UPDATE-SOLVED: Ok so after messing around with things, it appears it is NOT the Avant Browser's problem but AVAST antivirus's latest update that screws things when you launch your Avant Browser. (I am still diagnosing WHY this is happening but you only want your computer to work right so read on for the instructions if you want to do it yourself or CONTACT ME if you want me to do it for you [existing clients that I have the ability to connect to directly].
To solve this yourself: first RIGHT CLICK on the Avast Icon on the systemtray and choose ABOUT AVAST and then click on the License Key and (copy/paste this
C90591623H1200A1113-RKNATNJP )
Then, CLICK HERE to download the latest set of virus definitions. (Choose RUN or SAVE and then Run when download complete).
RESTART your computer after this is done. That should do it. Now, if you had the virus already remove the avant browser, you can reinstall it by DOWNLOADING IT HERE.
UPDATE: This is very new so please understand I am working on it now. It appears the problem is within either the Avant browser and/or the antivirus with which it recognizes the "IAS" or internal account of the avant browser. As you may or may not know, when you open your avant browser, it will automatically connect to your own account where your bookmarks and autofill are saved and if there is an error connecting to that server, in this case, it is trigering the antivirus as a trojan detected. Therefore the best solution at this time is to cancel whatever the antivirus tells you to do, restart your computer and DO NOT use the avant browser. Use the alternative web browser such as Google Chrome and/or Mozilla's Firefox. I do not nor ever, suggest using the Internet explorer in this case especially since the Avant Browser emulates the Internet explorer exactly, the problem may also show up if you try to use that browser.
