Virus....Virus...Virus

Thats how my windoze desktop looked when i connected to net when my system was under the attack of viruses. All because of some new viruses with names win32host.exe, smss.exe, lsass.exe etc. Googling said they are called Trojan.systemposer and are capable of sending mass spams, modifying the registry runkey to start them when system is rebooted, spying on keystrokes and exploring the vulnerabilities of other running processes. They seem to do a lot of work than all other processes running in my system. There were around 23 infected files, and with antivirus updates and GNU/Linux i was able to remove some. Still some remain and continue to disturb me. Silly to spend more time and resource to guard the OS than working on it.
