When I started my computer this morning I noticed it was painfully slow I then noticed that in task manager processes there were 2 instances of Explorer.exe running; one with a fairly low amount of memory used the other with roughly 10 times more than any other.

I looked at my Resource Monitor and there were over a hundred instances of Explorer.exe accessing the Internet.

I scanned the entire computer with AVG and Avast, which lead to no results.

The memory usage has dropped significantly, however there are still two instances of it running in processes.

  • Have you scanned it for malware? Check out How can I remove malicious spyware, malware, viruses or rootkits from my PC?. – CharlieRB Dec 24 '14 at 15:50
  • Are you sure it was "Explorer.exe" processes (Windows Explorer) accessing the Internet, or was it "IExplorer.exe" (Internet Explorer) processes? In the Resource Monitor, where were you seeing these exactly? And did they all have the same Process ID (PID)? Is it still doing it consistently? Does it do it while booted into Safe Mode? – Ƭᴇcʜιᴇ007 Dec 24 '14 at 16:05
  • if you have activated the option to run the shell in a separate process, you'll see 2 explorer.exe instances. – magicandre1981 Dec 25 '14 at 7:36
  • I have done multiple full system scans with AVG, AVAST and Kapersky's 'TDSSKILLER' these reduced the amount of memory used by explorer.exe however it seems this happens without any scans over time as since starting my computer the data used has been reduced by 3/4 by explorer.exe however the number of instances of explorer.exe accessing the internet in the TCP connections section remained the same. – sam1234 Dec 26 '14 at 14:57
