Hi,
I used your services back in early December when I had the Virtumonde and Vundu viruses. I uploaded Hijack this, Search and Destroy, Ad-Aware, and Comodo programs and was able to remove the virus successfully. I was instructed to update my Java scrpt and download a firewall. I have Comodo.

Anyway, the other day i ran a scan on my Trend Micro AntiVirus and it notified me that it found one item. It said something about a cryp-tap virus in the system volume info folder but was not able to remove the file. I havent had any problems with the computer, except at times it is slower than usual and for some reason I am unable to download microsoft updates via the automatic update. Instead I have to run my Trend Micro software and download each security bulletin individually. This is very monotinous! Another issue I had was that the Comodo firewall would not start b/c of one of the windows updates but I was able to correct that problem.

I will be able to run the Hijackthis log file for you and post later today, but I'm wondering if you could give me some info about this cryp-tap virus, how it got into my system volume folder, hot to remove it, and why i got a virus in the first place with Comodo?

Also, search and destroy was not able to pick up this virus and at times I'm confused as to what to do when search and destroy teatimer and spyblaster send me their alerts. I'm so afraid I will deny a change for soemthing I need! Would you please explain how I can choose wisely and how better to understand Comodo, spyblaster, and search and destroy?

Again, I will post my log file tonight. I just wanted to get some feedback before I begin fixing this issue. Thank you! Actually, how do I run the Hijack this logfile agan? Will you send instructions? :thumbsup:

The infected file identified by your scan is in the System Volume Information Folder (SVI) which is a part of System Restore. This is the feature that allows you to set points in time to roll back your computer to a clean working state. The SIV folder is protected by permissions that only allow the system to have access and is hidden by default unless you have reconfigured Windows to show it.

System Restore will back up the good as well as the bad files so when malware is present on the system it gets included in any restore points as an A00***** file. When you scan your system with anti-virus or anti-malware tools, you may receive an alert or notification that a virus was found in the SVI folder (System Restore points) but the anti-virus software was unable to remove it. Since the System Volume Information folder is a protected directory, most scanning tools cannot access it to disinfect or delete these files. If not removed, they sometimes can reinfect your system if you accidentally use an old restore point.

To remove the file(s) after your system has been cleaned of malware, the easiest thing to do is Create a New Restore Point to enable your computer to "roll-back" to a clean working state and use Disk Cleanup to remove all but the most recent restore point.

Ok, well thank you for getting back to me. So if I run the hijackthis logfile, will you be able to help me remove the file and create a new restore point? I do not want another virus to reinfect!
Also, do you have any advice about my other questions? this is all very helpful.

There is no need for a Hijackthis log to do this.

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.
