Too much RAM usage?

[Anjelous]

Hey guys. I have 8GB memory, usually my system idles with about 18 - 20% usage. In the past few weeks however I've noticed a rather sharp increase to 34% usage at idle. I've closed all the biggest RAM using programs in task manager but it's still to high for my tastes, and never goes below 30% at idle.

Basically I'm looking for a tool or program to hopefully identify where that new 10% of RAM is coming from so I can shut it down? Or do some kind of a system clean? Tips please. Obviously not an urgent problem, but I'm a bit OCD when it comes to my rig.

well i would install some free antivirus such as AVG as high ram usage can be a sign of some malicious program running in the backgroud, you can also download ccleaner which will clean your pc up from registry errors..it also lets you disable startup programs for faster boot

Run Kaspersky Free Virus Removal Tool, It doesn't run like AVG or Avast in the background, but it is one heck of a virus remover, And also run Malwarbytes.

Malwarebytes = http://www.malwarebytes.org/

TDSSKiller = http://support.kaspersky.com/5350 (Rootkit remover)

you don't need to login to download it, Enter your email and name and then check your email for the link. Kaspersky Free Virus Removal Tool mops the floor with AVG

You guys were right on the money. I ran the tests (already had MWB installed, but now using Kaspersky as well) and came up with PUP.Bundler.Installer.OI, a bad little boy indeed:

"PUP.Bundle.Installer.OI is categorized as a horrible Trojan designed by cyber criminals to attack innocent computer uses without any early warning and precaution. Trojans crash down a computer system by using HTTP protocol as a bridge of transaction to install their own executables (components of malware) into your computer. "

I removed it using the AV tools. Running a second round of scans now to see if it's gone, otherwise I'll manually remove it from the registry. Thanks chaps for the great advice
