May I ask why you are scanning for malware in Safe Mode?
A. If you feel that the problem is your logitech software for mice & keyboards, then try to replace them to resolve your problem.
B. In the meantime, you can uninstall the new AV you put on your machine:
- Uninstall Avira Antivir Completely:
http://www.themisteriosos.com/uninstall-avira-antivir-completely.htm- Avira RegistryCleaner:
http://www.avira.com/en/support-download-avira-registrycleaner - How to Remove Antivir Antivirus:
http://www.pchell.com/virus/uninstallantivir.shtmlReboot your machine after each uninstall process.
C. Clean up your machine with something like CCleaner, a free system optimization, privacy and cleaning tool. There is a
Slim version available as well at
http://www.piriform.com/ccleaner/builds – 4th option down. It removes unused files (cache, temporary Internet files, etc.) from your system, allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. Additionally it contains a fully featured registry cleaner.
D. Install Avast:
1. Save a copy of Avast and save it to your HDD:
http://www.avast.com/download-software – all products – 6.0.1125
2. Download the Avast Uninstall Utility
http://files.avast.com/files/eng/aswclear6.exe and save it to your HDD.
3. Disconnect from the Internet at this time.
4. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
5. If Step 4 fails, boot into
Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool.
If you did not previously uninstall ALL Avast versions and products in Safe Mode, do so now one at a time with a reboot in between each uninstall.6.
Reboot.
7. Install the newest version of Avast and adjust your exclusions if needed, and
reboot.
8. Get Internet access and register your copy or add the license key for Free, Pro, or AIS.
9. Update the Avast definitions.
E. Run an Avast Quick scan in
normal mode (the first time takes longer after a clean install), and post your results.
Let us know if this fixes your problems.
