User Comments

habe gestern ein Update von Tuneup utilities runtergeladen, da ich per email eine Nachricht bekam, meine Version sei nicht mehr auf dem neuesten Stand. Nun heißt das Ganze AVG User Interface mit neuem Ikon. Als erstes waren meine ganzen Ikons weg, ebenso die Taskleiste - der Bildschirm war schwarz. Zum Glück hatte ich noch Firefox an und konnte im Netz ein bisschen forschen, was zu tun ist. Nach langem Probieren habe ich dann über Strg-Alt-Entf. den Task-Manager aufgerufen und konnte über Windows-explorer.exe meine Ikons wieder zurück holen. Als nächstes kam mehrfach eine Werbung von AVG, ich sollte irgendeine Pro-Version kaufen. Habe ich weggeklickt. Dann merkte ich, dass mein Computer nachts sehr beschäftigt war, obwohl ich selbst keine Programme laufen hatte. Nun habe ich über Kaspersky das Programm blokiert, da ich mich nicht traue, es zu deinstallieren. Andere haben mehrfach Abstürze gehabt.

Best practices for resolving AVG Web TuneUp issues

The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active AVG Web TuneUp process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the AVG Web TuneUp.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. 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.
