Low Memory Error Caused by Virus

tening · 28 Jun 2023

Recently I install several softwares downloaded from the internet. My anti virus detect virus when I install these softwares. I turn off the anti virus and let these softwares be installed in my laptop. Then the problem caused by the virus is occure such as written below:

1. When I open many programs (or multitask), the screen of my laptop is turned off automatically (the color is black). However, the engine is still running. So, there are not much I can do except to force restart my laptop by pressing the power button for 10-15 seconds. Before this error occure, I can do multitask in my laptop without any problem even playing a heavy PC games such as Football Manager 2023.

2. It appear about 3-4 windows as blue color and the position of the progam is cascading and close automatically. The process is so fast so that I can not read what program this is. But I believe my eye saw the title of this program is "...powershell".

3. I also experience a "Runtime Error". Everytime this error message is appears and I clicked OK option, the current running program is closed automatically.

4. I do full scan all of the drives on my laptop by anti virus software. The anti virus got 10 detected viruses, and then I clean and delete all of these viruses. However, the low memory error still occure.

These are the screenshot of the error messages I meant:

My Operating System is Windows 10 Pro (64-bit) and the version is 22H2.

My laptop is Samsung Series 5 Ultra with Inter Core i5-3317U, 1.70 GHz and 8 GB of RAM.

Can someone tell me please what should I do to bring back my laptop to normal?

Please help me

Thank you

The lesson learned here is to believe your AV software when it tells you that you are downloading a virus and not to install it.
Try a System Restore to a time before this install.
Also, do a scan with ADWCleaner, Follow this up with a scan using Malwarebytes. Remove or Quarantine anything they find.

What is System Restore and how do I find it in my Win 10?

System restore will not remove most virus ! I would like you to run these 2 programs & we can see if they find anything, if not we can try other programs !!
Malwarebytes AdwCleaner >>> Download AdwCleaner

Please download AdwCleaner and save it to your Desktop
* Close all open programs and browsers
* Right click on the icon and select Run as administrator
* Click Scan now
* Allow the program to Quarantine what it finds except for Pre-installed applications if you would like to keep those or other entries you would like to keep
* When completed click View Scan Log File
* Copy and paste the contents in your reply
* Click Skip Basic Repair if it appears then close the program

=================================
AdwCleaner will remove "PUP's" which are not viruses ! However, PUPs can compromise your privacy and security and cause unwanted behavior on your device.

This is the Powershell error I meant about:

Low Memory Error Caused by Virus-powershell_error.png

Also I remember the type/kind of viruses detected by my Anti Virus software are worm and trojan.

- - - Updated - - -

These are the Log files of my computer scanned by using the AdwCleaner.

It found 4 files and I already quarantine them.

Should I delete all of these files detected by AdwClener software in its Quarantine folder?

What should I do next?

Should I do the System Restore?

@tening, yes quarantine/delete them !
Please download & run this program, post the results back !
RougeKiller >>> Download RogueKiller

No do not do a system restore !

I saw your AdwCleaner logs...
I just want to point out that it removed two of your VPN extensions in Google Chrome;
• Touch VPN
• VeePN

If you still use VPNs, then you can re-install them. Those two extensions aren't malicious. Dunno why AdwCleaner wanted to remove them...

This is the scan result using Malwarebytes Premium Trial 4.5.3.1.
I already quarantine all detected files infected by virus.
But I didn't know where is the location of these quarantined files.
What should I do?

Also this is the scan result using RogueKiller Anti-Malware (Free) 15.11.0.0 64 bits.

@tening, your Malwarebytes log show you did not quarantine the bad files, and they do need to be removed !! There is a lot of bad files there !! Then re-post a new MBW log !!
