I just returned from holidays and before I left, I thought I had rid my system of virus dialer.x.x.

I just went on line and updated AVG (free edition), ad-aware and spy bot. In this short period of time, my system was reinfected.

I have searched my registry and used windows explorer and found some suspicous entries which I have deleted; and yet the virus returns every time I access the web (within 15 minutes). Obviously there is something in my system that is calling home, but I cannot find it and I have already wasted countless hours trying to do so.

I do not wish to repartion and format my HDD; my internet access is POTS and updating all my software will take 8 hrs (max. file tranfer rate 2.6 KBytes/sec.)

System specs: XP Home,adaware,browserhijacker blaster, spybot, hijackthis, noadware, stinger, cwshredder, dsostop2. I also previosly tried trial versions of other related software.

System restore is not in use and I have found an index.dat file that I cannot remove, Also, I am unable to run AVG in safe mode.

Any assistance you may be able to render will be greatly appreciated by this ole farmer.

Thank you
Greg

ps: I have also used online virus checkers etc.

Hello Greg,
AVG is pretty good for a free anti virus program but, it doesn't have what it takes to combat some of the more agressive viruses. Free will only get you so far. Invest in Norton or McAffe anti virus for more complete protection.
Dialer will usually put a dialerxxx.exe, or some variant of the name, in the root of C: or the root of the Windows directory. Boot the computer in Safe mode and do a search for "dialer", without the quotation marks. Windows has a dialer file that is legit, dialer.exe. To verify the authenticity of any dialers the search uncovers for you, right click on each executable dialer and sellect "Properties". Under "Version" you will find if this is a Microsoft file or an imposter. Rename the file extension, of any non Microsoft dialers to bad, such as dialerxxx.bad. Next, run msconfig and uncheck any box that refers to dialer. Now go to the Control Panel>Internet Options and delete your Temporary Internet Files and clear the History. While under the Internet Options, click on the Programs tab and reset your programs to Default, including your Home page. Now you can open Internet Explorer and click on Favorites and remove anything from your Favorites list that you do not want there. Check this list closely.
Check your host file for redirects. Do a search on host and double click the file " hosts " without a file extention at the end of it. Make sure that the listing is -
127.0.0.1 localhost
remove any other entries.
OK, boot back into Normal mode, whatever that is suppose to infer, and go to :
http://securityresponse.symantec.com/
and click on Check for security risks. Do an online virus scan of your computer and follow Symantec's removal instructions for any viruses the scan may find.

thank you for your suggestions. I have previously done everything suggested, except search for host. I found the file that you mentioned, but am unable to open it. AVG finds and quarantines dialer.8.u and dialer.9.a, but my system seems to have something well hidden that is leaving it vulnerable to attack. I must admit that dialer.8.u is a bit of a pig to get rid of. Thanks again.

regards
Greg

...... from previous post
Once you are certain that your system is virus free, remove AVG and install a fresh copy of either Norton or McAfee. Get all the updates available and then get all of the Windows Critical Updates. Considering your download speed(?), you will be better off ordering the update disk from Microsoft. A small shipping charge is the only fee.

I hope this helps you.

Thank you for your suggestion. I apologize for not mentioning that I installed spywareblaster and bhblaster already.

If you dont wanna spend money. Get stinger.exe by mscaffee. It's a free download and will remove any new viruses. Once that is gone. updte and run avg you should then be fine.

by lmon

Also, update windows with any service packs or updates that way you dont keep getting the virus.

Thank you for your suggestion. I already use Stinger, along with a whole lot of other programs.

hummm if you use an always on DSL connection and you don't have a router, but use Windows XP Home's built in firewall AND have more than one computer connecting to the internet, I suggest you get one. Routers have the ability to block at the WAN port ICMP ping, IGMP multicast, PPTP, L2TP along with providing NAT to LAN computers. Think of a router as the first layer, and the firewall on the LAN computer as the second layer, the spybot programs as a 3rd layer, the AV program the 4th layer, and machine security like requiring passwords, and machine security settings as the 5th layer of protection. The more layers they have to go through the harder it is to get in.

