Didn't install anything, but the number of processes running went up

Hi everyone!

I discovered in my Windows Task Manager about two weeks ago that the lowest number of processes running when idle went up by one. From 49 to 50. By the "lowest" number, I mean the number of processes running when idle. This number (49) had been the same for about a year since I bought my laptop.

The problem is that I didn't install anything two-three weeks ago. Not then, not since then. The number just went up from 49 to 50 for no apparent reason. So, I figured that it was some random application that hadn't been properly shut down and expected it would come back down to 49 when I reboot the laptop -- because I knew it had happened before.

Yesterday, I finally rebooted the machine fully expecting the number of processes running when idle to come back down to 49. NOPE. It's still at 50. What could've happened here?

One possibility is, of course, a virus. After all, about two weeks ago, shortly BEFORE I discovered the change in numbers (from 49 to 50), the MSE caught a virus in my digital camera that had just been connected to my laptop. But, being always careful with these things, I ran the MSE before I opened the digital camera's drive (G:\ or whatever) and the MSE caught the aforementioned virus. And I immediately quick-scanned the digital camera and the laptop with the MSE and the MBAM. No more viruses.

Just for the sake of peace of mind, in the last two weeks, I've run a full scan and multiple sessions of quick scans of both the MSE and the MBAM. Nothing. The laptop is clean.

Back to yesterday, I rebooted the laptop, discovered the lowest number of processes when idle was staying at 50. Upon closely looking at the Processes and Services tabs of the Task Manager, I didn't find any anomaly (or so I think). But it seems that the number when idle is 50 now.

What do you guys think has happened here? Not knowing exactly what's happened to my computer is driving me crazy. Please help.

Thank you,

This shouldn't be a problem. Often, windows starts and stops many different services that require processes to run, as not all of these services are required to run all of the time. Likely, you only noticed this as the infection with virus caused you to look around for damage. My recommendation is to make sure MSE is fully updated, run the scan on "full scan", and not to worry so much. If the virus is removed, you can be sure that it is removed. Update windows in control panel and install all important updates, as there are numerous security patches there that may further strengthen your computer against attack.

PS. You will only need 1 full scan of MSE to catch a virus at any time. 2-100 full scans and 4-60 quick ones will do nothing further for you. It is an active virus scanner, meaning even if the scan isn't on per se, it will still be looking for evidence of viruses. Give the scanner a rest at least until a few weeks have gone by, provided you aren't surfing potentially dangerous websites. If you don't trust a website but feel you must look something up anyway (dangerous), go ahead and do a quick scan. It is a well built antivirus, so give it a little trust

It may be a Windows or some program update added a process to the list. My process numbers range from 41-50 and more. You might look again at some point and it will be 48. Why bother even looking? As my two friends said, nothing to worry or even think about.

If they suddenly increase to 123 I'd be concerned.

I have 61 processes going normally and only 1 startup program. They can be anything from drivers to applications that autorun to windows itself.

Ah, and I looked again and now I have 59. You can't explain that


EDIT* My family computer running vista has 71 processes running... This one I use is a bit slimmer
