Browser Message: Blocked because of virus

Greetings,
I'm getting the message, "Blocked because of virus. A virus was detected, originating from your system. Please contact the system administrator." When it happens, it appears on every browser that I'm using IE, Firefox, Chrome, or Safari.

When it happens I cannot access the Internet, but I can access a local Intranet. I can usually get the browsers to start working again by running the anti-virus program, Symantec Endpoint Protection. However, it has been happening so long that I've decided to try majorgeeks.com's suggestions.

I've been through all of the steps int the "READ ME FIRST.Malware Removal Guide" for Windows XP System. I've attached the log and zip files for the five programs.

Please allow me to thank you ahead of time for your assistance. Right now, I can get to the Internet, but that annoying little screen will appear again soon.

Thanks,
Steven McCrary

 

It looks like I have to buy the product to delete these threats? Correct?

 

Well, Hitman is asking for a Product Key to delete the threats. I pushed "I do not have a key" and it takes me to the site to purchase a key. So I closed it and tried again. Whereupon, Hitman would download an update and then close. Try again, same thing...every time...no progress possible. So, I downloaded it again from the Web, and re-installed it.

Scanned the computer again with HitmanPro 3.7.3-Build 192. Again, Hitman is asking for a Product Key.

Now what?

 

Not sure about having Hitman on here for 30 days, oh well.

Downloaded JRT.
Due to corporate policy, I cannot shut down Symantec, so I ran it in safe mode as administrator and at my login.
.txt files attached.

 

Thanks for all your help so far, and for staying interested in the problem!!

Things were good until about noon today. Then, I got the message again.

:-(

Now what?

 

Here ya' go.
