| Hi all,
|
| My XP (sp2) box has been exposing strange behaviors for a few weeks,
| basically my browsers will work for a few minutes after reboot and then
| can't connect to any website afterwards. but pinging those websites
| just works fine, and DNS (UDP) also works.
|
| I did a simple analysis with ethereal, and found out whenever I was
| connecting to a website (ip: x.y.z.w), a SYN packet was forged to be
| sent to another IP address 140.20.191.20, which is within DOD NIC (I
| remember there is a root DNS server there), and the source ip of the
| SYN packet was x.y.z.w and not mine!
|
| Looks like something malicious was intercepting my traffic and
| regenerating false SYN requests. Interestingly, only web traffic was
| hijacked (TCP port 80). If I login to my company's VPN server and then
| quit, the web traffic becomes normal until I reboot again, I guess it's
| probably that vpn used its own network DLLs to overwrite those
| defaults.
|
| I used MS antispyware and Symantec Antivirus and did not get anything
| out. Anybody here had a similar experience? and any solution?
|
| Thank you!

Download MULTI_AV.EXE from the URL --
http://www.ik-cs.com/programs/virtools/Multi_AV.exe
To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close
Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }
NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your
FireWall to allow it to download the needed AV vendor related files.
C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in Normal Mode.
This way all the components can be downloaded from each AV vendor's web site.
The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.
You can choose to go to each menu item and just download the needed files or you can
download the files and perform a scan in Normal Mode. Once you have downloaded the files
needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key
during boot] and re-run the menu again and choose which scanner you want to run in Safe
Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.
When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help
file. http://www.ik-cs.com/multi-av.htm
