Hi,

Here is a chronology of my problems:

1. Few weeks ago I was badly infected. AVG antispyware wouldn't start, and adaware, spybot and superantispyware were keeping finding the same stuff and cleaning it again and again without any success. I came here to the HJT forum for some cleaning. Everything seemed ok then.

2. Unfortunately, a few days after the cleaning I got 2 or 3 IE popups (I never use IE). Malwarebytes found and "clean" some malware. Everything seemed ok after that.

3. Few days ago my computer started acting weird. First example: I opened a folder and saw the files in it disappearing right in front of my eyes, but they were back there after closing and reopening the folder. Second example: I write a text and suddenly some letters disappeared then reappeared and I can't type the text where the cursor is situated. I launched all my antispyware/anitmalwares: nothing.

4. Today everytime I turn my computer on, Avast! is showing a popup with the following message: "Avast! Warning Suspicious file found! A suspicious file has been detected (using a heuristic method). This may be a sign of malware infection. File Name: C:\WINDOWS\SYSTEM32\process.exe Type: Rootkit hidden process"
I restarted my computer twice in a row and allowed Avast! to scan on reboot but the same popup still coming back.

Basically, I am quite sure that I am infected, but I can't find by what.

Here's what I used till now:
- CCleaner
- Ad-Aware
- Spybot SD
- Superantispyware
- Malwarebytes

And I launched two antispywares:
- Avast!
- Kaspersky online scanning (after shutting down Avast! of course)

All the logs were clean!

If my computer is clean I am wondering:
- I found nothing, so why is my computer acting weird from time to time for no reason?
- Why do I keep receiving this message from Avast!?

Can you help me, please?

Thanks!

Is there a log from Avast that you can copy/paste?

I don't have a log of the scan. I just scanned again and the result is "no files infected". Should I get a HJT log?

Hello Lov3,

I see that you have an HJT log posted here: http://www.bleepingcomputer.com/forums/t/186548/certainly-infected-but-by-what/

We do not allow more than one topic for the same computer and the same issue as this causes confusion, and in this case may make the disinfection process more difficult.

This leaves you with a choice:

1) Have this thread reopened and the HiJack This log topic deleted

OR

2) Keep this thread closed and wait for assistance in the HiJack This log forum. Please note that that forum is VERY busy.

Please send a Private Message indicating your choice.

Assuming you wish assistance in the HiJack This forum, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic. Good luck with your log.
