Windows 7: My computer is very slow at startup and Window Explorer keeps crashing

My computer is very slow at startup and Window Explorer keeps crashing

Hello,my name is Will (William). I'm very new here(joined when this problem started occuring). I have a 1 year old computer with a serious issue on it. Since a windows update 5-6 days ago my computer is extremely slow in normal mode. First it just crashed all the time. I couldn't shut it down the normal way so I had to press the power button. Since I'm a quite impatient person I restarted it several times resulting in the same thing, Windows crashing. Realising that I had other things to do I left my computer for a while.

A few hours later I tried again. This time it worked. The computer was slower than usual at the start and I had to leave it working a while before a I could use it. But right after that I ran a scan. In both Microsoft Security Essentials and avast Antivirus. Microsoft Security Essentials found a virus. I think it was located somwhere in Win32. It deleted it automatically.

After that I was away for a few days but when I came back home it was even slower. Now it can't even load the desktop normally. Sometimes it shows all the icons, but nothing will open and windows crashes when I'm trying. Soetimes the icons doesn't load properly.
Weirdly enough safe mode works perfectly fine. I'm writing this thread in safe mode with network. I have opened my computer and blown away dust and such thinking that might cause some minor problems. Nothing happened.

Now I'm browsing for solutions to the problem. sfc /verifyonly finds nothing and neither does sfc /scannow. I've also tried downloading ShellExView and disabled non-Microsoft content to no use.

I do have the SF Diagnostic Files for my computer, added it to attachments.

You should not be running two AV"s. Uninstall Avast now.

Then work through these steps to Clean Up Factory Bloatware.

If that isn't sufficient to improve performance and/or find solutions then follow these steps to Optimize Windows 7 - Windows 7 Forums

Let us know how it goes or if you have any questions.
