Hey, I feel bad when I make these topics, but my family just doesn't grasp the concept of internet security yet and, long story short, theres a bunch of ad junk and who knows what else on there. Symptoms I've seen on here are these sounds in the background that sound like a web page being accessed, then the sound of an ad will play, but nothing happens onscreen. Sometimes I'll hear the firefox popup blocker activate. CPU usage has some spikes, but it generally stays under 10% Computer is running Windows XP 32bit SP3.
Steps I've taken so far:
Ran avast on startup: picked up a bunch of files, some in system32, and moved them all to chest
Ran Malwarebits once: picked up a bunch of stuff that I deleted. Ran another scan, nothing was detected
Ran ccleaner to clear out temp internet folders
I also have some questions. The computer here is running four Windows XP accounts, so say I scan malwarebytes on my mom's account, will it pick up crap on my sister's? Is the malware on my sister's account a threat to the rest of the computer?
Also, the HJT log I included is while logged onto my sister's account. Will that include all the information of stuff starting up across all accounts?
If you need anymore information, let me know. Thank you
