Is my PC actually infected?
Heres why:
I ended up quarantining ChromeInst with mbam since it wouldnt really make a difference because Chrome is already installed. Updated avast, mbam and superantispyware and decided to run a full scan again. It's the first time Superantispyware ever detected something here:

C:\SYSTEM VOLUME INFORMATION\_RESTORE{34DE795F-5055-4051-B2C2-DA24901A7B3E}\RP17\A0005890.EXEChecked it online and superantispyware database says this is like a leftover from a threat that was already removed, so i just deleted it.
Since this wasnt being detected yesterday, I presumed it could be related to the quarantined ChromeInst.exe and guess what? I tried to restore it just to see if superantispyware would detect anything but it just wouldnt work - it would disappear from MBAM's quarantined items list after clicking the "restore all" button but it wouldnt show up in the folder it was in before. Then I checked mbam's quarantine list and it was showing up once again - ended up just removing it and now it seems nothing is being detected.
Any ideas why this happened? Maybe today's Superantispyware definitions started detecting ChromeInst.exe and found it in mbam's quarantine or something?
And most important: should I get worried about this? Maybe run OTL and ask essexboy to check if the logs are ok? Thanks again.
