Undetected Virus Infecting All My Files?

It was a normal day when I scanned the computer and I found a virus.So I moved it to chest.
I wanted to make sure if there was more virus so I made a thorough scan.Yes,I was right!More virus!
I thought maybe something was infecting the files so I scanned again,and yes,more virus.
I think there’s an undetected virus that’s infecting all my files.
I have to scan my computer every time I finish a scan to protect myself from viruses.It’s making my computer lag when I’m browsing through the web or playing a game,probably at most of the time I’m using the computer.
Just now a popup appeared too.
Someone please help me to try and find the undetected virus using some way please!
I’m going mad with all these scanning :cry:
I tried deleting all the viruses in chest but to no avail.oh no.A window just popped up and said a file from System Volume Information/restore_ etc. (can’t remember them all,i’ll check them in the chest after scan is finished) was infected.Does this have any effect on my system?

No need to delete virus in the chest, they can do you no harm
Does the virus have a name?
Is the popup warning from Avast?

I canceled the scan because I was going to sleep and my computer’s overheating…I think.:frowning: my adobe dreamweaver got affected…
I’ll list the System Volume Information ones since they look very important.The ones I did before this scan I had already deleted them all.
A0033388.exe - from C:\System Volume Information_restore{4673EB34-264D-4CB2-B13E-A9C63AAA15A2}\RP49\A0033388.exe
A0033389.exe - from C:\System Volume Information_restore{4673EB34-264D-4CB2-B13E-A9C63AAA15A2}\RP49\A0033389.exe
A0033450.exe - from C:\System Volume Information_restore{4673EB34-264D-4CB2-B13E-A9C63AAA15A2}\RP51\A0033450.exe
A0039845.exe - from C:\System Volume Information_restore{4673EB34-264D-4CB2-B13E-A9C63AAA15A2}\RP51\A0039845.exe
A0044082.exe - from C:\System Volume Information_restore{4673EB34-264D-4CB2-B13E-A9C63AAA15A2}\RP61\A0044082.exe

EDIT: Oh yeah,the virus somehow deleted my RocketDock too.I’ll check for anything that got deleted with it.
EDIT2: The virus also somehow spoiled my Google Chrome.After that I uninstalled it and tried to install it again.But the installer just wouldn’t open,however there were processes.Google Chrome was my fav browser :frowning: please fix this problem
EDIT3: Back again,it spoiled one of my MSN Messenger’s data and now I can’t access it.

Thanks for the solution it solved ALMOST everything.However as many times as I did a scan and removed them there will always be this virus.
rundll32.exe - (Heuristics.Reserved.Word.Exploit)
I don’t think it looks like a virus.Every time I remove it it appears again.Maybe it’s a computer thing?

Where is the file rundll32.exe found whenever detected?
