I defrag my drive almost daily and run the normal system tools to optimize my machine. I keep my Norton Antivirus 2006 virus definitions updated and run scans frequently. I also run Ad-aware and Spybot Search/Destroy weekly.
I followed the HijackThis instructions and ran Spybot, Ad-aware, MS Antispyware Beta 2, Ewido Antimalware 3.5, Panda Active Scan, Trend Micro's PC Cillan, Killbox, and ATF Cleaner. All programs found problems and fixed everything (but a few infected cookies).
In terms of computer specs, I'm running Windows XP with SP2 installed. HP Pavilion a350n with P4 processor 2.8 ghz, 1 gb RAM, 160 gb hdd with 27% free space. (I'm in the process of deleting files to improve storage capacity).
I followed the instructions from a similar thread posted below.
I deleted "prefetch" files, ran disc clean up, and ran defrag (again). I didn't understand "sfc /scannow" instructions. I can't seem to find my XP CD. In addition, I've been attempting to download the Tune-Up 2006 trial, but the Tune-Up website is not loading.
Click start then run, type prefetch then press enter, click edit then select all, right click any file then click delete, confirm delete
Click start, all programmes, accessories, system tools to run disc clean up, then from system tools, run disc defragmenter.
Click start then run, type sfc /scannow then press enter, you need the XP CD and Windows File Protection will show a blue onscreen progress bar, when the bar goes, reboot
Download and install Tune Up 2006 Trial
