Recently I have been getting reports of problems on my company's systems of becoming unstable & locking up. Then more of the same on my home systems, my friends & families system's of whom all use AVG as recommended by me. If you are experiencing any of the following.. PC Loads up & all appear's fine until you try to run programs in which case they the mouse courser shows something loading & then nothing.Unable to Install/Uninstall anything as initiating those process's just does exactly the same thing as mentioned above.increased hard drive activity for example, nothing happening but the hard drive activity light or sound indicates extensive activity.Boot failure into windows with persistent sticking at log in screen.Booting into safe mode everything loads perfectly fine, just not in normal mode.You need to Uninstall AVG & I suggest installing another Anti-Virus like Avast which is free to use & works great! Windows 7 wont let you uninstall anything in safe mode, so you need to do the following. Once booted into safe mode, click start & in the search box type CMD & hit enter. A Black box will load up. Now select, copy & past the following into the box. Code:"HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer" /VE /T REG_SZ /F /D "Service"Dont use CTRL + V, right click on your mouse & click past, then hit enter. Now copy & past the following & hit enter Code:net start msiserver"Now, go to control panel, uninstall AVG, reboot your computer & you will notice everything is working great, may be a little slow at first, thats due to the lock-ups & problems caused by AVG. Then fine a new Anti-Virus & your sorted. This problem was discovered by myself & AVG appear's to uncontrollably quarantining your entire HD & any attempt to use your OS/Files is prevented once AVG has loaded up & its services, which is why it loads up fine, but then nothing happens then on. We contacted AVG regarding this problem & they are investigating but they have let me know this is a solely a windows 7 problem & no reports have been found on any other OS. Enjoy!
