These programs show up in task manager, and seem to alternate between each other for eating up all the processor power, as well as all the RAM.

MsMpEng has to do with OneCare, which is somehow tied to Windows Defender. I'm not sure how, and haven't been able to figure it out. However, I know that OneCare is not installed on this computer. Something needs to be changed or removed on this.

jucheck is a file that I get conflicting reports on. It's either a java updater, or it's some kind of trojan horse virus. I haven't come across enough of a consensus in my research to determine either way. I'm unwilling to remove it until I'm more sure of what the issue could be.

Anytime you come across a suspicious file for which you cannot find any information about, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.

MsMpEng.exe -- 0/36

jucheck.exe -- 1/36
There were 5 versions reported, in old Java folders. There was also one, when I used the search function in a location called "bin" for its pathname. How do I get to that, so I can send it to virustotal?

c:\program files\java\ver1.6.0_01\bin\jucheck.exe || Norman || w32/Smalltroj.FSMP

adproxy.exe -- n/a
Despite being a running process, this exe file seems to have no pathname, let alone an existence on the HD. I couldn't send it to virustotal.

services.exe -- 0/36

When I came back from lunch, I found others eating up a good quarter of my processing power. I put it through virustotal, like the other two. However, I'm having problems getting jotti to come up. I'll try to reconnect to that later.

If they're not virii (with the one exception) what causes them to eat up so much processing power constantly, and at such a high percentage of it?
