Belongs to the Speedtouch software suite
part of speedtouch modem that i have
its about as useful as an AOL user sitting at a computer!
Some versions seem to disrupt USB devices, can conflict with flash memory card readers. Removing it from the startup will not effect the operation of the speedtouch modem.

Drst.exe has caused me endless problems with USB connectivity, plus it slowed my PC down massively and stopped it shutting down properly if at all. Now I have removed Dr Speedtouch, my PC is back to normal and I can synchronise my phone with Outlook with any problems. I recommend removal!!!

My recommendation would be to leave it alone but simply refuse it permission to communicate via your firewall. Its transmission of data masks my view of outgoing transmissions from other possible threats such as trojans. PC users need to be able to see those on the transmission meter in the toolbar tray.

It's diagnostic tool released by Thomson.
would it do any harm if I remove it from the registy(I'm running xp pro)
If you have changed from a Speedtouch modem to another, you will still have drst.exe hanging around on your system. But you no longer need it.

Best practices for resolving drst issues

A clean and tidy computer is the key requirement for avoiding problems with drst. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the drst.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
