Possible Virus Causing Random Symptoms

Hello. I have been struggling for months with a new computer that I purchase that seems to have been infected with a virus or has had the security compromised. The symptoms are vague and sporadic. The computer will slow down and start using a lot of CPU and/or memory resources. Most of the time when this happens, I will restart the computer. When the computer goes to shut down for the restart, it often briefly shows a screen saying that a program is preventing Windows from shutting down, usually either Explorer or a program titled “G”.

I have run every anti-virus and anti-malware software that I have seen suggested, including in safe mode; however, there is never anything found. I am still pretty convinced that the computer has a security issue.

I have reviewed the steps on your website section titled, “Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help”. I am reluctant to publicly post the logs in fear that there might be personal information in the log or show weaknesses that my computer has for others to attack.

Is there someone that could assist where I can send the log files via email or some other non-public way?

Thank you!

Hello sea_summit and welcome to Bleeping Computer.

My name is Satchfan and I would be glad to help you with your computer problem but I'm afraid that we don’t deal with logs except for in the open forum. I can assure you that the logs we ask for do not contain any information that can be used to harm your computer, (unless your password is same as your username).

Should you decide that you want help please read these guidlines and then supply the logs I ask for:

• please follow all instructions in the order posted
• please continue to review my answers until I tell you your machine appears to be clear. Absence of symptoms does not mean that everything is clear
• all logs/reports, etc. must be posted in Notepad. Please ensure that word wrap is unchecked. In Notepad click Format, uncheck Word wrap if it is checked
• if you don't understand something, please don't hesitate to ask for clarification before proceeding
• the fixes are specific to your problem and should only be used for this issue on this machine.
• please reply within 3 days. If you do not reply within this period I will post a reminder but topics with no reply in 4 days will be closed!

IMPORTANT:

Please DO NOT install/uninstall any programs unless asked to.
Please DO NOT run any scans other than those requested

===================================================

Note: Please follow these instructions in the order given.

===================================================

Download and run AdwCleaner

Download AdwCleaner from here and save it to your desktop.

• run AdwCleaner by clicking on Scan
• when it has finished, leave everything that was found checked, (ticked), then click on Clean
• if it asks to reboot, allow the reboot
• on reboot a log will be produced; please attach the content of the log to your next reply.

===================================================

Download and run Junkware Removal Tool

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/7/8/10, 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.

===================================================

Run Farbar Recovery Scan Tool

Please download Farbar Recovery Scan Tool and save it to your Desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

• right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
• press Scan button
• it will produce a log called Frst.txt in the same directory the tool is run from
• please copy and paste log back here.
• the first time the tool is run it generates another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe). Please also paste that along with the Frst.txt into your reply.

Logs to include with next post:

AdwCleaner log
JRT.txt
Frst.txt
Addition.txt

Thanks
