logged on to my DSL connection, my computer would keep sending and receiving several megabytes of packets. Making my system virtually slower than a 28.8 connection. I got quite paranoid because I have no idea what it was doing to my computer and what kind of damage has been done. I wanted to remove this piece of c*** right away. I ran "Windows Add or Remove Software" immediately in hope that this will eliminate the problem.

I was dead wrong! Even after I ran the removal software process, my net connection's still **** up. Meanwhile, my Norton Antivirus kept on finding 30+ viruses and Trojans on my system ranging from ABAP.Dosjob, Bloodhound.packed, DSO Exploit to Zyrtec.4300. Pretty much covering every letter from A-Z. I was frightened! After I have removed most of the viruses, I went and checked up on several webboards and downloaded a free trial version of NoAdware and located the process which was the source of the problem. All this went on for 8 hours from the time I got home at 8 PM to 4 AM this morning. This is crazy! I'll never install LimeWire again......It caused me more pain and trouble than other actual viruses. My suggestion to you all is "There are no such thing as free and good stuff....."

Limewire: well... if we're talking tact and diplomacy, then on the basis that it seems not to have done any damage so far you could leave it. On the other hand, it's like leaving your kitchen window open at night. Just because no-one's broken in that way yet doesn't mean no-one will in the future... So personally I wouldn't have it on my pc. If he really likes it though, tact and diplomacy might just say forget about it. You know your brother, I don't.

I'll quote this from another forum I found:


With your sharing problem, there's a couple of potential reasons.

Since it's your file, I'd probably discount their first point and ask if your drive is NTFS. If you don't know, can you find out what size the drive is by going to My Computer? If it's <40GB it could be Fat32. If not it's almost def NTFS.

Another thing to check is that you havn't made the parent folder private, as that would also grey out the option.
