I feel my computer going slow down – particularly in the Windows Explorer. Since the AVG is very heavy – I want to remove it and replace with other antivirus. Frankly speaking, AVG have done their job well in protecting me from viruses. But it’s really burden my computer, it eats the memory and burden the processor itself. While scanning, practically I can’t work anything with my computer.
So, since I often use the online scanning of trendmicro – and I got a free subscription for 1 year, then this is my first choice to try.
I uninstall the AVG, then install trendmicro. It asked me to uninstall Adware2008. I did it. Then the installation seems okay. I didn’t enable the firewall since I am under ISA proxy. But the update process took soooooo loongggg – then stuck. I couldn’t terminate the process.
Then I tried to uninstall. Error message came out. I couldn’t be uninstalled. I used Cleanse Uninstaller, and do “Forced uninstall” – but the Cleanse Uninstaller could not finish its job. It’s hanged and “unresponse” error came out.
I had to do uninstalling manually. I cleaned up all the file remained in the C:/Program files & C:/Documents and Settings/All Users/Aplication Data/ ; also run CCleaner to clean the registry. The services still went on, I delete it by deleting the registry through command prompt (Start->Run) regedit. Delete all the entries from Trendmicro:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services
Feeling everything okay, I start installing Kaspersky Antivirus2009. But the Installation didn’t want to go on, it said that there is still TrendMicro. The uninstaller from Kaspersky couldn’t do uninstallation.
I went back to “Regedit” and delete all registry entry of TrendMicro from HKEY_LOCAL_MACHINE/SOFTWARE, back to Kaspersky installation; but it still refused – asking to uninstall TrendMicro.
Almost frustrated, I started google and found
Windows Installer CleanUp Utility
in Microsoft Help and Support site.
I downloaded it and installed it – then run. It showed up a list of the programs in my computer. I saw TrendMicro was there. I select it and do clean it. Marvelous! Now, the Kaspersky installation goes through.
