Laptop was compromised on a bad download. Ran McAfee and they found a Trojan(Generic.dx!grd Filename C:\Windows\sysWOW64\Hydra\Query.exe) and removed it. But I guess it didnt work the first time because i ran another scan and it found the same virus but in a different file(Generic.dx!grd Filename C:\USERS\ELBOWROOM \APPDATA\ROAMING\HYDRA\DEFAULT.EXE). So McAfee quarantined it but I was still suspicious however as there was still a file in my windows folder called bot.exe. :thumbsup: I scanned the file a few times with McAfee antivirus and it found nothing to be concerned about. So I go along on my merry way still a bit wary but thinking the prog was just a shell of its former self as McAfee would have defanged it right??? Yeah right...comp starts acting funny, when typing text it pauses as if something was logging keys, fan goes crazy at times, i'm running peerblock and notice my comps trying connect to other comps on port 80 and other ports even though i am not surfing the web. Just a lot of fishy things so I come here last night and read up on some things and try to diy. I download Malware Bytes and find this...

Then ran GMER twice, found nothing wrong. Ran Malware bytes a few more times found nothing. I do a lot of work on this comp and need it to be secure. So am I clean or we gonna have to rename my comp Amy Winehouse??? Thanks in advance.

Well, nothing showed up on that scan. Lets run another to be sure:


Please download Dr. Web the free version & save it to your desktop. DO NOT perform a scan yet.

Scan with Dr. Web Cureit as follows:
Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
The Express scan will automatically begin.
(This is a short scan of files currently running in memory, boot sectors, and targeted folders).
If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
When complete, click Select All, then choose Cure > Move incurable.
(This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
Now put a check next to Complete scan to scan all local disks and removable media.
In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
In the top menu, click file and choose save report list.
Save the DrWeb.csv report to your desktop.
Exit Dr.Web Cureit when done.
Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

No objects were detected during the express scan. It will not let me run a complete scan. Also there was no log file for the express scan. Is this win??
:thumbsup:

Since I have not received a reply, I will go ahead and assume that my comp is ok :thumbsup:

Thank you very much sir or madam. :flowers:

ONe question however is how to tell if there are still holes in my security? Will my comp continue to be attacked by the person who compromised my machine previously? If so, how to prevent this from happening. TIA

Just make sure that you keep Windows updated by using Windows Update. Also make sure that McAfee stays updated also. And finally, only visit sites that you trust.
