In your first post you said the PC was only 3 months old, in the post above that has changed to 5 months. Anyway, I think we should run a few scans to see what might be going wrong.
I suggested removing Kaspersky just to see what happened and to eliminate it as a possible cause.
Please run these four scans and post all six of the logs requested:
SCAN 1
Please download
Farbar Recovery Scan Tool and save it to your desktop. Do not get tempted to download Regclean Pro.
Note: You need to run the version compatibale 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.
- Double-click to run it. When the tool opens click Yes to disclaimer.
- Press Scan button.
- It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
- The first time the tool is run, it makes another log (Addition.txt). Please also copy and paste that into your reply.
SCAN 2
Click on this link to download :
ADWCleaner and save it to your desktop.
NOTE: If using Internet Explorer and you get an alert that stops the program downloading click on
Tools > Smartscreen Filter > Turn off Smartscreen Filter then click on
OK in the box that opens. Then click on the link again.
Close your browser and click on this icon on your desktop:
You will then see the screen below, click on the
Delete button (as indicated), accept any prompts that appear and allow it to reboot the PC. When the PC has rebooted you will be presented with the report, copy & paste it into your next post. If the log does not appear you should find it on your C: drive, using Windows Explorer, as ADWCleaner[S1].
SCAN 3
Download
RogueKiller (by tigzy) and save direct to your Desktop.
On the web page select the 32bit or 64bit button to match the bit rate of your version of Windows.
- Quit all running programs.
- Start RogueKiller.exe by double clicking on the icon.
- Wait until Prescan has finished.
- Ensure all boxes are ticked under "Report" tab.
- Click on Scan.
- Click on Report when complete. Copy/paste the contents of the report and paste into your next reply.
- NOTE: DO NOT attempt to remove anything that the scan detects.
SCAN 4
Please download
RKill
There are three buttons to choose from with different names on, select the first one and save it to your desktop.
- Double-click on the Rkill desktop icon to run the tool.
- If using Vista or Windows 7, right-click on it and Run As Administrator.
- A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
- A log pops up at the end of the run. This log file is located at C:\rkill.log. Please post this in your next reply.
- If you do not see the black box flash on the screen delete the icon from the desktop and go back to the link for the download, select the next button and try to run the tool again, continue to repeat this process using the remaining buttons until the tool runs. You will find further links if you scroll down the page with other names, try them one at a time.
- If the tool does not run from any of the links provided, please let me know.
DO NOT reboot, run
Malwarebytes, let it update and run a
full scan.
Select everything it finds for deletion and post the resulting log. If it finds nothing, post that log instead.
You can download Malwarebytes from here if you do not have it:
