Hi all,
Please help me. My sister's pc is very slow and probably still infected with some viruses and/or spyware/malware. Over the weekend, I ran a boot scan with Avast Antivirus which removed 49 viruses (many were of the Trojan variant) but it is still slow and refuses to run Disk Cleanup. She has not been good with installing MS updates when necessary, such as XP SP2. Hard to believe but true. Her 40 GB hard drive has less than 1 GB of available space. So downloading XP SP2 is impossible right now. I did manage to install and run HijackThis, so here is the log of the scan. Thanks in advance for your help.
