Thanks in advance for the help.

I suspected a virus when my screen would not power down after X amount of time as it always has and my allow remote access was checked which I didnt do. Still my daily ZA scan had found nothing. Checking the logs (in zone alarm) i found repeated suspicious outgoing (to sweden prq, i think) packet which after some research a non-too discrimating ISP site. I blocked it, but wanted to make sure I was clean. Found a odd process dl[1] running and switched my ZA to deep scan, which found the dl[1] to be a HEUR.win32.trojan.generic virus and quarantined it. All i could find on the subject was: it may be a virus. So I came here and did some reading and some scanning. Have run malwarebytes which found some stuff. (clean now), rootappeal (don't know if it found stuff as I didn't understand what it found), ATF Cleaner, SuperAntiSpyware (which found some stuff) (Clean now), and Dr.webcureit (clean).

There is more info available, but my post already reads like a bad report and I didnt want someone falling asleep, so sorry about that.

I've deleted my restore points and reset a new one. I would just like to know if I'm clean. I do my financials on this computer (they have been alerted) but I have trades that need to be done by the end of the month and using the phone to do that is expensive.

THanks again

Any detection that beings with HEUR is generic detection of a file flagged by a scanner which uses a heuristics engine detection for possible new variants of malware before the vendor can get samples and update the program's definitions for detection. Heuristics uses non-specific detection methods to find new or unknown malware which allows the anti-virus to detect and stop if before doing any harm to your system. Heuristic scanning methods vary depending on the vendor. Some claim to allow emulation of the file's activities in a virtual sandbox. Others scan the file more intensively, searching line by line inspecting the code in a file to see if it contains virus-like characteristics. If the number of these characteristics/instructions exceeds a pre-defined threshold, the file is flagged as a possible virus.

The disadvantage to using heuristics is that it is not as reliable as signature-based detection (blacklisting) and can potentially increase the chances that a non-malicious program is flagged as malicious. With heuristics, there is always a potential risk for a "False Positive" when the heuristic analysis flags a file as suspicious or infected that contains no malware.

Please post the results of your MBAM scan for review.

To retrieve the Malwarebytes Anti-Malware scan log information, launch MBAM.
  • Click the Logs Tab at the top.
    • The log will be named by the date of scan in the following format: mbam-log-date(time).txt
      -- If you have previously used MBAM, there may be several logs showing in the list.
  • Click on the log name to highlight it.
  • Go to the bottom and click on Open.
  • The log should automatically open in notepad as a text file.
  • Go to Edit and choose Select all.
  • Go back to Edit and choose Copy or right-click on the highlighted text and choose Copy from there.
  • Come back to this thread, click Add Reply, then right-click and choose Paste.
  • Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Logs are saved to the following locations:
-- In XP: C:\Documents and Settings\<Username>\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs
-- In Vista: C:\Documents and Settings\Users\All Users\Malwarebytes\Malwarebytes' Anti-Malware\Logs


Also let me know how your computer is running now. Are there any more reports/alerts, signs of infection or issues with your browser?

The only thing going on now and not since yesterday is that if I leave/left the computer on a website and came back to it, I would have hit ok to retry to reconnect. I've checked in ZA Extreme security (as there is an option) to make sure that i don't have it set to lock after screensaver so don't know. THat has not happened since yesterday though so I don't know.
Otherwise everything seems to be fine. Its all quite, TOO QUITE. thanks again.

If there are no more problems or signs of infection, 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 backed up, renamed and 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 Posted Image > Run... and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista users can refer to these links: Create a New Restore Point in Vista and Disk Cleanup in Vista.

You're welcome.

Tips to protect yourself against malware and reduce the potential for re-infection:Keep Windows and Internet Explorer current with all critical updates from Microsoft which will patch many of the security holes through which attackers can gain access to your computer. If you're not sure how to do this, see Microsoft Update helps keep your computer current.

Avoid gaming sites, porn sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs (i.e. Limewire, eMule, uTorrent). They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Malicious worms, backdoor Trojans IRCBots, and rootkits spread across P2P file sharing networks, gaming, porn and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans, and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.Keeping Autorun enabled on USB (pen, thumb, jump) and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:Many security experts recommend you disable Autorun asap as a method of prevention. Microsoft recommends doing the same.

...Disabling Autorun functionality can help protect customers from attack vectors that involve the execution of arbitrary code by Autorun when inserting a CD-ROM device, USB device, network shares, or other media containing a file system with an Autorun.inf file...

Microsoft Security Advisory (967940): Update for Windows Autorun
