Freezing computer - malware suspected

Hello,

I am facing a serious problem of my computer freezing after each start. Everything started today, after I downloaded several PDF files yesterday from upload/share websites, whereas Kaspersky Internet Security 2012 didn't alert at any time and I checked each file. There is no particular program which causes the crash but the crash takes place always in the same manner: after starting any program, Windows explorer freezes first and after a few seconds the other programs follow. I didn't have the problem when running in the safe mode so I went through all steps of the Malware Removal/Cleaning Procedure in the safe mode and it looks like the computer doesn't freeze anymore but I'm still very concerned because:

• After rebooting the first time after the removal rpcedure, the computer still froze once. Then I uninstalled Java 6 Update 3 since I couldn't do it in the safe mode
• It is quite difficult to interpret the log files but I suspect that the malware was not removed completely because GMER detected some items. How can I remove the them? The log file of GMER as well as other malware removal programs are attached.
• Except GMER none of the programs detected malware (I think) which would be strange.
• After the whole removal procedure, (huge) new files were created in "C:\" (such as "hiberfil.sys" [2 GB], "pagefile.sys" [2.4 GB], "IO.SYS" [empty], "MSDOS.SYS" [empty], ). I also noticed that several hidden "desktop.ini"'s and "%userprofile%" folder appeared on the desktop (I'm sure they weren't there before because hidden folders were visible before the removal procedures as well). May I delete them?

No listed malware was found in the list of installed programs.

Thanks in advance,

AR
