First, whether it was iYogi that told you about remnants or not, now it doesn’t matter much. By now, it is better to run them anyway (as you don’t have the means to re-check it by yourself).

About getting rid of malware, why you are asking now if you had to do that first? If you re-read the topic, this suggestion was mentioned more than once.

Moreover, your topic in the “Viruses and Worms” subforum received the correct answer. You have there the links and instructions what to download, how to proceed, and then to post back there (in that same topic you started) the resulting logs.

Please don’t get me wrong. You are welcome to ask. Just try to follow the suggestions.

Now keep reading the relevant info BEFORE running the removal utilities you need to run. (BTW, the removal utilities are for deleting potential remnants that can conflict with Avast and other security tools. The key word is “remnants”, so they are not so easy to spot by yourself. First see if the “old” program is listed in “Add / Remove Programs”. If they are, uninstall them, reboot and follow the instructions for the respective removal utility for that old tool).

If you have any doubts, just come back and ask.

Please report back, in any case.
