Hi, I am a new member.  It has been suggested to me that my computer might have an infection, although I believe that everything is running alright.   I also run spyware and virus checkers.   I suppose I will have to run some of the cleaning tools.   computercat11O

Hi,  when I asked a question on a Forum, I was told that there might be an infection on my computer.  I really have no problems and everything seems to be running fine.   I feel a bit uneasy to just ignore a potention infection and I was thinking I might run some of the antimalware tools to be safe, but   I feel a bit reluctant, because they sometimes also cause problems.  Computercat11O

it is easy to tell if it runs slow and performs unauthorized commands. Also, missing files and files are now unable to open or perform basic functions. Thats called an infested system :)

Usually when a computer is infected with malware there most likely will be other obvious indications (signs of infection) that something is wrong.

Hi Severac, Malynensi and Bleepin' Janitor,   I do not have any obvious  signs of infection nor does my computer run slow or erratic. I also do not get popups, etc.   Thanks for all the information.  I have now run TDSSKiller (zero problems), Malwarebytes (no problems), RKill which found no problems, but I noticed statement: %Temp% Folder is set to C:\Windows\TEMP, which could be dangerous.   How can I fix this problem????

AdwCleaner only  found SWDUM, which I cleaned, but it belongs to Speedybit, which I noticed too late.  I also used Flush DNS.  I further ran the Malicious Software Tool and Windows Live Essentials.  Should I do anything else?  I regularly delete extra Restore Points and I also use the DiskCleaner as well as CCleaner.  Thanks for all your comments and helpful hints.  Computercat11O

Hello,

 

According to your post, I think your PC is clean and there is no need for extra check.

 

Just to do some junk removal, if any.

 

Please download Junkware Removal Tool to your desktop.

§  Shut down your protection software now to avoid potential conflicts.

§  Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".

§  The tool will open and start scanning your system.

§  Please be patient as this can take a while to complete depending on your system's specifications.

§  On completion, a log (JRT.txt) is saved to your desktop and will automatically open.

§  Post the contents of JRT.txt into your next message.

 

----

 

Empty your temp folders using TFC (Temporary File Cleaner)

§  Please download TFC by Old Timer and save it to your desktop.
alternate download link

§  Save any unsaved work. (TFC will close ALL open programs including your browser!)

§  Double-click on TFC.exe to run it. (If you are using Vista or above, right-click on the file and choose "Run As Administrator".)

§  Click the Start button to begin the cleaning process and let it run uninterrupted to completion.

§  Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway allowing Windows to load normally (not into Safe Mode) to ensure a complete clean.

To repair the path to %TEMP%, run this.

Tweaking.com - Windows Repair All-In-One (Portable)

- Download Windows Repair All-In-One (Portable Version) from here.

- Extract tweaking.com_windows_repair_aio.zip to your Desktop.

- Disable all your antivirus and antimalware software - see how to do that here.
- Right click on QfBzvq1.png and select Run as Administrator (XP users just double click) to start Windows Repair All-In-One.
(Windows Vista/7/8 users: Accept UAC warning if it is enabled.)

- A window will appear. Click Step 2.
2f8o60N.png

- Click the Open Pre-Scan button, then click Start Scan. Wait for Windows Repair to finish scanning.

- Click Repair Environment Variable. When the button changes to "Done!", click the close button to return to Windows Repair. You can close Windows Repair All-In-One at this point.

After repairs are complete you can delete the Windows Repair All-In-One folder.

Regards,
Alex

Hi Severac and Alex,   I have meanwhile run the JRT and also the removal tool for temp. files.  It all went well.   Nothing really showed any infections or anything unusual.  I will try to run the Windows Repair as well, however, I am wondering, whether it would be left to me to find good files, if any are missing.  Would the tool install them or would I have to do it.  Thanks again for all the help.  Computercat

Edit: Repair Environment Variables is just some registry modifications, so no files are involved. You do not need to do anything.

Hi Alex,  the above tweaking tool suggests a pre-scan and also to manually replace files.   I am still not sure, whether I would be able to find good ones.  Thanks for your help. Computercat

If sfc /scannow found corrupt files it cannot replace then you will have to open a new topic in the Windows 7 area with the log from the System File Checker. Someone will be able to help you with the issue.

Hi Alex, thanks for the reply.  I ran sfc /SCANNOW yesterday and it found no integrity violations.  So this part should be o.k.  Computercat

If Repair Environment Variable is successful and sfc /scannow did not report any problems then you should be fine.
