Memory issue?! 8gb dropped down to 3gb!

[KING_OF_SAND]

So I was playing BF3 and noticed that 100% of my ram was being used. I use 2 4gb Corsair Vengeance sticks an I know BF3 does NOT use 8gb. I then looked at CPU-z and it showing both my sticks (8gb) running at 1600mhz, so no problem here. I then checked my BIOS to see if my RAM was working and still everything checks out. I then check task manager and it says I only have 3235mb of TOTAL ram?! That is not even a full stick?

I rebooted with no luck and was working fine before I started playing BF3?! What could of happened? My motherboard is not posting any problems either.

Are you using 64 bit windows?

Of course.

Also I just rebooted again and now 2 of my 4 cores on my 2500k are gone!! WTF!

FIXED IT!! It was a Trojan. I ran my ESET and it found one Trojan and got rid of it. Although there is no information on where it came from but once removing it and restarting my computer worked normally again. I am still investigating on how it got through. I will be testing this Trojan on another computer and dig into what makes this one tick.

I was gonna say something about a virus... Like... That just didn't sound right. There had to be something else controlling your computer.

I figured out what it did too. It changed some values around in the registry so windows would only boot up with 2 cores and 4gb of RAM. I dont know what else it did. Which is why I am going to run this Trojan through its paces on my test computer.

It did not come from an email. It looks as if it may have come from an infected file on a flash drive. Now that I think of it there was a pandemic of viruses planted at my university. Maybe the virus managed to get into my computer through a commonly used executable (Cisco Packet Tracer). It may of come from that.

eset is a decent av but you should get something better than that really, komodo(fw and av) or even msoffice works great

 

[KING_OF_SAND]

It's "Comodo" and Comodo is a joke of an AV, it's just as bad as AVG free is. And are you referring to MS essentials? You have to be kidding!

These are the ones I have tried.

Viper

Comodo

Trend micro

Kaspersky

McAfee

AVG

bit defender

and Norton

and NONE of them did a better job than my ESET. I have been using it on my main computer for 2 years and NEVER got a virus/Trojan. The only reason this got through was because I was ignorant and did not scan my USB which I had ESET always trust. The others on the other hand I have had at least one virus a month with McAfee.

AVG and Viper seemed to be a placebo, Kaspersky I got sick of the terrible UI, bit defender used to much RAM and CPU same with Norton and Trend Micro.

LOL.

Kaspersky is nice man

Yep! Comodo is utter sh**

There have been a few trojans floating around on various sites for about a month now.

The worst one disguises itself as a Windows Media service called "stdrt.exe", and eats memory

I had it

Bypasses most AVs, but easy to get rid of

Manual way to remove STDRT.EXE

1. Restart computer in SafeMode by pressing F8 during starting up.
   
2. Open Task Manager by pressing Ctrl+Alt+Del and end the related processes.
   
3. Delete the following files: C:\WINDOWS\SYSTEM\REGSRV.EXE and C:\WINDOWS\TEMP\MRT2.TMP\STDRT.EXE
   
4. Delete files in C:\Windows\Temp, especially mrt2FC6.tmp and delete those in C:\Windows\IE temp folder.
   
5. Delete/Modify any values added to the registry by the virus, you'd better not to modify registry manually if you know little about it.
   
6. Reboot your computer and check whether the virus is removed.
   

The key point in manual instruction is the registry entries. You should delete those registry entries created by Win32/Parite completely, or you will find that the virus can recreates itself after windows startup.
