Hi,
I never had wscript.exe running in my taskmanager before. Today I had to open an word document from a friend's pendrive, and as I haven't installed msoffice in my computer, I installed word online extension in torch.
After I opened the word document, I saw this new wscript.exe process is running in the task manager. I felt something fishy about pendrive too, though nothing was detected by avast. All of documents and folders had been saved as shortcuts in the pendrive and their target was cmd.exe in C: drive's system32 folder. As the work was important I had to open the files and they anyhow opened the correct word documents finely.

Now my problem is why is that wscript.exe running? Its folder location is system32, but I still feel something fishy. I manually end the process after my work is done and when I restarted the machine that process started to run again. I end that process again and checked the start up folders only to find out there a vbs file named as 1.vbs which has been created about the time I was using the pendrive or installing word online extension. So I deleted that vbs file too.

Now I doubt my computer might be infected by a virus or key logger even though avast can't detect anything. Can anyone give advice to me, has anyone got this experience before?

What can it do? Completely unknown.
What did it already do? Completely unknown.

The wscript.exe is usually a normal part of Windows - Windows Scripting Host. But it may have been replaced with an infected version with the same name.
The 1.vbs could be anything.

Malware virus scans from multiple vendors, from a bootable CD/DVD.

When I started the machine today morning, vbs file in the start up folder reappeared, so did the wscript process in task manager. So deleting it wasn't helpful. So I decided to disable Windows script host for all machine users by setting the Enabled's value to 0 of Windows script host in regedit.
Am I safe now for two weeks till I format my computer?
