Hi, I will give you a bit of background first. The computer was bought second hand for my mother in law (no operating disks). Only 256ram, but from blogs this should be ok. It is only used for internet browsing, word processing and digital photo storage (not many about 100). She said she was having problems with microsoft updates. When I had a look at it, it didn't have sevice pack 2, and that was stopping the updates. I got hold of sp2 and installed and then downloaded 82 updates. I noticed it was running very slow at startup, shut down, and both on line and when not connected to the internet. She confirmed that it had been running slow. I tried Disk Cleanup, remove cookies, defrag, and stopped most programs loading at start-up, all with no change. I then started to go through the viruses/spyware/malware, preliminary removal instructions. I followed as much as I could; step 11 - no installed rootkits spet 13 - could not start safe mode - used f8 went to the list of uses, as soon as I chose one it rebooted, so step 14 was done in normal startup. Attached Hijackthis, AVG antispyware and Combofix logs Is anything in these causing the slow running? Any help would be much appreciated.
