I got a call from a frind to help remove a virus problem they were haveing. I ran Malware bytes and avast and it cleaned up the major problems the viruse was causing. I was to run spybot but it is unable to connect to the server to update and I cannot register avast because I cannot connect to the website. I can go to google... micrsoft... ect but not the avast website, norton, avg, or any other website that has to do with antivirus. I copied the installers for avast and malwarebytes from a flashdrive. Any ideas on how I can get it to where I can connect to antivirus websites?? The main exe i deleted was bill103.exe... once it was gone... the computer was usable again.

Good start, — initial cleanup with portable scanners is the right first move. When general browsing works but antivirus vendors are blocked, the usual causes are local name/proxy redirection (hosts file or WinHTTP proxy), a corrupted network stack or LSP, or persistence entries that keep the redirect active. Before editing anything, make a full image or at least a restore point so changes can be undone.

Quick, non‑destructive checks to try (run an elevated command prompt and back up files first):

ipconfig /flushdns
netsh winsock reset
netsh int ip reset
netsh winhttp show proxy
netsh winhttp reset proxy

Also open the hosts file at C:\Windows\System32\drivers\etc\hosts and remove any lines forcing antivirus domains to loopback or other IPs. Check browser/IE LAN proxy settings and disable any proxy. Reboot after the resets and try the vendor sites again.

If problems persist, boot into Safe Mode with Networking and test connectivity there. Use a clean PC to download rescue ISOs or portable scanners, transfer them on a scanned USB stick, then run offline scans. Use Autoruns (Sysinternals) to inspect Run keys, services and scheduled tasks rather than hand‑editing registry keys; that gives a fuller view of persistence. Check the router’s DNS settings (some malware hijacks router DNS); if suspicious, change DNS to a trusted resolver and consider a router factory reset and firmware update.

Good points from others: was right to look for persistence, and ’s suggestion to use Microsoft cleanup tools can help. Reinstalling AV (as suggested) is sensible only after you confirm network redirection is gone. If the infection resists cleanup or critical system files are altered, image the drive and consider reinstalling Windows as a last resort.

Its a small file conflict i think. PLease uninstall all your anti-virus applications, after disblin them. Then first u visit websites and check is the problem still exists. then install avast and check again. then u can install any other anti virus applications..................


i hope it cleared your problems....... tk care

bill103.exe is a malware. It is a koobface worm variant. You can search about it on the net. While maybe you can try below explanation to solve the computer that won't connect to any anti-virus software.

Click Start -> Run -> type regedit and hit enter.
Registry editor opens.
Navigate to the following keys by expanding the + at left of each key at left:
HKEY_LOCAL_MACHINE
SOFTWARE
Microsoft
Windows
CurrentVersion
Run

In right part of window, right click to sysfbtray and select Delete. Confirm it. Close regedit.
Reboot computer.

Try to download a decent AV and/or update your current AV.

Hope it helps solve your friend's issue.
