Avast randomly popped up and told me: "Suspicious files have been detected (using a heuristic method). This may be a sign of malware infection."
Short of deleting this and probably having to reinstall my OS what should I do?
Also, when I scan this file, specifically, with avast, or the entire systems32 folder, no threat is ever found, it was only this once that Avast randomly told me it may have a malware infection? Is this something to be worried about.

Man you got a real long name. Please do not use your e-mail as nickname. BTW welcome to Avast! forums.
A screenshot of the alert would be helpful. Also the name of the file that Avast! detected.
Is the file popping up continuously or just that one time ? How is the comp. behaving ?
Have you done a full scan with avast! ? Did it find anything ?
Follow this guide: http://forum.avast.com/index.php?topic=53253.0
and attach ( Do not copy/paste ) logs for AdwCleaner, malwarebytes', OTL, and aswMBR.exe.
An expert in the removal of malware will help you.
Some time may pass before getting help due to time zone differences. Meanwhile do your scans and attach the logs.

Explorer.exe? hhhmmm...try to copy that file into another computer with the same Operating System and version. that was the trick I've used. worst scenario, you have to format your computer. you must put into habit of Creating a restore point with windows. so that you have a backup plan when your computer crashes. most of the user here don't know how to use that special function of Windows.

....worst scenario, you have to format your computer.
No need to format your OS AdoptablePeach, just attach the logs and let a specialist to look at them.

How's your computer running now?
-
Here is the log after the reboot. My computer is running fine now. Thank you for all of the help :D
-
np ;)
It is necessary to uninstall ComboFix :
- Click Start (or (http://amf.mycity.rs/pg/images/VistaStartButton.png)) then Run.
On Windows7 or Vista you may use Start Search field if Run is not available.
- In the line of text type in (Copy) the following:
ComboFix /Uninstall
Note that there is a space between " ComboFix " and " /Uninstall " .
- then click OK (or press Enter ).
Wait for the uninstall process is complete.
------------------------------------------
> Re-run OTL and click on CleanUp! button.
You will be asked to reboot the machine to finish the cleanup process, choose Yes.
After the reboot all the tools we used should be gone.
Note: Some more recently created tools may not yet be removed by OTL. Feel free to manually delete any tools it leaves behind.
-----------------------------------
I recommended to keep Malwarebytes and to use MCShield if you will.
You may download MCShield from one of the following links:
MyCity - Official download link (http://amf.mycity.rs/mcshield/)
Softpedija - Mirror download link (http://www.softpedia.com/get/Antivirus/MCShield.shtml)
It will prevent infection by computer via USB flash drive, mobile phone or any other memory card.
And not only will prevent infection, but it will immediately clean flash drive, memory card or external HDD.

Thanks again man. Also should I keep adwcleaner or not?

Thanks again man. Also should I keep adwcleaner or not?
You may use if you will, but before each use you need to download fresh&updated versions and after each use, uninstall AdwCleaner.