Some bug/virus/trojan writers are now using the IGMP broadcast to get their programs out. So if you leave your computer running [sometimes even when it's not running it can happen] while away on vacation thinking you've got a firewall and AV and your safe, that might not be the case.
taken from IGMP article on
IGMP Overview http://www.zyxel.com/support/supportnote/ves1012/app/igmpsnoop.htm

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient) or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group of hosts on the network. If your computer firewall doesn't block IGMP broadcast traffic, your vunderable. multicast traffic is treated in the same manner as broadcast traffic, that is , it is forwarded to all ports

Thank you for your thoughts. I access the Internet through a dial up service and never leave my pc while connected.

Notepad will open the host file.

Are you saying that you do not know which application will open the host file or will it not open with notepad?

What is your OS?

Let me know with a comment, please. I feel rejected enough already. *smile*

Hello:

The host file icon is one which indicates that my system doesn't have the program to open it. I am offered the option to search online for the program, which I have done, but there is no response. Also, this may be coincidental, but notepad.exe is no longer accesible. My OS is XP Home.(always updated)

I think the answer lies in finding my system vulnerability, wherever that may be. Normally, I would have deleted my HDD, but view this as a learning experience. I have become comfortable with editing my registry and contrary to what the text books warn of, the sky didn't fall. As I have previously mentioned dialer.8.u is like the inlaws, really tough to get rid of!

The only bright spot is the fact that my system is only infected once every 24 hours and it is easy to recognize when it enters my system. I have tried browsing different web sites to see if that made a difference, but no leads there.

Greg

Thank you for your suggestions! I have already spent alot of time on this problem and I,ve already done numerous online virus and spyware scans. I also now have more software on my system than you can shake 2 sticks at. My system is cleaned and all traces of the virus removed, but within minutes of connecting to the internet, my system becomes reinfected.

I know you don't want to format your PC and have to reinstall all of your system updates, etc., however....with the time you have spent on this problem, you could have done that a couple of times over!

I suggest you FDISK and format, reinstall your operating system and then, take your CPU to a friends house who has a broadband connection. Plug into their network and download all of the patches, etc. within a few minutes.

I did this for a friend of mine, and not only does the system start fresh and clean, but we got to have a couple of drinks while the process completed!

Don't forget to backup any necessary documents, folders, settings, etc., prior to formatting.

I just think this is something that will keep getting worse before it gets better! ;)

Good luck!

Thank you for your suggestion. You are right in that the problem is getting worse, but I am viewing this as a learning experience. I aspire to be a good comp. repair tech. and do enjoy trouble shooting! This is the reason I haven't done as you have suggested a long time ago.

Install Zone Alarm (it's free and good) and try to block unknown or suspicious outbound traffic. Some malware uses innocent sounding names close to Windows services and apps. Chase name down using search function and look for publisher info under properties as described in prior response.

XP firewall is for incoming only and not very effective.

If the critter can't call home, you may be able to remove it once and for all.

I have used Zone Alarm Pro and had 2 problems with it. it. Both were related to how I access the web. I am using dial up and firstly, it made an already sloooooow conection into something totally unacceptable and secondly, it would periodically freeze my OS (XP Home). Support at Zone Alarm said it was caused by my not being able to download the program properly at my internet connection speed and cheerfully refunded the $.

Addendum to above.

When you run Ad-Aware select custom scanning options and enable all.

Apparently, AVG will not run in safe mode. Don't know why, but it doesn't.

Thankyou for your suggestion, but I have already tried that.

Just make sure that u always update your scanner's reference file just like updating your virus definition.

When using trial versions of softwares keep in mind that it is limited in clout as the full version, (ad-watch in adaware is not loaded in trial version) which is sort of like Vshield.

Plus browsing the internet makes you very susceptible to this attack specially downloading files.

This may sound tasky but u always have to update and scan repeatedly

Thankyou for your suggestion. I always keep all of my software fully updated and use it on a daily basis.

Have you checked Run and RunOnce in the registry? Startup? And might as well check Autoexec.nt, config.nt , win.ini, and system.ini.

Thank you for your suggestions. As the saying goes, been there, done that. I found nothing suspicious in these files.

Rural,

Try this. go to Hauriusa.net and download the trial version of Hauri Anti Virus. Make sure to update the virus defs.

Then...disable your system restore
scan with hauri and delete all files that it catches, clean your cache, temp files, history folder, cookies folder, recycle bin, reboot, then re-enable system restore.

Good Luck~!!

Thank you for the suggestion. I just finished scanning my system with the virus checker you recommended and it didn't help any. AVG is still the only one that finds the virus.

As for the rest, I always do those things everytime I go offline.

Greg
