Keylogging Virus question

[osucowgirl]

There was a virus that was discovered on my harddrive called w32 randex. It was a keylogging virus which logged everything and put it in a file called ntfsvi.txt

Here is my question: I need to know IF THIS IS POSSIBLE? My husband and I read this file that had stored our keylogging. It started logging on May 30 and ended on July 5. There are things that the keylogger had in it that we did not type. In fact, we were not home during the time and date that was logged. Is there anyway possible that some outside person planted this incriminating information into our keylogger? I am trying to rule out possibilities and trying to locate who and how this could happen. I don't understand the virus and how it works. I do know that it supposedly records all keys stroked on the computer; however, there are things that we typed that were not on the keylog and then there are things on the keylog that could not have possibly been typed on our computer unless someone broke into our house which did not happen. Is there anyway possible that the keylogger could be wrong? I have win2000 and yahoo dsl.

Its possible that you downloaded this program with something quite innocent or indeed installed it with something quite innocent.

Then again it may have exploited a weakness in windows and come to you via that, or a 'friend' my have planted the thing on your machine.

get yourself uptodate with windows patches, a good antivirus program and a decent firewall.

I think maybe someone use your computer, download some emails from his mailbox and it happens that someone sent him a mail with the trojan (keylogger). Without precaution, he run the infected program and the trojan is installed to your computer without his (and your) knowledge. The typings might come from the one who use the computer and bring in the trojan.

Any guess on who can use your computer at that time?
