Hello!

 

My computer is experiencing some issues.  It's not allowing me to connect to the Internet; I've tried different browsers, restarted my Internet modem, restarted my computer itself, re-connected to the network.  Nothing works, and it just endlessly loads when connecting to the Internet.  It's for this reason that I believe I'm infected. 

 

I do have a flash drive and another computer to use, so I can transfer any needed diagnostic tools.  Any help would be greatly appreciated!

 

Thanks in advance!

 

EDIT:  Now Firefox won't even load at all.  It just freezes when I attempt to use it.

1.  Firefox issue ("Now Firefox won't even load at all"):
1.1.  Sometimes FF won't clear out of memory.
1.2.  Bring up Task Manager and look for all firefox.exe (there may be multiple copies).
1.3.  Terminate all firefox.exe that's there.
1.4.  On start up of FF the next time, you may get a notice about restarting the previous session, tell it no.

2.  Your internet issue.
2.1.  Call your ISP and have them "rebuild" your connection (its a simple step for them).


Best of luck.

Thank you for responding so quickly!

 

Is it normal for only one computer on the network to need this "rebuilding" process?  I'm typing this from a laptop that's successfully connected to the same network that my other computer is having trouble connecting to.

What is the OS of the computer you think is infected and can you give it a Ethernet connection to the internet.

Thraino, are you connecting to the internet directly from your modem or are you going through a router?

 

One thing I've seen a lot of times, especially if it's a HT-1100 or similar model of modem is that those modems and some routers often have conflicting IP addresses. 

 

If this is the case you can log into your router and on its lan settings page you can change the IP address from (for example) 192.168.0.1 to 192.168.1.1 and see if that would solve your problem!

 

Let us know how it goes though please :thumbup2:

On the internet connection issue, also try:

 

1.  Open Command Prompt at the elevated (Admin) level.

2.  At the prompt, enter the command (no quotes): "netsh winsock reset"

3.  At the prompt, enter the command (no quotes): "netsh int ip reset c:\resetlog.txt"
4.  Reboot

 

Best of luck.

I actually called the internet service provider as you instructed, and she had me do this!

 

And, what do you know, it's back to normal!  Thank you all so much for the quick input.  I feel slightly silly for thinking this was a malware issue.  I guess I'm just too paranoid for my own good after getting infected a few years ago.

 

Thanks again!

Some malware can affect connections.  I got clobbered in 1995 and have taken an aggressive approach to security since then.  Knock on wood, no viruses, malware, hacks, etc since then.  Trust me, you'll have people that will tell you that being "paranoid", and they'll mock you.

In my case, consider 18.5-19.0 years virus, malware, hack free, a healthy dose of paranoia has paid off.  Every person that mocked me, I got the last laugh :hysterical:, when they got infected, etc.  Some might say me laughing at them is wrong.  But, they were wrong calling me paranoid and mocking me!  I took an aggressive approach after the 1995 situation, and have been clean ever since.  After the ones that mocked me got infected, they asked for help, and I'd tell them: :censored:

Have a great day!
