Over the past week or so I've noticed that my laptop (running Windows XP) has been running extremely slow. Upon review of active processes in task manager, I notice several occurrences of explorer.exe, chrome.exe, iexplore.exe, svhchost.exe, dllhost.exe, etc., even when I don't have a browser open. Our 3rd party IT support professionals have attempted to remove the viruses/malware that seem to be affecting my machine. They have run rskill, combofix and Malwarebytes on consecutive days.
The system seems to run better for a few hours and then, without warning, the system will come to a near stand-still. I keep having websites pop-up on my screen even when I don’t have a browser open.
The only way for me to actually get back to the application(s) that I’m working on (Word, Excel, Acad, Adobe, Outlook, etc.) is to go to the task manager and select “Switch To” making sure the application that I desire is highlighted. There is no way to minimize the ads when they pop-up. They simply freeze my screen. This becomes necessary in order for me to save anything that I may be working on when the ads pop-up. A system re-boot is my only option after saving my files.
Our IT support professionals want to re-format my hard drive which I prefer not to do for obvious reasons.
I realize that my machine and operating system (XP) are dated but that shouldn’t change the fact that whatever spyware or anti-virus software that is being used to monitor my system isn’t doing a sufficient job. I don't want to spend $1k on a new system and continue to have these problems.
Is there any other malware/spyware software that can be used to find what’s ailing my system?
