Eventually the virus was gone, but after i installed or run any software from my local drives the virus was re generated. I found that every exe files in my pc was modified by the virus. my anti virus deletes the virus form the windows but i couldn’t repair the exe files. so if any one knows the solution plz help me out!!

I think I have contracted a virus. I am having browser issues. When I try to click on a link from Gmail, Google Reader, Google search, Yahoo search, or a variety of other websites, the browser opens a different, spammy-looking shopping website. It won’t open the right link. I have to copy and paste the address into the address bar to get the page to open. And sometimes that doesn’t work. I suspected that I got a virus, so I Googled "virus removal software." Not a single website that contains virus removal software will open. I get the same error message "Page cannot be displayed" for every anti-virus site I try to visit. This makes me think it is a virus.

Here is something that further complicates the issue. I was thinking that if I can’t download virus removal software, I could purchase some and install it on the computer. But then I remembered that our CD drive isn’t working for some reason. Aaargh! What should I do?

I called the Geek Squad and was told that they recommend an agent come to my house and run a diagnostic on the computer to target the problem. I don’t really want to spend 0 for a guy to come out and tell me I have a virus. I am pretty sure that’s the problem. I don’t have a problem paying to have the virus removed, but how can I do that without paying someone to diagnose it? Any suggestions?

Details: It’s an HP Pavilion laptop that uses Vista.

I have a good anti-virus and registry cleaner and i have no viruses. I have recently installed some more RAM but my computer is still a bit sluggish. It is a fairly new model and i was wondering if you have any tips to speed it up?

This has happened before but it was always related to software. I have put no new software on. I have done a diagnostic and it says everything is ok. This is a Dell Inspiron 9300. My anti virus says no viruses and my spysweeper says no spyware. I did get a message a couple of days ago from my antivirus that said it had quarrantined something that could possibly be a virus. I deleted it and scans since then come up clear. I am also getting a message from my fire wall that says something about ICMP Echo Request (‘Ping’) from (IP addy) and it’s blocking it. Any ideas?
I use avg antivirus, spysweeper, and zone alarm firewall.

Okay, I have Windows Vista 64-bit. Very recently, I started encountering two major .dll errors. The biggest error is the ADVAPI32.dll missing error. I get a message telling me the ADVAPI32.dll file is missing. I have checked in System32 and it is still there, at about 1,038kb.

I’ve seen solutions that involve using a registry cleaner but I can’t open the registry cleaners because that file is ‘missing’. Many of programs like Internet Explorer 32bit, Microsoft Word, MSN Messenger, all of my installed games, registry cleaners, anti-virus programs, and probably more programs will not open because of this.

I also get an error message that says ntdll.dll is missing from the ‘dynamic library’ when I try to open other programs.

How can I fix these .dll errors without using a registry cleaner?

Also, I tried doing a system restore from its farthest restore point. It simply will not work. I need a solution please!
Tried bringing up the command line as suggested in answer# 2.

Came up with
RegSvr32:
"The module ‘ADVAPI32.dll’ was loaded but the entry point DLLRegisterServer was not found.

Make sure that ‘ADVAPI32.dll’ is a valid DLL or OCX file and then try again."
