Is this a x86 or x64 machine?
As draceena has already mentioned, most tools do not yet run on x64 systems due to the way they run and protect the files. For instance running HJT on x64 will not enumerate the system sevices and show them as all missing when they are not!
If this is a x86 machine then
most tools will run on windows 7 but there will be very limited support from the authors of dedicated special tools needed for the removal process as testing is still ongoing in this department .
I would try running DDS by sUBs which will create two logs and give us a basic run down of your machine, this tool is non evasive and will not remove any malware, it is for evaluation purposes.
Please download
DDS and save it to your desktop.
- Disable any script blocking protection
- Double click dds.scr to run the tool.
- When done, DDS.txt will open.
- Click Yes at the next prompt for Optional Scan.
- Save both reports to your desktop.
Post both logs back in your next reply
I would also advise a rootkit scan by the use of GMER
Download
GMER Rootkit Scanner from
here or
here.
- Extract the contents of the zipped file to desktop.
- Double click GMER.exe. If asked to allow gmer.sys driver to load, please consent .
- If it gives you a warning about rootkit activity and asks if you want to run scan...click on NO.
Click the image to enlarge it
- In the right panel, you will see several boxes that have been checked. Uncheck the following ...
- Sections
- IAT/EAT
- Drives/Partition other than Systemdrive (typically C:\)
- Show All (don't miss this one)
- Then click the Scan button & wait for it to finish.
- Once done click on the [Save..] button, and in the File name area, type in "Gmer.txt" or it will save as a .log file
- Save it where you can easily find it, such as your desktop and copy and paste this in your next reply
**Caution**
Rootkit scans often produce false positives. Do NOT take any action on any "<--- ROOKIT" entries
