Ok, I recentally have recived a computer from a friend and he sais if I can kill the viral infection on it its mine. So I took the task and have been working on it for two days. Defragging and such. I notice obious viruses in the program files and deleted them. He said it had Norton Anti-Virus but it was an old version and it was expired. Well, I thought just run a scan and remove the viruses by hand. I ran a scan and didn't find a single virus and im thinking this can't be right. It was a full system scan. Sometimes either when I first start up or randomly, it will open random IE windows with random advertisments, but its not the usual viruses like *FREE PORN* Or *FREE GAMES* That I had found on other virally infected computers. I have been able to remove viruses without a full functioning version of an anti-virus program, I usally use ones that just find the virus and remove them by hand.

Anyway...

Aside from the pop-ups when ever I try to open IE it shows an infection by some trojan horse. I am not on the computer right now but ill give you more details when I can access it. But when ever I open IE and it shows the infection it will automatically shut down. I will try the anti viruses recomended in this form section when I have access to it.


Any other recomendations?


~ Thanks :thumbsup:

What OS (Win XP/2000, etc) are you using? Have you performed any anti-spyware scans? Have you tried doing your scans in "Safe Mode"? Are you doing scans while logged into the "Administrator Account" or an "account with administrator privileges"?

You need to start there first. If you don't have any anti-malware programs, see BC's list of Freeware Replacements For Common Commercial Apps. There are several free online anti-virus scans listed which you can perform. I would also recommend that you download and scan with SUPERAntiSpyware Free in "Safe Mode".
Please update the defintions before performing a scan. If you encounter any problems while downloading the updates, manually download them from here and unzip into the program's folder.

Download and scan with Dr.Web CureIt. Follow the instructions here for performing a scan in "Safe Mode".

If Norton is out of date you should remove it. It is useless.
You can try running Norton's uninstaller from the Add/Remove program while in safe mode.
If you have a problem removing Norton, here is a link to Norton's Removal Tool.]
http://service1.symantec.com/SUPPORT/tsgen...005033108162039

Download and Install Super Antispyware free. Reboot into Safe mode and Run SAS. Allow it to quarantine whatever it finds.
http://www.superantispyware.com/

Run the online scan for Bit Defender in normal mode. Allow it to quarantine whatever it finds.
http://www.bitdefender.com/scan8/ie.html

Once Norton is removed you can install one of the free Antivirus programs.

Post back with what the scans found and for further instructions.

Click on the link under "How to Start Windows in Safe Mode"
Do not use msconfig to force a boot into safe mode.

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "OK".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
