    Hello,

    I did a scan with Zemana Anti-Malware because my pc will randomly exit full-screen screen applications back to the desktop for no apparent reason. This scan picked up a suspicious root ca, BUT, because I had not used Zemana before, I accidentally deleted it immediately before looking at any details. I ran Malwarebytes and Zemana again and apparently the PC is clean but today I have someone from Bulgaria logging into my Steam Account from an unknown computer.

    I am very concerned and to add this the previous owner of this PC must have been using a cracked version of Avira because I could not log into the suite properly or find out any account details, it was a premium version but appeared as a trial period...so I removed it immediately but I suspect this might have been the root certificate issues origin.

    Do I need to change passwords of everything? Should I do this on this PC? Or should I clean this PC first then do this?

    Could someone offer some help I am not too great with things like this?
    Thanks
    GS

    Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer.

    1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
    2. The fixes are specific to your problem and should only be used for this issue on this machine.
    3. If you don't know or understand something, please don't hesitate to ask.
    4. Please DO NOT run any other tools or scans while I am helping you.
    5. It is important that you reply to this thread. Do not start a new topic.
    6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
    7. Absence of symptoms does not mean that everything is clear.

    If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line.
