I had a recent virus attack in my system which i solved using avg. But a strange problem is affecting me now. A few minutes after I log on to the internet, I can not get any other process to start. I click on the exe file icons in vain.Even Task manager wont open. Mind you, the system doesn't hang, the existing processes run fine and there doesn't seem to be excessive CPU activity. Initially I thought it was a virus, so I ran Avg scans over and over again, but could not detect a thing. I also tried scanning the system with AdAware and Regrun reanimator, but they don't show any infections either. I found out that the command prompt worked fine , so I installed a command line process viewer to see a list of the running processes when the system stopped responding to exe files. I saw that while that there were no suspicious processes running , the unresponsive files have only one open thread. ex if I click on the taskmgr icon after the system has become unresponsive, the process viewer shows that the taskmgr process has indeed been created but has managed to open only 1 thread. I can not seem to fix the problem. Any help in this regard would be appreciated.
