I have inherited a computer which is acting oddly, and I don't know if it is a problem with Windows Xp or Malware.
When I try to install new software, such as Ewido or PC-Cillin, it starts installing and then just cuts out, i.e. the installation stop and the installation window disappears before the instalation is complete. For some software, like Autoruns, I was able to install it, but when I run it, it does a scan and then disappears before I can read the results. When I connect to the internet (dialup), it starts loading whatever page I am connecting to, but soon the Internet Explorer just disappears and I have toopen it again, which means I can't even to a Trend-Micro Housecall!!!
Is this an OS problem or Malware? I have put a posting on the malware forum in case, but I can't even get Hijackthis to work anyway.
Any suggestions as to how I can get far enough with installations to even check for malware??
