Hi, everyone, i am zhaul and in need of help, please forgive my english, not my native language. (but close) hehehe.

I am posting this out of one question what is happening to my laptop is normal?

I am going crazy over this. I recently had a terrible problem with my computer, that ended in the lose of all my info. In the end the technician had to reformat and install everything, due to many viruses and malware. since then I haven't used Limewire or Ares, however, I have downloaded files from Rapidshare, Megaupload and others. Who claim to have clean files.
AW,

MY lap is a 1.2 ghz pent III 758 mb of ram 40Gb HD with two partitions C: and D:

I have run all I got:

Kapersky. nothing detected
Highjack this ?? dunno computer language
Nod 32 nothing detected
AVG antivirus which detected 2 adwares: Generic and Titanshieldspyware
those where remove from 30 detections but they were not reported as threats. (I am afraid I have cancelled one of my programs)
CCleaner, small log file.

Non of the above detected those invisible files that the defrag read:

Disk Space Reporter reads on disk space used

C: 4.352.624.250
D: 628.588.833

Windows properties reads on disk space used:

C: 5.019.873.280
D: 959.467.520

Is this difference normal?

And I did a defrag on dsk D:

and it read:

Moving file A0017994.exe
moving file A0017995.exe

Both are invisible to explorer, or other programs, except to defrag.

I have formatted dsk D: and after doing it the explorer gives about 69.000.000 bytes used disk space
I have to add that I have done the formatting twice, and those invisible files come back.
The disk space reads are what I have just now.

Please advice, dunno if I have an invisible problem that can't be detected.

There is another little problem I detected which dunno if it is related
a few days ago my svchost has been jumping from 0 to 45 and sometimes to 99 for few seconds making the connection to a link sometimes a long wait. After I killed it in the task manager firefox runs smoothly. I checked with process explorer
and found out that this svchost manages dnsrslvr.dll only. I went to check the properties of it, and checked internet for possible threats and seems like has very low risk, the ver. is 5.1.2600.2180 And everything points out that it is ok. I thought about changing it for the most recent ver 6.0.0000.0001 I think don't remember or for a later, but I am afraid to make a terrible mistake.

There is no reason to believe I have maleware, but I do not know. I hope I didn't break the rules. I considered that this post should go to maleware removal.

Thanks in advance

file A0017994.exe
file A0017995.exe
Both suggest a trojan infection. I would post here to be sure:
