Hello all,

Last week during an an online scan with Bitdefender 8, it detected and deleted the following files:

C:\Program Files\HPQ\Default Settings\CpqsetVer.exe
Infected with: Backdoor.Agent.AHJ

C:\Program Files\HPQ\Default Settings\CpqsetVer.exe
Deleted

C:\System Volume Information\_restore{BFAA719B-281F-45B6-9E39-9D4BB578C2A4}\RP2\A0001845.exe
Infected with: Backdoor.Agent.AHJ

C:\System Volume Information\_restore{BFAA719B-281F-45B6-9E39-9D4BB578C2A4}\RP2\A0001845.exe
Deleted


System Info:
OS- XP MCE 2005with SP2 and all latest updates,
Firewall- Online Armor V 2.1.0.85 Free
AV- Avira Antivir Classic
AS- A Squared Anti malware (real time), Superantispyware (on demand), Webroot Spysweeper (on demand, but can set to real time), Spybot S& D, Spyware Blaster

Scans with above AV and AS tools come back clean, and after doing some Google searches it appears this is a false positive result, but if anyone can point me to some additional tools to confirm this, I would be welcome to try them.

Please note- I did post a Hijack This log on the Castle Cops forum, but after additional checking, I have requested that my topic be closed.

Thank you again in advance.

Sincerely,

DM

To get a second opinion.

Go to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file(s) and submit (upload) it for scanning/analysis.
Post back with the results of the file analysis.

Hello quietman7,

Sorry for the delay, but I didn't have a chance to check the forum over the weekend.

I appreciate your suggestion and would have done that scan, but BitDefender detected and deleted the file. So it is no longer on my computer. Based on my other scan results showing clean, should I consider my system clean?

Sincerely,

DM

If thats all that was detected and now your not having any further issues since the removal, then chances are that your system is clean.

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.
