Latest cwshredder from Trend Micro reported mine as contaminated. On Fix it went to the recycle bin. Restored it, ran cwshredder and it was ok.

this when being on my system wouldnt let me open my computer was hanging up my system.
uwdf.exe and alg.exe seem to be the problem processes I always get not too long after reinstalling xp home. So either my web browsing attracts these two, or it's a program that I install every time that holds these .exe's in the bundle. I always install kmplayer - zoom player - windows media10 - winrar - utorrent - unlocker - firefox - irfanview . I always reinstall XP home and have for over 5 years and always end up with these two processes causing explorer windows to take FOREVER to load. ALWAYS DELETE these .exe's,... I have never had a problem from deleting them.

Best practices for resolving uWDF issues

A clean and tidy computer is the key requirement for avoiding problems with uWDF. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
