Leo thank you for the response, I have run various spywares...first i ran spy bot when i scanned it didnt run it stopped half through...then i downloaded adaware...and i ran it , it removed a massive amount of spyware ..but findows still runs when i first start.... i run norton antivirus...i have run a number of online scans at different sites ...one sites was the trendmill site where the scan said that one of the systems files was infected with the backdoor cirebot.A virus...norton is not picking it up it is updated always is im very paranoid about viruses so i do ensure that it is updated and run daily ...I have run the removal tool from symantec site ...it said doesnt have the virus...

i have got to the stage where im thinking I Hate the hackers spywares and viruses and also machines:) i take it reformatting is the only solution for me???

further there are four users on the win xp home what is also interesting is that my daughters account is hidden when i go to "my computer" and the local C drive...when i try to access it from the documents and settings it says access denied...and her account is not passwored...none of us have passwords on our accounts ...

Hi Leo,

Yes, I have a firewall on my router (D-Link DI-604); I've just set it up to block the ports you specified. However, while my router recognizes that I have connected my machine to it via the CAT-5 cable, my machine cannot actually connect to the router and out to the internet. Since I am unable to connect to the internet (the current problem I am trying to fix) and I don't have a CD Burner on my other older machine, I don't really have a way to get an additional virus scanner onto that machine and installed.

Ashraf: certainly could be virus related. Have you followed all the steps in this article?

Daron: Can you connect to anything on the internet? For example are you using that computer to visit this site? If so, I just posted an update to the Sasser article that might apply: http://ask-leo.com/archives/000114.html

Leo,
I'm having some I guess you could call them hiccups with my computer and I think it may have something to do with svchost. When I do a Ctrl Alt Del to check my programs that are running, I have anywhere from 4-10 instances of svchost running at the same time. What does this mean and how do I fix it if it is an error like I believe it is? I did the above steps in the article and it found no viruses or errors anywhere. I can't seem to find anything wrong except that all these svchosts are running. Any assistance is appriciated.

What are the hiccups? As described in this article: http://ask-leo.com/archives/000030.html having multiple svchosts is normal, and not a sign of a problem, in and of itself.

Well its just that my computer is acting odd lately. Mainly when I try to install things it'll either freeze halfway through the install (the progress bar and install shield that is) and when I press cancle my computer crashes or after the install is "complete" the program partially works, the uninstall won't work, and I can't reinstall it any better than the previous attempt. I thought that maybe the svchost was the source of the problem but I suppose not (not much of a computer expert on those things).

Ah. Yes, I wouldn't point at svchost or anything specific just yet. You might try the system file checker, for a start - http://ask-leo.com/archives/000074.html

Alright, I used the system file checker and it said that I had 4 files unsigned (the modified dates were 2 years or more old so I don't think they have anything to do with my current problems).
