As stated by the captain, if it's a standard user account it's normal. The second exe from above in the screenshot is part of a banking software normally .
banking??? what do you mean? Bank? I'm afraid of it is not safe,that i told you before above-mentioned
Alipay - online banking software popular in China and Taiwan according to Google. You also said you downloaded windows from a Taiwan website, so maybe it was pre-installed. It is always best to start with clean / MSDN iso files.
what about csrss.exe and winlogon.exe. Both of them have existed before I were installing the banking software . Is it safe?
I agree with s1ave77. Usually Loaders and MTK are safe to use. Cracked (premodified versions of windows) tend to be somewhat questionable as you have little to no idea what modifications were made to critical Windows components. Personally, I'd use an official, retail version of the Windows install media. Then later use Microsoft toolkit to deploy KMS. This way it's a guaranteed safe installation.
You may also want to note that Microsoft Toolkit only works with Win 7 Professional or Enterprise editions , and Enterprise is not available as a retail product.
Do yourself a favor OP, get your .iso from any of the available sources on this forum. The version of W7 you have is questionable, at best. If any of your other software is cracked or you used a keygen, your install is compromised. Using a crack or keygen is tantamount to giving a thief the keys to your front door.
This forum too many Windows 7 ... I don't know which one is available.. (I don't want to make the thief to steal my things from my desktop.)
What you have asked about so far are normal processes that run on all Windows systems. Based on what you have posted so far, there is no clear evidence that you have been infected by a virus. There is also no clear evidence that you have not. Find and use a decent anti-malware program before trying anything else. If you do need to reinstall, the links posted by Wazoo are a good place to find a clean iso.
