Windows 7: Very slow pc, multiple processes

The basics of process and file locking in Windows... If a file is opened by a process, or the file starts the process - that said file is locked by the system, you can't do anything to it. Now, every applications out there that runs on Windows have the same behavior, be it a "legitimate" applications like Winamp, Microsoft Word, iTunes, Windows Media Player, OR an "illegal" application that harms your computer like virus or malware. With that basics covered, there's another behavior in Windows that let's one process communicates with another process, it's called InterProcess Communication (IPC). By leveraging this, a virus or malware can hinder an Antivirus or Antimalware easily, even at times can crash the said AV/AM. Now, if you really want to clean up your system, you can't have the OS running, because of the file locking behavior, you can't clean a running virus, the process locks the files... Some virus even have the ability to re-copy it's "body" if the "body" is deleted by some AV/AM.

Installing and scanning virus/malware in an infected computer is moot to some degree, you won't get a 100% clean system, because you'll never know if there's no other virus running which hinders your scan, or if your AV is not compromised by the said virus/malware. My best suggestion still stands, get the AVG Live CD (or any other AV live CD) a try, or plug your disk to another clean system and scan from there, at least it will catch something, hopefully it will catch most of your pesky virus/malware... Good luck.

I know it is for advanced user but its worth to try before you plan to reformat your pc

feel free to ask
I want to wait with formatting till I finnish my year, I need lots of programs to hand in Drawings and stuff ( In uni have exams right now), I'm trying every other option possible to scan and delete as much stuff As I can, Every scanner seems to find something and deletes it, al of them were trojans ( See ESET results for exmp in previous post),

When the problem is not solved i will reformat in summer.

Altough it seems all the scanning is helping, now CPU runs pretty normal Stays at 20 % and peeks from time to time, which is normal, RAM running at 1 GB oF 4, most problems seems solved, now its just finding everything (like the backdoor tojan) and deleting them so nothing new can infect my pc, ESET seems a good program but I look around the forums for protection programs best fitted with Win7 64 bit.

If I need a reformat I'll contact via forums

My computer has gotten molasses-slow over the past 6-12 months with no major new programs. Could it have something to do with the 71 processes that Task Manager reports when the computer is freshly started, with no programs opened? They use about 1 Gb of RAM - is that high? High or not, the...
